3 Series 1 Application Example 1. Relief regulator (Rapid tank internal pressure setting) (Relieving type regulator e.g. AR000) 5. steps directional control setting Relieving type diaphragm regulator Large exhaust capacity. Silencer is easy to connect.. Air blow (As port directional control regulator valve) (AR000, etc.) 3 VALVES IN ONE A simple main system is ensured. Remotely controlled by compact pilot system. 6. Multiple steps pressure control (Toward stepless control) Air motor, etc. External pilot port solenoid valve (For on/off operation) Diaphragm regulator (For pressure setting) Solenoid on/off operation controls the air flow. Setting can be changed by remote control. (Remote control) 3. Constant pressure supply and driving (As 3 port directional control regulator valve) Note) The pressure is about 0.01 MPa when OFF because of leakage. The main driving system is simple consisting of one 1 only. Remotely controlled by compact pilot system. Throttle Electropneumatic regulator (Solenoid valve) (Regulator) Actuator s appropriate pressure control saves energy (Air). Steplessly and remotely controlled by electric signals. Flexibile pressure control for welders. 4. Balance and driving (External pilot (Relieving type solenoid valve) regulator) Actuator driving system becomes simple. The large capacity relief valve rapidly responds and sets the balance pressure. Solenoid on/off operation drives the cylinder. Common exhaust. Caution Caution When the outlet side capacity is small, install a speed controller AS000, in the pilot pipe to lower the pilot pressure for vibration prevention. (Meter-in) ((5) steps directional control setting, (6) multiple steps pressure control setting) Relieving type regulator such as AR000, etc. should be used as pilot regulator in the application.(when the non-relieving type is used, pressure cannot be changed from high to low.) A sensitive regulator such as the ARP3000, etc. should be used as a pilot regulator on the low pressure side, particularly with 5. steps directional control setting and 6. multipje steps pressure control. (Using a non-sensitive regulator may cause unstable pressure.) 1948

6 Power Valve: Regulator Valve Series 1 Construction/Working Principle/Component Parts (1) When Port (A) pressure is high Relief exhausting () Setting pressure condition (3) When Port (A) pressure is low Pressure reducing supply The balance between the acting force F1 of the pilot pressure (port P1) over the upper surface of the pressure regulating piston 3 and the acting force F of the pressure at port (A) leading to a space under the piston through the feed back flow root closes a couple of poppet valves 6 and sets port (A) pressure that corresponds to port P1 pressure. The poppet valves are backed up by spring 4 - in the pressure balance structure by means of port (A) pressure. (DRW ()) When port (A) pressure exceeds port P1 pressure, F becomes larger than F1, and the pressure regulating piston moves upward, opening the upper poppet valves. Thus air is released from port (A) to port 3 (R) (DRW (1)). When port (A) pressure lowers enough to restore the balance with port P1 pressurs, the regulator valve returns again to the DRW () condition. When port (A) pressure is lower than port P1 pressure, F1 becomes larger than F, and the pressure regulating piston moves downwards, opening the lower poppet valves. Thus air is supplied from port P1 to port (A) (DRW (3)). When port (A) pressure rises enough to restore the balance with port P1 pressure, the regulator valve returns again to the DRW () condition.

12 Power Valve: 3 Position Valve Series 3 Realize a variety of circuits using simple components. Conventional system configuration Intermediate and emergency stops of large-sized cylinders Intermediate and emergency cylinder stops The 3 position closed center valve produces a simple and large capacity system. There were not many suitable large capacity 5 support valves available with a 3 position closed center. There were not many suitable -port valves for stopping. System configuration when using A large capacity system without connection loss. = (Valves and piping can be made smaller.) ) ( ) ( ) ( Terminal deceleration and an intermediate speed change circuit can be produced easily. The simple system configuration permits sharp response. The large capacity system configuration without connection loss allows the use of smaller valves and piping. For example, when solenoid (b) of valve (A) is turned off while the cylinder is extending, the exhaust port closes and cylinder movement decelerates. = (Emergency stop valve) )( )( )( )( Vacuum suction and release The 3 port, 3 position double solenoid that permits vacuum suction, release, and suspension (closed) is ideal for a system where many valves are used. Suction filter Vacuum pad Vacuum pump Pressurized air (A) (Speed change valve) (Switching valve) Universal porting could be used as a selector/ divider valve The pressure balancing poppet valve that permits any flow direction allows sequential switching operation, preventing blow by and air entrainment. Two-stage directional control selection Direction divider Stroke Stroke Time Time There is no blow-by when switched from vacuum suction to vacuum release or vice versa. Caution When maintaining the vacuum of port (A), the vacuum may decrease due to leakage from the vacuum pad or piping. Conduct vacuum suction at the vacuum adsorption position. Furthermore, it cannot be used as an emergency cutoff valve. For operation control of double acting cylinders Two power valves driven by a double acting cylinder allows operation control in 9 positions (3 positions x 3 positions = 9 positions) including slow stopping, acceleration, and deceleration. 3 x 3 = 9 positions Reciprocation Pressure center Closed center Exhaust center Pressure & closed center Exhaust & closed center Slow stopping or decelaration Caution This valve is not a non-leak specification, and thus cannot be used for long term intermediate stops or emergency stops. 1957

27 Series 3 Construction/Working Principle/Component Parts (1) (A) R 3(R) () Closed center (3) (A) R 3(R) This is a 3 port switch valve in which the shaft 7 - extending from the driving piston ee 3 opens/closes a pair of poppet valves 6. The poppet valve has a pressure balancing mechanism in which port (A) pressure is constantly applied from the back and the center spring 4 is acting as a backup. When neither the pilot solenoid valve a nor b are energized (or when air is exhausted both from the port 1 (P1) and 3 (P) of the air operated type), no force will act on the working piston, and the spring closes the poppet valve, thus the valve assumes the closed center position (DRW ()). When the pilot solenoid valve a is energized (or when pressurized air enters through the port 1 (P1) of the air operated type), pilot air that enters the space above the working piston pushes down the piston and opens the lower poppet valve, thus connecting the port 1 (P) and port (A) (DRW (3)). The upper poppet valve continues to close the port 3 (R) by means of pressure balance and the spring. When the pilot solenoid valve b is energized (or when pressurized air enters through the port 3 (P) of the air operated type), the pilot air that enters the space under the working piston pushes the piston upward and opens the upper poppet valve, thus connecting the port (A) and port 3 (R) (DRW (1)). The lower poppet valve continues to close the port 1 (P) by means of pressure balance and the spring. 310 (Air operated) Port 3 (P) Port 1 (P1) Port 3 (R) Port (A) Port 1 (P) 30 (Air operated) Port 1 (P1) Port 1 (P) Port (A) Port 3 (R) Port 3 (P) Component Parts No. Description Material 1 3 Body Cover Working piston Aluminum alloy Aluminum alloy Aluminum alloy 4 Center spring Stainless steel 5 Valve guide Aluminum alloy 6 Poppet valve Aluminum alloy, Rubber 7 Shaft Stainless steel 8 Manual override POM 9 Sub-plate Aluminum alloy 197

30 Power Valve: Economy Valve Series 5 Three functions (pressure regulator, switching valve, and speed controller) are provided by a single valve. The conventional valve combination circuit has been condensed into a single valve. A large capacity and economical system. This valve provides twice the system capacity of the conventional circuit. Therefore, it is possible to downsize 1 or sizes (for example, a conventional 3A circuit can be changed to a 5A or a 0A). It is economical, as its performance cost (system price/effective area) is one half of the conventional type. (Comparison based on SMC data.)

32 Power Valve: Economy Valve Series 5 Energy-saving Lifter Simple Two economy valves and a tank move the double-acting cylinder to raise and lower heavy objects. Energy-saving The balancing air reciprocates between the lower cylinder chamber and the tank, thus not being consumed. Low pressure air alone is exhausted from the upper chamber in every cycle, so the air consumption is reduced to 0 to 30% of the air consumption by the double acting cylinder with an ordinary change over valve. Excellent operation control The economy valve sets pressure and permits high speed and low speed operation as well as suspension of operation. While the piston moves up and down, the valve controls speed change in the middle of strokes, terminal deceleration, inching, and emergency stops. Simple operation The pilot system is composed of a small regulator and solenoid valve (which is unnecessary for solenoid style), remote controls the economy valve. Therefore, change in the pilot system sequence allows selection of a cylinder operation mode. Change in the large capacity main piping system is not necessary. <System configuration and operation of circuit in which external pilot solenoid is used> Action TANK For upper chamber setting Upper cylinder chamber Lower cylinder chamber For lower chamber setting The two economy valves (hereinafter called ) X and Y and a tank composes a main system that drives the double acting cylinder, and the small regulator (hereinafter called REG) and pilot valve (hereinafter called SOL) remote control the economy valve.

39 Series 5 Basic Type/Construction/Working Principle/Component Parts 1. 3 (R) (A) Reduced pressure supply Note) With this valve, the port 3 (R) is a supply port and port 1 (P) is an exhaust port.. Closed center 3. (A) 1 (P) Throttled exhaust When the pilot solenoid valve a is energized (or when pilot pressure is applied to the port P1 of the air operated type) while the port P1 is under the pilot pressure, reduced pressure is supplied from the port 3 (R) to the port (A). The acting force of the pilot pressure (port P1) reaches the space under the pressure control piston 3 pushes the piston upward and opens the poppet valve 6. Thus air is supplied from the port 3 (R) to the port (A). The air entering through the port (A) flows through the feedback passage to the space above the piston, and when its pressure balances with the pilot pressure under the pressure control piston, the poppet valve closes, thus setting the port (A) pressure corresponding to the pilot pressure (port P1). (port P1 pressure: port (A) pressure = 1:1) When the reduced pressure is supplied from 3 (R) to (A), air will not be exhausted from (A) to 1 (P) even when the pilot pressure (port P1) is larger than the port (A) pressure. When neither the pilot solenoid valves a or b is energized (or when no pilot pressure is applied to the ports P1 and P of the air operated type), no acting force is applied to the pressure control piston 3 and operation piston 9, and the spring 4 closes both poppet valves 6, thus the valves assume the closed center position. While the port (A) is being pressurized, air will not be released even if electrical power to the pilot solenoid valve a is turned off (or pilot pressure is released from the port P1 of the air operated type). When the pilot solenoid valve b is energized while pilot pressure is in the port P (or when the pilot pressure is applied to the port P of the air operated type), an acting force generated above the operation piston 9 pushes the operation piston down, and thus the port 1 (P) and port (A) are connected. At that time, the lower poppet valve 6 opens by the degree preset by the needle 11. (Counterclockwise rotation of the needle opens the poppet valve.) The upper and lower poppet valves operate independently. When the pilot solenoid valves a and b are energized alternately (or when pilot pressure is applied to the ports P1 and P of the air operated style alternately), the supplied reduced pressure (3 (R) (A)) can be throttled and exhausted ( (A) 1 (P)).

(A) 1 (P) Fully open exhaust Note) With this valve, the port 3 (R) is a supply port and port 1 (P) is an exhaust port. 4. (A) 1 (P) Throttled exhaust When the pilot solenoid valve a is energized (or when pilot pressure is applied to the port P1 of the air operated type) while the port P1 is under the pilot pressure, reduced pressure is supplied from the port 3 (R) to the port (A). The acting force of the pilot pressure (port P1) reaches the space under the pressure control piston 3 pushes the piston upward and opens the poppet valve 6. Thus air is supplied from the port 3 (R) to the port (A). The air entering through the port (A) flows through the feedback passage to the space above the piston and when its pressure balances with the pilot pressure under the pressure control piston, the poppet valve closes, thus setting the port (A) pressure corresponding to the pilot pressure (port P1). (port P1 pressure: port (A) pressure = 1:1) When the reduced pressure is supplied from 3 (R) to (A), air will not be exhausted from (A) to 1 (P) even when the pilot pressure (port P1) is larger than the port (A) pressure. Construction When neither the pilot solenoid valve a nor b is energized (or when no pilot pressure is applied to the ports P1 and P of the air operated type), no acting force is applied to the pressure control piston and operation piston, and the spring 4 closes both poppet valves 6, thus the valve assumes the closed center position. While the port (A) is being pressurized, air will not be released even if electrical power to the pilot solenoid valve a is turned off (or pilot pressure is released from the port P1 of the air operated type). Pilot valve When the pilot solenoid valve b is energized while pilot pressure is in the port P (or when the pilot pressure is applied to the port P of the air operated type), an acting force generated above 3 9 the operation piston 9, and pushes down the operation piston, and thus the ports 1 (P) and (A) are connected. At that time, the lower poppet valve 6 fully opens. When the pilot solenoid valves b and c are energized simultaneously while pilot pressure is in the port P (or when the pilot pressure is applied simultaneously to the ports P and P3 of the air operated type), an acting force generated above the operation piston 9 pushes the piston down and another acting force generated under the stopper 11 pushes up the stopper, and thus the ports 1 (P) and (A) are connected. At that time, the lower poppet valve 6 opens by the degree preset by the needle 1. (Counterclockwise rotation of the needle opens the poppet valve.) The upper and lower poppet valves operate independently. When the pilot solenoid valves a and b are energized alternately (or when pilot pressure is applied alternately to the ports P1 and P of the air operated type), the supplied reduced pressure (3 (R) (A)) can be throttled and exhausted ( (A) 1 (P)). The pilot solenoid valve c remains energized (or pilot pressure remains applied to the port P3 of the air operated type). By turning on/off the pilot solenoid valve c (or by supplying/exhausting pilot pressure to/from the port P3 of the air operated type) while electric power is being supplied to the pilot solenoid valve b (or pilot pressure is being applied to the port P of the air operated type), either throttling or fully open exhaust can be selected (decelaration/ accelaration) for the port (A) 1 (P).
