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

The simple system configuration permits sharp response. The large capacity system configuration without connection loss allows the use of smaller valves and piping.

27 Series Construction/Working Principle/Component Parts () () R () Closed center () () R This is a port switch valve in which the shaft 7 - extending from the driving piston ee opens/closes a pair of poppet valves 6. The poppet valve has a pressure balancing mechanism in which port () 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 (P) and (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 (P) 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 (P) and port () (DRW ()). The upper poppet valve continues to close the port (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 (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 () and port (R) (DRW ()).

30 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. large capacity and economical system. This valve provides twice the system capacity of the conventional circuit. Therefore, it is possible to downsize or sizes (for example, a conventional circuit can be changed to a 5 or a 0). 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 0% 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.
