They are suited to operate large bore cylinders as well as to simultaneously operate multiple cylinders and suspend their operation. Thus they can be used in the same way as the conventional air-hydro units. ir-hydro circuit: pplication example Basic circuit Conditions Supply pressure Hydraulic fluid Load Piping length Piping diameter 0.49 MPa ISO VG3 No load m, 3/8B (9 mm) CCVSO, /B (3 mm) CCVLO 3 3/4B (9 mm) 4 B (5 mm) Refer to ir-hydro Unit pages in Best Pneumatics No. (Series CC) for further information on air-hydro. When speed controller is mounted Connect a speed controller (Series S etc.) to port of (in order to protect the speed control valve from surges when cylinder operation is suspended, thus improving stopping accuracy). Skip valve function Combination of or more valves of provides a skip valve function. Connect the skip valve to the port side of a stop valve. 468

Working Principle 0, (N.C.) When the pilot solenoid valve i is not energized (or when air is exhausted from the port (P) of the air operated style), the valve element r linked to the piston t is closed by the return spring u. When valve element opens When the pilot solenoid valve is energized (or when pressurized air enters through the port (P) of the air operated style), the pilot air that has entered under the piston moves upward to open the valve element. When valve element closes When the power to the pilot solenoid valve is turned off (or when fluid is exhausted from the port (P) of the air operated style), the pilot air under the piston is exhausted, and the return spring closes the valve element. 0, (N.C.) In contrast with the N.C., when the power to the pilot solenoid valve is turned off (or when air is exhausted from the port 0(P) of the air operated style), the valve is held open by the return spring. When the pilot solenoid valve is energized (or when pressurized air enters through the port 0(P) of the air operated style), the valve element closes. 03 (C.O.) The valve element of the C.O. type, which has no return spring, is in an arbitrary position when air is exhausted through the ports (P) and 0(P). When pressurized air enters the port (P) (exhaust from the port 0(P)), the valve element opens, and it closes when pressurized air enters the port 0(P) (exhaust from the port (P)). Part no.

8 Specific Product Precautions Be sure to read before handling. Refer to front matter 4 for Safety Instructions, and pages 7 to 9 for Port Solenoid Valves for Fluid Control Precautions. esign Extended periods of continuous energization If a valve is continuously energized for long periods, heat generation of the coil may result in reduced performance and shorter service life. This may also have an adverse effect on the peripheral equipment in proximity. Should a valve be continuously energized for long periods, or its daily energized state exceeds its non energized state, please use an energy saving type C, energizing for long periods of time continuously, select the air-operated valve and use the continuous duty type of the VT307 for a pilot valve. Mounting. o not apply external force to the coil section. When tightening is performed, apply a wrench or other tool to the outside of the piping connection parts.. o not warm the coil assembly with a heat insulator, etc. Use tape, heaters, etc., for freeze prevention on the piping and body only. They can cause the coil to burn out. 3. void sources of vibration, or adjust the arm from the body to the minimum length so that resonance will not occur. Piping. pplied voltage When electric power is connected to a solenoid valve, be careful to apply the proper voltage. Improper voltage may cause malfunction or coil damage.. Confirm the connections. fter completing the wiring, confirm that the connections are correct. External Pilot Pilot port piping (P) and 0(P) piping should be as follows according to the model. Port (P) External pilot Bleed port External pilot ( ) External pilot 0 (P) Bleed port External pilot External pilot ( ) Pilot exhaust ( ) If the pilot air is not supplied, the valve position will not be held. Pressurize Port (P) or Port 0 (P) when using the product. Installing a silencer to the exhaust port and the bleed port is recommended for noise reduction and for dust entry prevention. Piping When high temperature fluids are used, use fittings and tubing with heat resistant features. (Self-align fittings, PTFE tubing, Copper tubing, etc.) Mounting irection of Pilot Solenoid Valve With external pilot solenoids, the pilot solenoid valves are not splash proof specifications, and so care must be taken not to get fluid on oneself such as when performing maintenance. irection of mounting When replacing a valve, if an external pilot solenoid valve is mounted in the wrong direction, it may malfunction or leak air. Use with ir-hydro Unit. Piping Surge pressure is generated between the cylinder and the during intermediate stoppage. To directly thread in the cylinder, use durable fittings (Stainless steel square nipples etc,) instead of ductile iron fittings (JIS B 30) or steel pipe fittings (JIS B 30). When is installed away from the cylinder, use a high-pressure rubber hose (JIS B 6349) instead of steel pipe, when possible.. ir bleeding valves have no air bleeding port. Bleed air comes from VNB the middle piping. Bleeding by a vacuum pump is more effective. 3. Hydraulic fluid SGC Turbine oil, Grade ISO VG3, with petroleum hydraulic fluid SGH is recommended. 4.
