When the 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 solenoid valve is energized (or when pressurized air enters through the port (P) of the air operated style), the air that has entered under the piston moves upward to open the valve element. When valve element closes When the power to the solenoid valve is turned off (or when fluid is exhausted from the port (P) of the air operated style), the 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 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 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.) he 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)). 5-3A VN5-A3AA VN5-A3AB VN5-A3AC VN5-A4AA VN5-A4AB VN5-A4AC 6-40A VN6-A3AA VN6-A3AB VN6-A3AC VN6-A4AA VN6-A4AB VN6-A4AC 7-50A VN7-A3AA VN7-A3AB VN7-A3AC VN7-A4AA VN7-A4AB VN7-A4AC VO30-00 (Refer to page 363 for details.) 360 Courtesy of Steven Engineering, Inc.-30 Ryan Way, South San Francisco, CA 94080-6370-Main Office: (650) 588-900-Outside Local Area: (800) 58-900-www.stevenengineering.com

Series Specific Product Precautions Be sure to read before handling. Refer to front matters 4 and 43 for Safety Instructions, and pages 7 to 9 for Port Solenoid s for Fluid Control Precautions. Pilot. Pilot port piping (P) and 0(P) piping should be as follows according to the model Port (P) 0 (P) 0 Bleed port 0 03 Bleed port Pilot exhaust 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, eflon tubing, Copper tubing, etc.) Mounting Direction of Pilot Solenoid Warning With external solenoids, the solenoid valves are not splash proof specifications, and so care must be taken not to get fluid on oneself such as when performing maintenance. Direction of mounting When replacing a valve, if an external solenoid valve is mounted in the wrong direction, it may malfunction or leak air. Use with Air-hydro Unit. Piping Surge pressure is generated between the cylinder and the during intermediate stoppage. o 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.. Air bleeding Series valves have no air bleeding port. Bleed air comes from the middle piping. Bleeding by a vacuum pump is more effective.. Hydraulic fluid urbine oil, rade ISO V3, with petroleum hydraulic fluid is recommended. 3.
