(Return spring normally closed) When the pilot solenoid valve o is not energized (or when air is exhausted from the port (P) for air operated style), the valve body r connected to the piston y is closed by the return spring u. When valve body 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 body 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.

9 Specific Product Precautions e sure to read this before handling. Refer to front matters and 3 for Safety Instructions, and pages 7 to 9 for Port Solenoid Valves for luid Control Precautions. xternal Pilot Caution Pilot port (P) and 0(P) piping P and P piping should be as follows according to the model. Port (P) ir operated 0 0 xternal pilot leed port Solenoid xternal pilot 0 leed port xternal pilot Pilot exhaust (P) Installing a silencer to the exhaust port and the bleed port is recommended for noise reduction and for dust entry prevention. Piping Caution When high temperature fluids are used, use fittings and tube with heat resistant features. (Self-align fittings, eflon tubing, Copper piping, etc.) Pilot Solenoid Valve Warning 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. Caution 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.
