Precautions
Design Notes And Selection
Examples of inapplicable circuits
Inapplicable circuit example (Perfect valves: VF66□□, VS7-6-FPG, VS7-8-FPG)
*Residual pressure behind the exhaust needle may cause check valve malfunction in the perfect valve.
Inapplicable circuit example 2 (circuit with pilot check valve between actuator and solenoid valve)
*Residual pressure behind the exhaust needle may cause pilot check valve malfunction.
Installation
Example of interference with fittings
*If mounting to connection ports of solenoid valves, interference may occur with the fittings. Consult the catalog before installing.
