Structure/Operation
With solenoid valve
Valve side exhaust
*Refer to the manufacturer's catalog for maintenance parts.
By applying pressure from the pilot port, the valve linked to the piston overcomes the spring force and actuating force and opens.
XLAV normally applies pilot pressure to the 1 (P) port. The valve opens when the solenoid valve is on and closes when it is off.
