Available in both normally open and normally closed configuration, the 2/2 valve is supplied as a cartridge design and therefore can be arranged to offer multiple functions from a single block; reducing cost on expensive fittings and pipe work.

Please contact TWHC for manifold options or cavity details.

221AOSW 160 Bar Max. Inlet Pressure, 2/2 Normally Open Valve, DN3, 24V DC, Spring Return  POA

The Design

The wet pin design solenoid actuator has no dynamic sealing and therefore produces adequate force to directly actuate the valve with an orifice size of 2.5mm up to a maximum working pressure of 160 bar. For lower actuation pressures, the diameter of the flow gallery can be increased to deliver a much greater cross section of flow path for higher flow conditions.

For higher flow capacity, please see data sheet for the 2/2 pilot valves.
