ASCO 290 Solenoid Valves – Direct Acting Valve 2 Way NC NO

ASCO 290 Solenoid Valves Direct Acting

ASCO 290 Solenoid Valves Direct Acting

ASCO 290 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 290 solenoid valves consist of 2 way direct acting valves available in normally closed or normally open configurations.

Manufactured for demanding applications, the ASCO 290 solenoid valve can be supplied in straight-through body design made from bronze or stainless steel.

There are many optional features including visual an electrical position indicators or a stroke limiter.

NC = Normally Closed Valve

NO = Normally Open Valve
