V66800 2-way Normally Open/Normally Closed Shut-Off Solenoid Valve


The series 66800 are compact, lightweight, direct-acting solenoid Shut-Off valves which utilize a diaphragm design. These valves provide high flow capability by employing a balancing diaphragm that assures friction-free, low hysteresis motion. Normally closed valves are standard in this series, however, normally open configurations can be made for special applications. A fluorosilicon elatomer is used for the specially designed seat seal. Tight sealing is achieved by means of this seat design.
