Automatically shut off Teflon Bellows Solenoid Valves
The Teflon Bellows Solenoid Valve automatically shuts off flow of highly corrosive or ultra pure liquids including acids, caustics, solvents and chlorine solutions. They can handle pressure, drain, or vacuum applications and do not require pressure to aid in opening the valve. The valves are spring return normally closed and direct acting with a simple push-pull plunger design. There is no minimum pressure required for operation.
A Teflon bellows shaft seal eliminates the need for an elastomer seal which can weaken as a result of chemical attack. The Teflon Bellows assures non-sticking operation and exceptionally long cycle life; over 2 million cycles. The bellows design also allows a stock valve to be used for vacuum or pressure. The poppet pressure seat insures bubble tight shutoff.
Materials of construction: Available in Geon® PVC, G-Polypropylene, and Kynar® PVDF.
Elastomer seals in FKM or EPDM.
