产品详情


332.jpg


Model HVH piston type solenoid valve is a twice open-type solenoid valve to be suitable to one-way flow.

·Model HVH piston type solenoid valve is used on the liquid, air suction and hot vapor pipes of the refrigeration, cold storage and air conditioning facilities.

·The coil of varies voltages is available for Model HVH piston type solenoid valve with a universal valve body.

·Model HVH piston type solenoid valve could be supplied in whole or in split, that means valve body and coil could be supplied separately.
