    • Product Description

    • Product Model

    • Technical Parameters

    • Product Description:

      · 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 not 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 means the valve body and coil could be supplied separately.
