HVH Piston Series Solenoid Valve Of Refrigeration / Air Conditioning System,For Refrigeration Unit
Description:
* HVH piston type solenoid valve is a twice open-type solenoid valve to be suitable to one-way flow.
* 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.
* HVH piston type solenoid valve could be supplied in whole or in split means the valve body and coil could be supplied separately.
