PWV1G Fenshen Pressure controlled water valve
Detailed Product Description
PWV1 Fenshen Pressure controlled water valve is usually installed on the inlet of condenser, which can regulate the flow of cooling water according to the change of condensing pressure.
When condensing pressure of compressor rises, valve is turned up automatically, so more cooling water enters the condenser to accelerate the condensing of refrigerant. Reversely, when condensing pressure of compressor drops, valve is turned down automatically, so cooling water reduces and the condensing pressure is kept within certain range.
Adjust screw rod at clockwise rotation, the control pressure of valve increases; inversely, the control pressure decreases.
