Shanghai Fengshen Refrigeration Controls Co. Ltd

Model Number: PWV1-1/2G Brand Name: FENSHEN Key Specifications/Special Features: Fenshen pressure controlled water valveis usually installed on the inlet of condenser, which can regulate the flow of cooling water according to the change of condensing pressureWhen condensing pressure of compressor rises, valve is turned up automatically, so more cooling water enters the condenser to accelerate the condensing of refrigerantReversely, when condensing pressure of compressor drops, valve is turned down automatically, so cooling water reduces and the condensing pressure is kept within certain rangeAdjust screw rod at clockwise rotation, the control pressure of valve increases, inversely, the control pressure decreases
