 Item: Refrigerator water pressure regulator adjustable   Introduction   PWV series pressure controlled water valves are 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.  The PWV condensing pressure regulating valve regulating method: Rotatable adjustment 'adjustment screw' clockwise turn the valve off a small counter-clockwise rotation, the valve opening large.   Type & data
