4 Way Reversing Valve U Bend

THE 4-WAY REVERSING VALVE IS THE KEY COMPONENT TO PROVIDE HEATING AND COOLING FROM THE SYSTEM TO THE AIR CONDITIONED SPACE BY REVERSING THE FLOW DIRECTION OF REFRIGERANT.
IT IS USED AT ROOM AIR CONDITIONERS, PACKAGED AND CENTRAL AIR CONDTIONERS.
THE REVERSING VALVES ARE DESIGNED FOR HEAT PUMP SYSTEMS WITH CAPACITY FROM 3KW TO 580KW. THEY ARE SUITABLE FOR MOST REFRIGERANTS AS R22-R410A-R314A.

HOW TO WORK OF 4-WAY REVERSING VALVE
THE 4-WAY VALVES ARE USED IN REVERSIBLE APPLICATIONS SUCH AS HEAT PUMPS OR REVERSIBLE AIR CONDITIONING UNITS AND CHILLERS. THE 4-WAY VALVE ALLOWS AN INVERSION OF THE REFRIGERATION CYCLE ,CHANGING FROM COOLING MODE IN SUMMER TO HEATING MODE IN WINTER. THE CYCLE INVERSION IS INITIATED BY A SMALL SOLENOID PILOT VALVE, WHICH TRIGGERS THE MOVEMENT OF A SLIDE,THUS INVERTING THE FLOW DIRECTION OF THE REFRIGERANT. THE VALVE IS CONNECTED TO THE SUCTION AND DISCHARGE PIPES.
IN THE CHANGEOVER TIME, WITH A MINIMUM PRESSURE DIFFERENTIAL HAPPENS. ALSO GUARANTEES A MINIMUM PRESSURE DROP AND VERY LOW RISK OF LEAKAGE.
