Liquid pressure differential control for gas defrost

2way diaphragm valves

When the solenoid coil is de-energized and energized, they function as adjustable pressure regulating devices which modulate to maintain a predetermined pressure drop across the valve 

Angle style construction eliminates the need for an elbow fitting at the liquid header

Extended ends for easy installation

Eliminates the need for an external check valve and the associated piping needed on supermarket racks with gas defrost.
