These strong, heavy-duty, gas-powered solenoid valves are designed to control the flow of refrigerant in large commercial and industrial applications.
They require no pressure drop to operate and have no internal bleed to suction.
A dual pilot solenoid valve assembly introduces a high pressure refrigerant source which closes these valves. To open valves, pressure is bled-off back through the low pressure bleed pilot valve and upstream line pressure plus the spring causes the valve to open wide.
