INTRODUCTION
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.
APPLICATIONS
These valves are ideally suited for low temperature applications to positively close suction lines, liquid overfeed and flooded evaporator gas return lines, as well as gravity liquid and gas lines for defrosting. Because they are gas powered, these valves operate reliably at low temperatures and even under viscous oil conditions. They are suitable for ammonia, R22, R134a, CO2 and other approved refrigerants.
