Overflow Valve
The overflow valve is suitable for occasions with a large range of cooling capacity requirements. It is a valve designed to prevent system pressure fluctuations caused by low flow rate or low density. For the control of evaporation pressure, condensing pressure, exhaust pressure, etc., it has three application functions: relief valve, check valve and stop valve.
Applicable medium: R12, R22, R502, R134a, R404A, R507, R717, etc

● All parts of the valve body are made of low temperature steel, suitable for all common non-flammable refrigerants, including ammonia, fluorine, etc.
● It has three application functions: Overflow valve, check valve and stop valve.
● Adopting butt welding without flanges, so as to reduce the risk of system piping leakage.
● Designed to prevent disturbances caused by low flow rates or low density, ensuring system stability.
● Wide range of pressure regulation, 2bar-8bar.
● It can be used to control evaporation pressure, condensing pressure, exhaust pressure, etc.
