The Air Conditioner Refrigerant Cylinder Non-Return Valve is a specialized fitting designed to ensure the safe, efficient, and reliable handling of refrigerants. Built from high-quality brass, this valve is engineered to prevent backflow during the charging or discharging process, protecting both the refrigerant cylinder and the HVAC system.
This non-return (one-way) valve is compatible with popular refrigerants including R22, R134a, R410A, R407C, and R32, making it suitable for a wide range of air conditioning and refrigeration applications. Its precision-engineered construction guarantees leak-proof sealing under high pressure, ensuring safety and system integrity.
By allowing refrigerant to flow in only one direction, the valve prevents contamination, reverse leakage, and system malfunction. It is widely used by HVAC professionals for maintenance, refrigerant recovery, and system installation. With easy installation through standard SAE connections, this non-return valve is an essential spare part for both residential and commercial air conditioning systems.
