Custom Product Attributes Refrigerant Cylinder Non-Return Valve
Product Description
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.
