Brass service valve for split AC and refrigeration systems. Bar-stock brass body, ODF solder connections. With charge port for vacuum pumping and refrigerant charging. Max working pressure 4.2MPa (4.83MPa special square body). Temperature range -30°C to +120°C. Compatible with R22, R134a, R407C, R410A, R32.
Our Brass Service Valve is installed on the liquid and suction lines of split air conditioners to connect indoor and outdoor units. It allows technicians to close the inner passage for system isolation, and the integrated charge port enables vacuum pumping and refrigerant injection during installation and maintenance.
Constructed from bar-stock brass for high tensile strength and excellent stress corrosion resistance, it handles low pressure drops and is compatible with all common HCFC and HFC refrigerants. Available with or without charge port.
