A check valve is an important component of a piston compressor that ensures the compressor starts without back pressure and unloads when it stops. It is usually located after the discharge pipe and before the compressed air tank. In a spring-loaded check valve, the shut-off element opens only when the pressure of the compressed air is able to overcome the resistance of the spring pressing the shut-off element of the valve against its seat. This type of air check valve can operate in both vertical and horizontal positions.
Check valve with external threads for piston compressors: 1/2" thread for connection to the receiver, M16 for connection to the discharge tube or hose, 1/8" conical external thread for connection to the discharge tube ⌀ 6 mm., used in many compressor models from various manufacturers, such as MECAFER, FINI, NuAir, and BLACK & DECKER.
