Valve retention 1/2 of 3 way for compressor - Aignep

Valve retention (non-return) for compressor with male thread 1/2 of 3 way, body made of brass EN 12164 CW614N (high tensile strength). The main function of this valve is to guarantee the air flow in one direction only, preventing the compressed air from returning to the compressor when it is inactive, becoming an essential element of protection that contributes to the durability of the internal parts of the compressor by maintaining the air pressure in the correct direction.


The valve retention for compressors is autonomous operation, as it is driven by pressure difference in the system, through a tube connected to the valve that communicates with the pressure switch to stop the compressor when it reaches the set pressure. The connection system of the pressure switch and the manifold is made by means of nuts, included in the supply with the valve.
