Atlas Copco non-return valve2906095900

Air compressor non-return valve is usually installed in important parts of the compressor, such as between the exhaust pipe of the host machine and the oil separator.Its main function is to prevent the pressure in the system from making the lubricating oil flow backward to the oil-air separator through the oil return pipe when the air compressor stops running, or to avoid the backward flow of the inhaled air when the system pressure is released.This kind of valve works automatically, under the pressure of fluid flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-weight of the valve flap make the valve flap act on the valve seat, thus cutting off the flow. Thus cut off the flow. Check valve check valve principle of operation only allows the medium to flow in one direction, and to prevent the opposite direction of flow
