Description

Spring check valves are designed to prevent changes in the direction of flow of the working medium in the pipeline in the opposite direction. Operating principle: blocking the reverse flow of the medium is done by pressing the soft seal of the valve shutter to its seat under the action of a spring and the pressure of the reverse flow. The valve is opened by a pressure difference in the flow of the medium in the desired direction, while the valve shutter moves, compressing the spring.
