Check

The piston check valve is designed to ensure unidirectional fluid flow, preventing backflow in industrial applications where it is essential to maintain system integrity and protect equipment from damage caused by reverse flow.
Its compact design allows for installation in confined spaces while maintaining high sealing performance. The valve is equipped with a piston that moves under spring action, opening the passage under normal flow conditions and closing automatically when the flow changes direction.

The valve’s seal is ensured by an O-ring, which engages across two diameters to guarantee a hermetic seal and effective protection against leaks. Additionally, the PTFE seal operates in a sealing position, further improving corrosion resistance and ensuring excellent isolation in high-pressure applications and aggressive environments.

The piston check valve is an ideal solution for systems where safety and reliability are critical, offering extended service life and excellent performance even under the most demanding operating conditions.
