Piston Check Valve

Stop Backflow, Not Performance: Freture Techno Piston Check Valve.

We are leading Piston Check Valve manufacturer in Mumbai, India. A piston check valve, unlike some check valves with swinging flappers, ensures smooth operation and minimal pressure loss in pipes. This automatic valve uses a guided piston to control flow direction. When fluid flows in the desired direction, the piston is lifted, allowing passage. If the flow tries to reverse, pressure forces the piston down to seal the valve.

This innovative design from Freture's piston check valve minimizes resistance and pressure drop, even with frequent flow direction changes. Furthermore, it incorporates a spring mechanism, making it ideal for vertical installations and applications requiring additional closing force. The robust construction guarantees dependable performance for years to come.
