Check valve duckbill, umbrella, ball

Molded and Ground Balls are rubber spheres of high dimensional accuracy, providing an effective and efficient check valve function to seal against hydraulic fluid, water or air. Duckbill seals are precision slit to create efficient and predictable one way sealing or pressure relief. Umbrella seals are tuned via dimensioning and material formulation to provide predictable lift/burst load and roll back.

Special Applications

Materials, break force, installation types vary with application requirements
