Sanitary Stainless Steel Check Valve Clamped End

Check Valves are widely used for both sanitary and industrial applications to prevent backflow of product.
Ball Check Valves are designed to allow full product flow during processing. Ball Check Valves are commonly used with liquid products. Air Blow Check Valves are designed to evacuate lines of product or CIP solutions. Once the product flow stops, the ball rolls back to the seat at the inlet preventing back flow.
Offered with Sanitary Tri-Clamp® or Sanitary Butt Weld ends. Other connections are available upon request
