Check Valves are widely used for both sanitary and industrial applications to prevent backflow of product. Once the product flow stops, the ball rolls back to the seat at the inlet, preventing backflow. Ball Check Valves are commonly used with liquid products. Sping Check Valves are designed to assist closure pressure to create a positive shutoff. They are commonly used with liquid products as well. Both valves are offed with clamp and weld ends. Other connections are available upon request. Sizes range from 1" through 3" in T316 stainless steel.
