Buy Stainless Steel Ball Valve

Ball-check valves use a free-floating or spring loaded ball resting in a seat ring as the closure element. Upon reverse flow, the ball is forced back into its seat preventing backflow. These valves are good for most services. They can even handle fluids that produce gummy deposits. Since the disc is free to rotate wear is distributed evenly and this all helps to keep the valve seats clean.

Check valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. The mechanics of check valve operation are not complicated. Most check valves contain a ball that sits freely above the seat, which has only one through hole. The ball has a slightly larger diameter than that of the through hole. When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. But once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow.

Ball valves provide tight shut-off and characterizable control. They have high range ability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves.
