Valve Balls

Located in the fluid chamber, balls serve as check valves, regulating the flow of the fluid being pumped. Typically sat on top of the seats, they function to prevent backflow when the diaphragm cycles. As the diaphragms move, they create alternating pressures within the fluid chambers, the ball check valve on the higher pressure side will open, allowing fluid to flow through the pump.

Over time, balls will wear due to factors such as abrasion, high pressures, extreme temperatures and more. Choosing the correct material for your product as well as regular inspection and replacment of damaged or worn balls can help mitigate the risk of failures.
