![]() ![]() If a ball check makes noise it is typically due to insufficient pump capacity or water hammer issues. Ball check valves are typically preferred for use in pumping stations as they are self-cleaning as the ball rotates during the operation and are vertically maintenance-free. Flomatic ® offers ball check valves that have Buna-N lined ball as standard and with corrosion-resistant phenolic balls for abrasive media. The ball moves up and down inside the valve depending on the flow and seals against the machined seat when no flow or reverse flow occurs and seals against the seat to stop the reverse flow. 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. When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve. ![]() Cost-effective solution to control valve and isolating zero leakage problems where the failure of the critical service valves are cutting production, increasing downtime and lost man hours. The ball has a slightly larger diameter than that of the through-hole (seat). Flotech Controls has provided valve and instrumentation solutions to all industry sectors in Australia, New Zealand and the Asia Pacific Region since 1991. Ball Check Valvesīall check valves contain a ball that sits on the seat, which has only one through-hole. Due to its simple flow efficient and virtually maintenance-free design the valve is commonly specified and used in submersible wastewater lift stations. For vacuum or anti-flooding valve application, a "floating" rather than "sinking" ball is used. The full-ported valve seat is uniquely designed allowing the ball to seat leak-tight without getting wedge into the valve seat. COMMITED TO QUALITY AND THE ENVIRONMENTįlomatic ® Corporation is a global manufacturer and distributor of Ball Check Valves.Ī Ball Check Valve is a simple and reliable valve with the only moving part to block the reverse flow, is a spherical ball.Automatic Control Valves – AIS Compliant MADE IN THE USA.Cycle Gard IV – Constant Pressure Pump Control VERY FLOW EFFICIENT.Flo-Trol CD-900 – New Sizes and GPM’s EXPANDED FLOW RANGES.We stock spring check valves in 2pc and 3pc. ![]() Our range of spring check valves have a stainless body and disc with parallel female BSP threaded ends. The force of the flow will allow the gate in the valve stopper to open to allow the desired flow. Air Release Valves – AIS Compliant NEW AIS COMPLIANT Spring check valves allow fluid to flow in one direction. ![]()
