Stainless Steel Check Valves Highly Corrosion Resistant with PTFE Seals by SuperWhole Check valves are used to help direct flow in one direction. The stainless steel bodies and PTFE seals are highly corrosion resistant allowing these check valves to be used with a wide variety of fluids including, but not limited to water, oil, gas, air, light alkali's, acids, biodiesel, fuels and alcohols. Vertical check valves may be used for any application. They utilize a spring system which shuts the Disc closed when there is not enough pressure to hold it open by the operating fluid. Fluid pressure in the backwards direction will cause the valve to close to prevent backflow. Note: Check valves do not create a 100% seal against backflow like a ball valve would. If prevention of backflow is desired, two check valves should be used in series with each other. Any fluid which finds its way past the first check valve is unlikely to have enough pressure to pass through the 2nd. Check valves are 2-piece and servicable. They may be opened by unthreading at one of the port ends. SuperWhole manufactures pipe nipples following ISO 9001 standards for quality assurance. The company distributes pipe fittings in the United States and Canada. Package Included: 1 piece x Check Valve
