Get Your Backflow in Check
When a check valve is needed to prevent backflow,
Has a complete line-up, including the U-ideal check valve with self-closing disc, horizontal swing, sliding disc, silent check and Y pattern. Ask us how to spec the right check valve, or get catalogs, chemical resistance guides and submittals. You're always guaranteed of superior quality, service expertise and the u-ideal warranty.
Solder, threaded, flanged, wafer, grooved end connections
End connections for Class 125, 150, 200, 250, 300
Bronze, ductile iron, iron body, bronze mounted trim (IBBM), and corrosion resistant materials
Cast Ductile and Alloy Iron Check Valves for use in commercial and industrial applications. Services include: Hot and cold water, HVAC, steam, oil and gas, limited chemical, petroleum refining and production.
Check valve(back pressure valve, swing valve, one-way valve): A valve that closes by fluid pressure to prevent return flow (Also called nonreturn valve), A check valve is a mechanical valve that only permits water flow in one direction. There must install check valve where don't allow fluid flow back such as compressor or pump outlet.
For low pressure medium and nominal diameter
If 1200mm>DN>200mm, select butterfly check valve or diaphragm.
If require pipe small water hammer or no water hammer, better select slow-close type swing check valve and low-close butterfly check valve.
