BuTech O-Ring Check Valve FPSC8

The O-Ring Check Valves reliably prevent backflow where leak-tight shutoff off of liquids or gases is required. The standard construction uses a Buna-N o-ring with a temperature range of -65° to 250° F (-54° to 121° C). The O-Ring Check Valve is also available with the following O-rings: Viton, Teflon and Kalrez.
