Thanks to advanced technology we can state firmly that the BTV butterfly valves keep chemical fluids in your process piping and out of the environment. A self adjusting triple stem seal system assures no leakage to the atmosphere Viton seat energizer and concave PTFE liner design provide dependable consistent shutoff and closure torque. Spherical seat design of the disc and liner provides a 360° seal for long service life. The Viton energizer is isolated and protected in a machined groove of the valve body. The concave designed liner is recessed into the valve body and this reduces the possibility of torn liners due to cold flow into the valve waterway. Optional available: UHMWP and Durlon II and PFA-conductive liner materials.
