Henlem butterfly valves are offered to Petroleum Refineries, Chemical Processing Plants, Power Generating Plants, and and other processing application throughout the world.
Henlem butterfly Valves are designed, engineered and manufactured capable of closing with zero leakage. The precision seat and seal are machined at an offset angle creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling. This design provides repeatable long-lasting zero leakage shut-off.
