Hattersley butterfly valves are compact quarter turn valves. The body is elastomer lined providing a resilient bubble tight shut off. The valves are supplied in wafer or lugged variants and may be lever or gearbox operated.
Linings are EPDM or Nitrile rubber depending on the intended service conditions. Primarily recommended for on off service, they may also be used for non critical throttling applications. Only a quarter turn is needed to fully open or close the valve.
Hattersley also offer a range of high performance butterfly valves, developed for high integrity shut-off and regulation duties. This range is ideal where increased pressure and elevated temperature specifications are outside the normal operating parameters of concentric disc valves. The Hattersley high performance valves have enhanced features to provide impeccable performance and reliability.
