Hattersley butterfly valves are compact quarter-turn valves with an elastomer-lined body for a tight seal. Available in wafer or lugged designs, they can be operated by lever or gearbox, with linings of EPDM or Nitrile rubber based on service conditions. While primarily for on-off service, they can also handle non-critical throttling. A quarter turn is sufficient to open or close the valve. Hattersley also provides high-performance butterfly valves designed for superior shut-off and regulation, suitable for high pressure and temperature conditions beyond standard concentric disc valves, ensuring exceptional performance and reliability.
