Series 36/37


  • Manufacturer: EMERSON
  • Valve Type: Butterfly Valves - Rubber Lined / High Performance / Triple Offset
  • Sub-Type: Keystone Butterfly Valves
  • Blow-out resistant shaft is standard on all valves for increased safety.
  • Unique packing design allows for use in pressure as well as vacuum without modification or special assembly.
  • Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure.
  • Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks.
  • Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
  • Extended neck allows for 50 mm (2") of pipeline insulation.
  • Integrally cast mounting pad provides direct mounting of actuators eliminating the need for costly brackets and couplings.
  • Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.

Details

Primarily designed to meet the stringent requirements and safety levels of the oil & gas industry, this high performance butterfly valve is available in a range of sizes, from 3 inches to 24 inches (DN 80-600). This makes them ideally suited for a host of applications, including firewater, hydrocarbons, cargo handling, bilge and ballasts and utilities, just to name a few.  Manufactured to ASME 150 and 300 standards, the Series 36/37 Double Flanged Butterfly Valve features a soft polymer seat. Customers can specify PTFE, RTFE or UHMWPE seats, depending on their application and the performance characteristics required.
