Product Description

Spring loaded, globe style lift check valve ASME Class 800 may be installed in horizontal and vertical piping applications.

Features

  • Disc is spring loaded for positive closure in any position.
  • The disc is hardened, ground and lapped, to ensure leak free sealing over the valve’s full pressure temperature range.
  • Seat is overlaid with Stellite or equal hardfacing.
  • The integral seat hardfacing is overlaid directly onto the body base material, eliminating any possibility of leakage behind the seat.
  • Flat, precision machined and lapped seating surfaces eliminate damage from high impact seating.
  • All internal surfaces are accurately machined to provide maximum performance.
  • Socket weld ends standard.
  • Standard body and bonnet materials are carbon steel (ASME SA105).
  • Code compliance with ASME 16.34 and the ASME boiler and pressure vessel code, Section I.
