Globe valves can be offered with stellite seat

VOLFRAM make Valves are tight sealing, easy operation, regulation valves for liquid and gaseous fluids over a wide range of line pressures and temperatures.

Globe valves are of outside screw & yoke (OS & Y) and with bolted bonnet construction. The outside screw ensures easy lubrication and prevents corrosion and erosion by line fluids.

Features Globe Valve:

  • Body & Bonnet: The body is designed for strength to meet the operating conditions and contoured to minimize erosion and resistance to flow. The bonnet is provided with renewable back seat arrangement.
  • Disc & Stem: The disc provides a fine bearing on a taper seat for tight sealing over wide range of differential pressures. As the seating between disc and body seat is a narrow line contact, tight sealing can be achieved even if any foreign particle gets stuck to the seating area. The disc and stem are held together by a disc nut with allowance for disc to swivel. The disc nut is tack welded to prevent loosening in service.
  • Body & Seat Ring: The seat ring is seal welded to provide a bubble tight joint.
  • Back Seat Arrangement: The back seat is designed to relieve back pressure on the stem packing when fully seated.
  • Seating Surface: Globe valves can be offered with stellite seat, if specified. Stellited seat ring provides increased resistance to ware, abrasion and erosion of the sealing surface.
  • Gland Arrangement: The stuffing box holds a minimum of 6 packing rings to enhance gland tightness and increases the life of packing rings.
  • End Connection: Standard valves are offered with flanged ends (butt weld ends provided on request) to the following standards:
      - Flanged      :ASME B 16.5 Raised Face
      - Butt Weld   :ASME B 16.5 to suit the corresponding pipe schedule
