Globe Valve

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 tapered seat for tight sealing over a 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 the 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 satellite seat if specified. Stellited seat ring provides increased resistance to wear, 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
