Rising Stem Solid Wedge Flanged End
Fig 2157
Class 150 bronze gate valves are ruggedly designed for industrial and general service with steam, water, gas and oil.
Bodies
Flanged ends: Easy to remove from the line, an advantage when dealing with corrosive chemicals.
Discs
Renewable. Solid wedge discs: Accurately machined with disc-wing guides that conduct the disc to a firm, tight seat. Ideal for food processing lines and handling gummy substances where entrapment of line materials within the disc is undesirable.
Stems
Resistent to wear, corrosion and embrittlement. Long, accurately machined threads provide full thread contact. Heavy, disc-stem connection withstands wearing action when opening valve and prevents stem failure under strain.
Bonnets
Screw-in design. Provide strong, wide flats for a firm wrench hold.
Flanges
Conform to MSS 150 lb SP Bronze
Repacking
Valves are repackable under pressure when wide open. Stuffing boxes are deep and well packed. Back seats above stem threads make scale formation unlikely and provide a tight seal.
Seats
Integral. Accurately tapered to insure perfect seating of the discs.
Hexagon head gland
Permits the use of a light wrench to easily loosen and raise gland.
Non-slip handwheel
Insures tight closing.
