Rising Stem, Solid Wedge Disc, Union Bonnet
Fig 3127
Designed for rugged service applications, with maximum resistance to distortion produced by internal pressure.
Bodies
Full, cylindrical design for maximum strength, made of corrosion resistant Steam Bronze. Extra length pipe threads prevent pipe ends from jamming against seats.
Bonnets Union Design
Heavy bonnet rings are octagonal to provide a firm wrench hold and increase strength.
Stems
Resistant 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.
Repacking
Valves are repackable under pressure when wide open. Stuffing box and packing nut are exceptionally deep to insure firm thread engagement when fully packed. Back seats above stem threads make scale formation unlikely and provide a tight seal.
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.
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.
