Non-rising Stem, Single Wedge Disc, Union Bonnet
Fig 2230
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.
Seats
Renewable. Precision tapered integral seats.
Discs
Renewable nickel alloy. Thread in disc engages stem thread, moving disc as stem is turned.
Bonnet
Sizes 2″ and smaller have union bonnet connection; 2 1/2″ and 3″ have bolted bonnets.
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
Stuffing boxes are deep and valves are repackable under pressure when wide open. Back seats above stem threads make scale formation unlikely and provide a tight seal.
Hexagon head gland
Permits the use of a light wrench to easily loosen and raise gland.
Non-slip handwheel
Insures tight closing.
