Rising Stem, Solid Wedge Disc, Union Bonnet
Lunkenheimer Gate Valves
Fig 2227
Lunkenheimer Gate Valves are 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 seat rings of Monel alloy in 1″ and larger sizes; integral seats in smaller sizes.
Discs
Renewable nickel alloy. Accurately machined with disc-wing guides that conduct the disc to a firm, tight seat.
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.
