Rising Stem, Double Wedge Disc

Fig 2228

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. Male-female construction. Adjusts readily to taper seats, sturdy collar strengthens disc-stem connection.

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.
