Butt Weld Motor Operated Resilient Wedge Gate Valve Carbon Steel
Gate Valves offer the ultimate in dependavle service for steam,
air, gas, oil , oil vapor and high pressure in stallations. All
have streight-though ports to assure minimum turbulence, erosion,
and resistance to flow. They are available in a wide variety of
1 . Body: Body is cast to provide liberal strength to meet
operating conditions and to permit unobstructed flow.
Turbulence,erosion and pressure draop are minimized.
Flanged End cast steel gate valves are vaailable in flanged end and
butt weld ends. All flanged and Butt Welding end valves are
designed to conform to ANSI B16.5 and ANSI B16.34.
2 . Intergral Yok & Bonnet: Some designs incorporate a two
piece bonnet and yoke. All bonnet assemblies are cast and finished
to the same exacting tolerances as the bodies for accurate
alignment of stems and ease of sealing. Bonnet joint varies from
flat face gasket-joint to ring-tye bonnet joint, depending on
3 . Seat Ring: Seat rings are seal welded to eliminate leak path
bhind rings for long trouble-free service. The Surfaces are
precision ground to fit accurately with the disc.
4 . Wedge: One piece flexivle wedge provides accurate alignment of
mating seating surfaces , so the valve can absorb piping strains
without leakage. Valves are also furnished with solid wege that
have proved successful in millions of applications.
5 . Stem: The T-head , disc-stem connection prevents lateral strain
on the stem for smooth, easy operation.
6 . Packing: Packing contains corrosion inhibitor to avoid stem
pitting. Stuffing box is deep, assuring long packing life.
7 . Gland: Gland is two piece ball type which exerts even pressure
on the packing without binding the stem.
8 . Handwheel: Can also be supplied with gear box, Pneumatic and
