ANSI 150LB API6D Flanged Gate Valve , 4 Inch OS and Y Gate Valve

Description:

 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 trims.

 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 class.

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 motor operators.
