Gate Valve
Gate Valve
Product Code : 13
Product Description

The Gate Valves we offer are substantial and of yoke types. Enclosed with external screws, bolted bonnets, ascending stems and non ascending hand wheels, these valves are of optimal quality. The consecutive and bore designs of these products insures minimal turbulence, less eroding and are impedance to flow. The most precocious design these products incorporate result in their eventual dependability and economic flow control. Available in a wide orbit of sizes and weights, these are ideally appropriate for advanced pressure and temperature as well as for variety of fluids.

  1. Body: Body is formed with inbuilt flanges, which meet operational premises. Bore as per API 600, the preciseness of the body of products instruments unimpeded flow, less erosion and decreased pressure drop.
  2. Bonnet: The Bonnet is as formed with intrinsic yoke of size 8". All bonnets are machined in precision with strict tolerance as the body for perfect coalition of the base and wedge center. The body bonnet joints are machined well for the flat face or tongues. The groove joints are reckoning upon the pressure evaluation.
  3. Seat Ring: Renewable seats are hard featured and are machined to lessen the wear. These rings are seal united to the body. Integral Seats are furnished for Austenitic Stainless Steel Valves. The high quality deposits and other difficult facing alloys are confident by the usages of harnessed preheating. The automated plasma arc are featured for facing and controlling the cooling action.
  4. Wedge : The one piece flexible wedges, with debased stem to wedge connection, gives straight alignment of pairing surfaces. The flexibility recoups for seat damage. Ideal for procedures with big temperature variations, the Solid wedges are also available on specific requests for their various processes. Derivative hardness of 50 BHN is retained between wedges and seat rings.
  5. Stem: The non rotating stems with accurate ACME threads are machined and brightened to make a mirror finishing of 0.8 microns ideal for low torque. The Tee-head connections precludes distal stress on the stem.
  6. Stem Nuts : The stem nuts are precisely machined and give an accurate control over wedge points.
  7. Gland: Two piece glands are given for ease of alinement. These also apply equal pressure level on the packing avoiding the connection of stems.
  8. Gland Flange
  9. Packing: Die Shaped Grafoil rings with top and bottom twisted rings gives eventual sealing for a big scope of service. Assuring extended packing life, it avoids corrosion on stem.
  10. Gasket: Helical coiled metallic gaskets with Grafoil.
  11. Yoke: Built-in up to 8" for amended alinement and less parts.
  12. Back Seat bush: These bushes are precisely machined and help for the substitution of packing at opened points.
  13. Retainer
  14. Eye Bolt & nut: Swing form eye bolts are provided for comfort in replacement of the stuff.
  15. Body Stud & nut
  16. Yoke Stud & Nut
  17. Solid Groove pin
  18. Hand Wheel: Hand wheels are in regulation up to 10". Gear operators can also be provided on special requests.
  19. Hand Wheel Nut
Gate Valves are competent for all services in different centers. These are executed in Oxygen service, Hydrocarbon service, Hydrogen service and NACE applications. Other facilitative features like bleed holes, lantern ring, live loading, purging lines and many other exclusive features are available on request. Gear operators are available for 12" and even higher than this comes under the standard of company.
