Valves


Bolted Bonnet:

Flowgain Valves offer various range of Industrial Valves like Gate valves, Globe Valves & Check Valves in Bolted Bonnet. Our Valves are supplying to reputed industries like Power & Plant, Airports and other Engineering Sector.

The Gate/Globe & Check Valves are in bolted bonnet construction flanged/socket connection and available in various pressure classes from 150 to 300, in a variety of materials and end-connections.

Gate Valves/ Sluice valve:

Bonnet construction in a gate valve is pressure seal bonnet. Gate valves may have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, gun metal, stainless steel, forged steels.

1" to 12"
ASME class 150 to 300

Important Features:

  • Uniform and precision casting and machining for body and bonnet.
  • Body parts are casted and machined in straight direction without recesses to counter resistance to flow, turbulence and erosion.
  • Guide slots in the wedge together with body and close contact with stem provide better contact and smooth operation.
  • Welded seat ring eliminate problem of leakage due to path between seat ring and body.
  • One-piece construction for stem provide long service life, smoother operation

Globe Valves:

For regulating flow in a pipeline, Globe valve is used. Globe valve is having movable disk type element and a fixed seat in a body. It is operated by screw rotation with the help of plug mounting on stem.

Salient Features:

  • Designed to ASME B16.34.
  • Body made of superior strength forgings and optional cast steel.
  • Non-rotating stem and uniform seating.
  • Casting of Body and Bonnet is with uniform sections, precision machined.
  • Body seat is hard faced to eliminate leakage path between seat ring and body.
  • Floating stem-disc connection guided plug-type disc.

Check Valves/Non-return Valve:

Check Valves is a mechanical device , which allows fluid to flow in only one direction.

BS 1868
Wafer, Flanged connection
Pressure rating- ASME Classes 150 – 300
2" to 12"

Salient Features:

  • Low flow resistance and low disc erosion due to full swing.
  • Casting of body and bonnet is with uniform sections, precision machined.
  • Internally-hinged disc.
  • Free disc rotation to avoid wear.

Forged Steel Valves:

Flowgain Valves offer various range of forged steel valves like Gate , Globe & Check Valves in forged construction to suit the requirements of clients. Flowgain forged steel valves conform to ASME B16.34 and the range comprises Pressure-seal Gate, Globe & Check Valves in ASME classes up to 300.

GATE VALVE

Designed & manufactured to API 602/BS-5352. Tested to AP- 998/BS-5146. Outside screw and yoke type bolted bonnet construction Body and bonnet made from high quality forgings in class of 300 and above. These valves are accurately machined Gate and seat rings with mirror finished seating surfaces as one of the feature to assure leak tightness Wedge. These are accurately guided throughout its travel in machined guide ways in body. Back seating surfaces provided integral to bonnet.

GLOBE VALVE

Designed and manufactured to BS-5352. Tested to BS-5146 boy and bonnet made from high quality forgings. Taper Plug type disc of globe valve and seated screwed seat ring with perfect matching of mating parts to assure leak tightness. Design flow passages to minimise pressure losses and erosion.

CHECK VALVE

Designed and manufactured to BS-5352 Tested to BS-5146. Plug type disc in taper design and with renewable seat ring for perfect seating assure leak tightness. Bush guided piston assuring accurate return to seat ring to achieve high leak tightness. These are designed for flow passages to minimise pressure losses.

Pipeline Ball Valves

Metal-seated:

Flowgain Valves offer metal-seated trunnion-mounted Ball Valves confirm to API 6 D standard. These valves are available in ASME classes from 150 to 300, in 2-piece and 3-piece construction, both in bolted and welded constructions.

Salient Features:

  • Stem sealing arrangement for better operation
  • Vent and Drain arrangement
  • Fire-safe to API
  • Trunnion Arrangement from inside
  • Double Block and Bleed

Butterfly valves

Wafer Type:

Flowgain Valves offers a wide range of Wafer-type Butterfly Valves.

A butterfly valve is a valve which is used for isolating or rflow. The wafer style butterflyegulating valve is designed to prevent backflow in systems designed for unidirectional flow in less space. Mould These valves are available in a variety of body configurations/ materials in PN 16 and PN 10 in sizes up to 400 mm.

Salient Features:

  • Perfect seating Assured sealing to atmosphere
  • Low force for operation
  • Longer service life
  • Design for easy installation
  • One-piece Shaft of blowout proof type

Flanged Type:

Flowgain Valves offers Flanged Butterfly Valves. These valves are of casted and in fabricated body for reliability. A unique feature of the valve is consistent sealing over a wide range of pressures. The valves are offered in classes PN6 to PN16 and sizes up to 16 inches in a variety of materials to suit various applications in utility, power plants, process plants, and water distribution systems.

Salient Features:

  • Self-lubricating bearings
  • Bi-directional flow
  • Offset disc
  • Self-energizing 'Autoseal'
  • Welded and in casted construction
