Overview

VB Valves manufactures the full range of Gate Valves, which are ideal for bi-directional, low friction flow and shut-off as per international standards. Due to the flow characteristics of the wedge to seat design, Gate Valves are always operated in the full close or full open position.

VB Valves offer wide range of sizes in gate valve right from 2 to 24 (DN- 50 to DN -600) and pressure rating ranges from #150 to #2500. Higher pressure rating and bigger sizes can also be provided.

  • Seat is hard faced, ground and lapped to a very smooth finish.
  • Wedge is ground and lapped to a very smooth finish and optimally guided to prevent dragging and seat damage
  • Rising stem with trapezoidal treads and burnished finish for best in class gland sealing
  • Body and bonnet joint accurately machined
  • One-piece bonnet up to DN 300 for better alignment and fewer parts

Features

  • Flanges: Standard as per B16.5, and others as per BS, AWWA, EN, DIN Etc
  • Raised face with serrated finish (125-250 AARH) Other options available
  • Seat rings are seal welded with body to eliminate leakage and accidental loosening of the seat ring
  • One piece bonnet design
  • Flexible wedge/Split wedge with balanced design to minimize vibrations due to flow
  • Highly finished seat face with lapping
  • Rising stem trapezoidal threads and burnished finish
  • Pillar yoke construction for easy access to bonnet & packing rings for maintenance
  • One piece cast flexible wedge that minimizes stress concentration

Benefits

  • Thoughtful design delivers accurate performance
  • Automatically adjusts the slight misalignments caused by pipeline deflections & thermal deformation
  • Manufacturing with advanced processes for best results and longevity
  • Superior strength due to Single piece forged Stem
  • Minimum torque due to flexible wedge/Split wedge construction

Overview

VB Valves manufactures comprehensive range of forged steel Gate Valves, which are ideal for critical as well as standardized applications across industries where the pressure requirement is relatively high.

Forged Steel Valves are available in forged carbon steel, alloy steel and stainless steel materials with sizes ranging from 15 mm to 50 mm. These Valves are available in full port and reduced port type openings, and typically available in socket weld ends. Flanged or butt-weld ends can be provided in case of specific requirements. All valves are manufactured in accordance with the latest industry standards.

  • Seat rings are a part of Valve trim. These are flared into the Valve body and fitted into place, thus forming sealing with body. Seating surfaces are machined, ground & lapped to obtain maximum sealing efficiency.
  • These Valves are available in full port and reduced port type openings.
  • Seat rings are flared into the Valve body and fitted into place, thus forming sealing with body.

Features

  • Body and bonnet is designed as per the dimensional requirements of standards such as API 602, ISO 15761 and ASME B16.34.
  • Bonnet is having integral backseat and consists of stuffing box, designed as per specification of API 602 and ISO 15761.
  • Stem has double start ACME Thread for smooth and fast operation

Benefits

  • Smooth and fast operation.
  • Manufacturing with advanced processes for best results and longevity
  • Excellent sealing efficiency
