Valves for dehydrogenation

Wedge-within-Wedge type Isolation Gate Valves

In the field of Dehydrogenation, VCL offers Wedge-within-Wedge type Isolation Gate Valves tailored to your needs.

The Wedge–within-Wedge type Gate Valve is designed for extreme tight isolation under severe operation conditions of high temperature, unequal temperature distribution, high pressure and high line stresses. In addition its design allows a high frequency of operation and an easy, low-friction actuation in opening as well as in closing direction.

Key features

  • Double Disc Technology provides positive, tight shut-off by means of active sealing force when shut
  • Double Block and Purge or Double Block and Bleed performance within one valve body
  • High tightness, no jamming or blocking of the valve even under severe temperature differences by means of double wedge design
  • No wear of sealing surfaces due to axial pressing in closed position
  • Valve available in casted design as well as fabricated design, according to customer demands and licensors/customers specifications
  • Electrical, hydraulic or pneumatic options available for valve actuation

Typical Figures

  • size from 10” (250 mm) up to 80” (2000 mm)
  • operating temperature up to 700° C
  • operating pressure up to 10 bar(g)
