Valves for ethylene production

Transfer Line and Decoke Line Isolation Valves, Double Disc Design

In the field of Ethylene Production, VCL offers Transfer Line and Decoke Line Isolation Valves tailored to your needs.

The Double Disc Trough Conduit type Gate Valve has a higher tightness and subsequently a higher safety level than other designs. It provides a true double isolation and purge capability within one valve body. To achieve the same functionality with other valves, two valves installed in the same line and an additionally purging of the space between the two valves are necessary.

Key features

  • Double Disc Technology provides positive, tight shut-off by means of active sealing force when shut
  • True Double Block and Purge performance within one valve body
  • Special valve-body design to avoid unequal seat deformation provides :
        – higher tightness (20% less steam leakage)
        – less deformation of the connecting flanges
        – less stress to the valve-body welding- seams
          > better fatigue performance
  • Open throughway without flow restrictions
  • in open position
  • Electrical, hydraulic or pneumatic options
  • available for valve actuation
  • Valve design according to customer demands and licensors/customers specifications

Typical Figures

  • size from 10” (250 mm) up to 58” (1450 mm)
    operating temperature up to 525°C
  • operating pressure up to 16 bar(g)
  • actuation: electric, pneumatic or hydraulic

Other sizes, design features and / or operating features are available on request.
