Valves for ethylene production SGV

Transfer Line and Decoke Line Isolation Valves, SINGLE GATE-Plate Design

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

The Single Gateplate type Gate Valve has a higher tightness and subsequently a higher safety level than other designs. It provides a permanent contact with defined, positive sealing force between the upstream- and downstream valve seats and gate plate by means of precise, mechanical adjustment independent of the medium flow direction.

Key features

Double Block and Purge performance within one valve body
No springs in use
No lift-off in case of back-pressure.
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
