Our team is very service oriented aiming to satisfy customers by:

  • supplying customised special valves
  • overhauling special valves of all brands
  • and supplying the respective spare parts.

This applies among others for:

  • Main transfer and decoke line valves for ethylene production plants
  • Slide, guillotine, goggle und vapour overhead isolation valves for FCC units
  • Coke drum isolation valves for coke production plants
  • reactor valves for propane dehydrogenation

Double Disc Gate Valves

  • Metal seated isolation valves typically in sizes up to NPS 100”
    (2 540 mm)
  • Different kinds of actuation available
  • Customised design
  • Proven design continuously optimised for safe and reliable operation in compliance with international standards such as EN 13445, ASME B16.34 and API 6D
  • Design for harsh environment e.g. MDMT lower than -40°C (104°F)
  • Double-block and purge functionality in one valve
  • Tight shut-off designed for zero leakage acc. to API 598 or ISO 5208

Typical applications include, but are not limited to transfer and decoke line valves for steam crackers,

coke drum unheading valves and further isolation valves for Delayed Coker units as well as

vapour overhead isolation valves in FCC units.

 

Double Wedge Valves

  • Metal seated isolation valve in sizes typically up to NPS 48” (1 220 mm)
  • Different kinds of actuation available
  • Customised design
  • Proven design continuously optimised for safe and reliable operation, in compliance with international standards such as EN 13445, ASME B16.34 and API 6D
  • Design for severe process conditions, e.g. process medium  temperatures higher than 600°C (1 112°F)
  • Double-block and purge or double block and bleed functionality in one valve
  • Tight shut-off designed for zero leakage acc. to API 598 or ISO 5208

Typical applications include, but are not limited to, high cycling and high temperature application such as propane dehydrogenation and isomerisation.

Valve Solutions for Steam Crackers

Isolation valves behind the pyrolysis furnace and their appropriate actions are typically involved in any scenario that

requires  the decoking of the unit and hereby a transfer performed by linked valves.

ZMK offers linkage solutions including

  • Mechanical or electronic linkage, both designed on the basis of thorough understanding of system dynamics
  • Enhanced safety features androbustness of design for reliable and safe operations
  • Consulting, services and upgrades of existing solutions
