Pneumatically actuated valves for gas processing

The project comprises 150 recorded on/off, shutdown and blowdown valve assemblies in a range of materials and pressure classes. Its documentation links valves, actuators, controls, functional testing and staged dispatch for an export project in the Middle East.

Staged valve and actuator supplies

Historical project portfolio; the documented invoiced stages were supplied by EMKO HOLDING s.r.o., company ID 04624688. MIS EUROPE s.r.o. also appears in dispatch records.

150 assemblies recorded in the project; the first documented completed stages cover 111 assemblies. The remaining 39 form a separately recorded final stage.

Scope of work

  • 150 assemblies in the technical scope; documented completed stages: 36 + 75
  • Valves from 1″ to 32″, pressure classes 150, 300, 600, 900 and 1500
  • Pneumatic actuators, controls, functional tests and export packing
  • The final 39 assemblies form a separately recorded stage

Execution

Assembly and inspection followed the individual duties in the technical schedules. Deliveries were divided into stages with their own inspection records, packing lists and commercial documents, allowing the completed lots to be identified precisely.

Configurations for different process duties

The technical schedules contain 79 ESDV, 30 SDV, 22 XV and 19 BDV assemblies. Of the 150 assemblies, 137 use trunnion-mounted balls and 13 use floating balls. The project scope covers connection sizes from 1″ to 32″, including reduced-bore configurations.

The specified pressure classes are Class 150, 300, 600, 900 and 1500. Body material variants include ASTM A350 LF2 low-temperature carbon steel, A182 F316/316L stainless steel and B148 C95800 alloy; selected configurations specify stainless weld overlay in the seat-pocket areas. Materials, seals and actuators are linked to the individual valve duty and process medium.

Assembly, controls and functional verification

The supply assemblies combine valves with pneumatic actuators and control components. The documentation addresses drawing interfaces, assembly identification and accessories, including stainless steel control-panel supports. Air reservoirs and fire-protection blankets are recorded for selected duties.

Inspection records describe checks of smooth movement, end positions and operating times, including the fail position on loss of control energy. Depending on the configuration, tests also covered solenoid commands, manual operation and partial stroke. The review included FAT reports, the inspection and test plan, and documentation for electrical components in hazardous areas where specified.

Documented stages and export packing

The first documented lot contains 36 assemblies. Its signed February 2022 packing list records 19 cases with a total net weight of 3,113.98 kg, including accessories. A second lot covers a further 75 assemblies, 40 cases and a net weight of 18,320.8 kg. An inspection release from May and a mechanical completion certificate from June 2022 are documented for this stage.

A further 39 assemblies form a separately recorded final stage with its own packing and test documentation. The total of 150 assemblies therefore represents the technical project scope; the completion and release records used in this case study relate to the first 111 assemblies.

Outcome

A technically varied valve package was managed by individual duty and delivery stage, with traceability to inspection records and export packing. For the first 111 assemblies, completion documentation can be linked to the corresponding invoiced stages.
