The project in context

Technology in its operating context.

Supply of self-acting pressure regulators for a petrochemical plant. The control valves were complemented by associated spare parts. This control principle uses the pressure of the process medium to operate the valve and maintain the required local pressure conditions in a pipe branch.

Scope of work

  • Pressure control valves
  • Associated spare parts

Execution

The project combined pressure-regulator preparation, inspection packing and subsequent distribution documentation in 2022–2023.

Pilot-operated pressure regulators

The technical scope included EMERSON EZR-1270 regulators with six-inch, Class 300 RF connections. Pilot operation uses the process-medium pressure to control the main valve.

The November 2022 inspection packing schedule lists four assemblies arranged in two pairs. Service parts were allocated to each pair by catalogue number.

Service parts and distribution stages

Spares included O-rings, gaskets and other sealing rings for the specified regulator versions. Preparation included allocating accessories separately to the valve groups.

Subsequent 2023 shipping documentation records a distribution stage to the Middle East, including spares for two years of operation.

Outcome

The reference scope comprises pressure-regulating valves with a corresponding set of service sealing parts.
