Stable, safe pressure reduction for downstream process and combustion systems
Our Pressure Regulating Skids are engineered systems designed to reduce, control, and stabilise gas pressure for downstream process and combustion applications. These skids are designed for safe and consistent gas delivery and protect equipment and personnel from pressure fluctuations. Built using CRA’s process and combustion engineering expertise, pressure regulating skids integrate regulators, safety shut-off valves, instrumentation, and piping into a compact, skid-mounted package. Designed for continuous industrial service, they provide accurate pressure control, operational safety, and straightforward integration with upstream gas supply and downstream users.

What is a Pressure Regulating Skid?
A pressure regulating skid reduces, controls, and stabilises gas pressure between an upstream supply and downstream process or combustion equipment, protecting equipment and personnel from supply pressure fluctuations and over-pressurisation.
How it works
Gas moves through inlet isolation, pressure regulation, and independent overpressure protection before it reaches the downstream setpoint.
Gas enters through inlet isolation and filtration, removing contaminants before it reaches the regulator.
Pressure regulators step down and stabilise the gas to the downstream setpoint.
Safety shut-off valves and relief devices provide an independent protection layer, closing automatically if outlet pressure exceeds the safe limit.
Regulator runs are often duplicated in active or standby configuration, allowing maintenance or changeout without interrupting gas supply.
Instrumentation monitors inlet and outlet pressure continuously throughout operation.

Frequently Asked Questions
What does a pressure regulating skid do?
A pressure regulating skid reduces and stabilises gas pressure between an upstream supply and a downstream process or combustion system, and protects equipment and personnel from pressure fluctuations. Regulators, safety shut-off valves, instrumentation and piping are mounted on one frame so the pressure reduction stage arrives as a complete package. CRA engineers these skids using its process and combustion background, so the skid holds outlet pressure steady when inlet pressure or gas demand changes, and feeds burners, furnaces and process users with gas at the pressure they need.
What safety devices are included in a pressure regulating skid?
A pressure regulating skid includes safety shut-off valves and overpressure protection devices alongside the regulators themselves. The shut-off valve closes the gas supply if outlet pressure rises above its set point, and relief or monitor arrangements protect the downstream system if a regulator fails open. Instrumentation gives pressure indication and alarm signals to the plant control system. This combination of control and protection is what separates a regulating skid from a stand-alone regulator, and CRA sizes and selects these devices for the actual inlet and outlet conditions of each project.
Which applications use a pressure regulating skid?
Pressure regulating skids are used for fuel gas pressure reduction, combustion air and fuel gas supply, process gas pressure control, burner and furnace gas regulation and utility gas distribution. They also serve equipment protection and isolation duties and emergency pressure relief and shutdown, where a fast and reliable isolation of the gas supply is needed. CRA designs skids for continuous industrial service and matches each one to the inlet pressure, outlet requirement and duty of the application.
How is a pressure regulating skid sized?
A pressure regulating skid is sized from the inlet pressure range, the required outlet pressure, the gas composition and the flow range of the downstream duty. Regulator capacity and turndown, shut-off valve response and pipe sizing all depend on these conditions, so a generic valve selection does not work. CRA carries out the sizing, valve selection and system integration in-house and designs the skid for the full operating envelope, including start-up, low-flow and peak-demand cases.
What standards apply to CRA pressure regulating skids?
CRA pressure regulating skids are designed to the safety codes and industry standards that apply to the destination market and the application, covering the regulators, safety shut-off valves and piping. CRA's designs are aligned with API, ASME, ISO and IEC practice as relevant to each project, and the company is ISO 9001 certified through TÜV NORD. Process, mechanical and controls engineering are carried out in-house in Noida, so the standard set agreed for a project is applied across the whole skid.
