What is a Pressure Regulating Skid?

A Pressure Regulating Skid (PRS) is a modular, pre-assembled system designed to reduce and control gas or fluid pressure to a safe, steady, and required level before it enters a downstream process or distribution network.

It ensures that even when the inlet pressure or flow fluctuates, the outlet pressure remains constant and safe — protecting downstream equipment and maintaining process stability.

A Pressure Regulating Skid automatically adjusts and maintains gas or fluid pressure at a preset value, using valves, regulators, and control instruments — all mounted on a compact steel frame.

Typical components include:

1. Inlet & Outlet Valves – to isolate the system for maintenance or emergency shutdown.
2. Filter/Separator – removes dust, liquid droplets, or other impurities from the incoming gas.
3. Pressure Regulator / Control Valve – reduces high pressure to the desired outlet pressure.
4. Pressure Safety Valve (PSV) – releases excess pressure to prevent system damage.
5. Pressure Gauges / Transmitters – monitor inlet and outlet pressures.
6. Heater (optional) – prevents freezing of gas during pressure drop (especially for natural gas).
7. Flow Meter (optional) – measures the amount of gas passing through the system.
8. Control Panel (PLC / SCADA) – enables automation and remote monitoring.
9. Skid Frame – a steel base structure that holds everything together for transport and easy installation.
