The Pressure Reducing Station (PRS) is specifically designed to eliminate hazards associated with unregulated high-pressure steam systems—such as pipe rupture, valve seat erosion, water hammer, and system overload. These failures can lead to costly downtime, safety risks, and damage to downstream equipment.
To address these challenges, the PRS delivers precise and stable pressure regulation while maintaining thermal equilibrium throughout the downstream process. Its design centers around a pilot-operated Pressure Reducing Valve (PRV), engineered for high responsiveness and accuracy. Integrated multi-stage noise attenuation and anti-cavitation trim ensure smooth pressure drop across stages, significantly reducing turbulence, vibration, and noise—key factors that lead to equipment wear and failure.
This advanced configuration is capable of throttling pressures from 150 bar to as low as 5 bar with ±1% accuracy, ensuring consistent output even under fluctuating upstream conditions. The result is a highly reliable, maintenance-friendly system that enhances process stability, protects critical assets, and improves operational safety across steam-intensive applications.
The pressure reducing station employs dual-seat pilot valves and dome-loaded actuators to maintain setpoints despite upstream fluctuations, while machined labyrinth discs dissipate kinetic energy to prevent cavitation damage. Its compact, modular design simplifies retrofitting into legacy infrastructure, making it a cornerstone of modern, resilient steam distribution networks.

A pressure reducing control station integrates a pressure reducing valve (PRV), instrumentation, and safety components to precisely regulate downstream pressure while ensuring system stability. It often includes features like bypass valves, safety relief valves, and gauges for comprehensive control.
Industrial Steam Pressure Reducing stations manage pressures up to 420 bar and temperatures exceeding 500°C, compliant with ASME B16.34.
Stations include safety relief valves or rupture discs set at 10–15% above the PRV’s setpoint, ensuring automatic bleed-off during failures.
Advanced pressure reducing stations use pilot-operated PRVs with damper valves or multi-stage trims to smooth spikes and respond to load changes in <2 seconds.
Multi-stage pressure reduction, anti-cavitation trims, and diffuser plates mitigate noise (below 85 dB(A)) in high PRS systems.
By maintaining optimal pressure profiles, pressure reducing stations reduce pump/compressor loads, cutting energy waste by 15–20% and extending equipment lifespan.
