High-Pressure Regulators
For pressure reduction from high-pressure gas sources and cylinder systems.
Precision. Reliability. Innovation.
Gas pressure control
Pressure Regulators Engineered for the Application
Reliable pressure reduction and control for industrial gas distribution, high-purity applications and point-of-use systems. PES selects regulators according to gas type, inlet pressure, required outlet pressure, flow, purity, materials and end-use requirements.

Pressure fundamentals
What Does a Gas Pressure Regulator Do?
A pressure regulator reduces and controls gas pressure from an upstream source to a controlled downstream pressure suitable for the next stage of the gas system or the end-use equipment.
The regulator is selected according to where it sits in the gas architecture and what pressure and flow conditions exist at that point.

Regulation Across the Gas Supply System
PES selects regulators according to gas type, inlet pressure, required outlet pressure, flow, purity, materials and end-use requirements.
Line Regulators
For secondary pressure control within industrial, laboratory and point-of-use distribution pipelines.
Single-Stage Regulators
For applications where one pressure-reduction stage meets the inlet variation, stability and process requirements.
Two-Stage Regulators
For applications requiring pressure reduction in two stages under changing inlet conditions.
Precision / Low-Pressure Regulators
For laboratories, instrumentation, laser systems, specialty gases and sensitive process equipment.
Point-of-Use Regulators
Compact pressure-control arrangements installed close to production machinery, brazing stations or laboratory equipment.
What Determines Regulator Selection?
Exact specifications are selected from the applicable regulator model and manufacturer datasheet. PES reviews the engineering fields below rather than treating the regulator as an isolated component.
Gas type
Materials, seals and cleaning requirements may vary by gas.
Inlet pressure
The regulator must suit the actual upstream pressure.
Outlet pressure
The pressure range must match the downstream process.
Flow
Required flow must be considered alongside pressure control.
Pressure stability
Standard, precision or two-stage regulation may be appropriate.
Material compatibility
Wetted components must be compatible with the gas.
Connection
Connection type and size must suit the pipe, tube or panel.
Installation location
Source, manifold, pipeline, panel and point-of-use locations create different requirements.

From component to system
Integrated Into Complete PES Gas Systems
Prema Engineering Services does not treat the regulator as an isolated component. We evaluate how it interacts with the complete gas system.

End use
Regulator + Gas Panel
Where required, PES assembles regulators with valves, gauges, filters and associated components into a coordinated gas-control panel. Final configuration is selected according to the application.
Regulator + Brazing Station
The regulator is one part of a complete point-of-use gas system. PES can engineer the complete arrangement around the brazing process, equipment interface and operating requirements.
Assembly, Testing & Commissioning
Assembly
Regulator integration into manifolds, panels and point-of-use assemblies.
Testing
Appropriate pressure, leak and functional testing according to equipment and system requirements.
Commissioning
Verification of the installed system before handover.
