GASCAT gas pressure regulators for gas networks and industry

Gas pressure regulators play a central role in gas supply systems: they reduce the inlet pressure to the level required by the downstream network section or industrial process.

Requirements can vary considerably. Inlet pressure, outlet pressure, flow rate, control accuracy and required safety functions determine which regulator design is suitable for each application.

The GASCAT range offers various direct-acting and pilot-operated solutions, as well as safety valves.

A gas pressure regulator reduces a higher inlet pressure to a defined, lower outlet pressure.

When the inlet pressure or gas demand changes, the regulator adjusts its opening accordingly. This helps maintain the required outlet pressure within the specified control range.

Selecting a gas pressure regulator depends on the actual operating conditions of the pressure regulating station. Key factors include inlet pressure, required outlet pressure, and minimum and maximum gas flow.

Other factors include gas type, temperature, nominal size, pressure rating, required control accuracy and safety functions.

Depending on these requirements, direct-acting or pilot-operated GASCAT gas pressure regulators may be used.

In a direct-acting gas pressure regulator, the pressure being controlled acts directly on the valve’s regulating mechanism.

A pilot-operated gas pressure regulator also has a pilot system that controls the main valve. This design is suitable for demanding pressure conditions, high flow rates or applications with specific control requirements.

The appropriate design depends on the actual operating conditions.

High inlet pressures place specific demands on the design, materials and control behaviour of a regulator.

Special regulator series such as DOMUS are available within the GASCAT range for these applications. The specific configuration must be selected according to inlet pressure, outlet pressure and required flow rate.

A large difference between inlet and outlet pressure can significantly increase the demands on a gas pressure regulator.

Pilot-operated solutions such as URANO are available in the GASCAT range for these applications.

Additional safety functions may be required alongside pressure regulation.

Safety shut-off valves interrupt the gas flow when defined limits are reached. GASCAT offers several slam-shut valve series, including GIPS-FC, GIPS-L and TWIN-FC.

The required combination of regulation and safety devices depends on the system design.

GASCAT regulators and safety valves can be used in applications such as:

• gas distribution networks
• gas pressure regulating and metering stations
• gas transfer stations
• industrial gas supply
• high-pressure gas systems
• process plants
• energy and utility systems
