Cylinder Regulators

Single-stage & two-stage pressure regulators for industrial gas cylinders

Cylinder regulators reduce the high and varying pressure from a gas cylinder to a safe, stable working pressure. Because cylinder pressure drops continuously during use, the cylinder regulator plays a crucial role in the reliability, safety and accuracy of industrial processes, laboratories and high-purity systems.

For engineers, the choice between single-stage and two-stage determines process stability. Two-stage cylinder regulators provide the most constant outlet pressure, even when the cylinder is almost empty.

GO cylinder regulators: models & specifications

The table below lists the most widely used GO cylinder regulator series, including single-stage, two-stage and high-pressure versions.

Fields of application

Industry

• Process installations and production
• Gas dosing and gas mixing systems
• Hydrogen, CNG and industrial specialty gases
• Welding and thermal processes
• Pilot plants & R&D systems

High-purity and specialty gas

Selection advice for engineers

Choose the right regulator based on:

• Single vs two-stage → simplicity vs stability
• Inlet pressure → type of cylinder or gas source
• Outlet pressure range → process parameters
• Material compatibility → corrosive, inert or specialty gas
• Flow requirements (Cv) → instrumentation vs process gas
