Industrial Pressure Regulators

Select a regulator by matching the required inlet/outlet pressures, flow rate (CV or SCFM), media compatibility (air, gas, liquid), connection size and type, and materials for the operating environment; verify pressure range and whether you need single-stage, two-stage, or back-pressure regulation

Choose body materials like stainless steel, brass, or carbon steel depending on corrosion and strength needs, and select seals (EPDM, Viton/FKM, PTFE) based on the media's chemical compatibility and temperature range to prevent swelling or degradation

The CV (flow coefficient) indicates how much flow a regulator allows at a given pressure drop; ensure the CV meets your peak flow demand to avoid pressure drop and instability, and size the regulator for expected maximum flow rather than only steady-state conditions

Look for compliance with relevant standards such as ASME, ANSI, CE, ATEX for hazardous atmospheres, and any industry-specific certifications (e.g., NACE for sour service) to ensure safety and suitability for your application

Perform periodic inspections for leaks, diaphragm or seal wear, and proper spring adjustment; follow manufacturer-recommended service intervals, replace worn internal parts, and bench-test setpoint and response under simulated load conditions after maintenance

Yes—pilot-operated and two-stage regulators provide tighter, more stable control for precision applications, while direct-acting regulators are simpler and suitable for lower-flow or less-critical pressure control where some fluctuation is acceptable

Industrial regulator prices vary widely based on material, size, flow capacity, precision, and certifications; expect budget options at lower ranges, with average-category products commonly in the low-to-mid hundreds, while specialty stainless steel or certified models cost more
