Regulators
Regulators are devices that control the pressure of gases and liquids. Centro carries a complete selection of regulators available to purchase online, including compress air regulators, FRL compressed air regulators, and air regulators. Our compress air regulators are designed to maintain a constant output pressure, even as the input pressure changes. Our FRL compressed air regulators are ideal for applications where the inlet pressure is unstable or unknown. And our air regulators can be used to adjust the flow rate of gases. We have the perfect solution for your commercial or industrial application. Please browse our website today to find the suitable regulator for your needs.

FAQS
- A pressure regulator is a self-actuated valve that automatically maintains a constant downstream (outlet) pressure regardless of variations in upstream (inlet) pressure or downstream flow demand. It works by using a spring-loaded diaphragm or piston that senses the outlet pressure and adjusts the valve opening to keep it at the setpoint. When downstream pressure drops below the setpoint (due to increased flow demand), the spring pushes the diaphragm open to allow more flow through. When downstream pressure rises above the setpoint, the diaphragm closes against the spring to restrict flow. Pressure regulators are used throughout industrial facilities to reduce high-pressure supply lines to the lower pressures required by individual pieces of equipment — steam pressure reducing stations, compressed air regulation, natural gas distribution, instrument air supply, and process fluid control. Proper regulator selection ensures that downstream equipment receives stable, consistent pressure, which is essential for accurate process control and equipment protection.
- Direct-acting regulators use the downstream pressure acting directly on a diaphragm or piston opposed by a spring to control the valve position. They are simple, reliable, and self-contained — requiring no external power or sensing lines. However, direct-acting regulators exhibit droop (a gradual decrease in outlet pressure as flow increases) because the spring must compress further to open the valve wider, which changes the pressure balance point. They are best suited for applications with moderate flow rates and where tight pressure regulation is not critical. Pilot-operated regulators use a small pilot valve to sense downstream pressure and amplify the control signal to the main valve. This two-stage design provides significantly tighter pressure regulation (less droop), faster response, and higher flow capacity than a direct-acting regulator of the same size. Pilot-operated regulators are the preferred choice for applications requiring precise pressure control, high flow capacity, or wide flow turndown — such as steam pressure reducing stations, gas distribution systems, and critical process control applications.
- Regulator sizing must balance flow capacity, pressure drop, accuracy, and controllability. The regulator must be sized to pass the maximum required flow rate at the specified inlet and outlet pressures — manufacturers publish flow capacity curves or Cv values for each regulator size and model that allow you to verify capacity. Undersizing causes excessive pressure drop, inability to maintain setpoint at high demand, and potential choked flow. Oversizing causes the valve to operate near the closed position, where it becomes sensitive to small disturbances and may produce instability, oscillation, or chattering. The ideal operating range is typically between 20% and 80% of the regulator's maximum capacity. Beyond size, consider the required outlet pressure accuracy (droop, lockup, and creep specifications), the inlet pressure range, the fluid type (air, steam, gas, liquid), and the operating temperature. For applications with wide load swings between minimum and maximum flow, a pilot-operated regulator provides better performance across the full range than a direct-acting type of the same size.
- A backflow preventer is a device that prevents the reverse flow of fluid from a downstream system back into the supply line. It is required whenever there is a risk that contaminated or treated fluid could flow backward into a potable water supply or a clean process line due to back-siphonage (caused by a drop in supply pressure) or backpressure (caused by higher pressure downstream). Backflow preventers are commonly installed in combination with pressure regulators on boiler feed water lines, where the regulator reduces city water pressure to the boiler's required fill pressure. Without a backflow preventer, boiler chemicals and heated water could potentially backflow into the potable water system during a supply pressure drop. Building codes and plumbing standards require backflow prevention wherever a cross-connection exists between a potable water supply and a non-potable system. Combination backflow preventer and pressure regulator assemblies are available as single units that provide both functions in a compact installation.
- Pressure regulator body and trim materials must be compatible with the fluid, temperature, and pressure of the application. Brass and bronze are the standard materials for water, air, and non-corrosive gas applications at moderate temperatures and pressures — they offer good corrosion resistance, are cost-effective, and are widely used in building mechanical systems, boiler feed, and compressed air. Cast iron and ductile iron are used for larger pipe sizes and steam pressure reducing applications where higher pressure ratings are needed. Carbon steel handles high-pressure gas and steam applications. Stainless steel (304 and 316) is specified for corrosive chemicals, food-grade and pharmaceutical applications, sanitary systems, and high-purity gas service. Internal trim components — seats, plugs, and springs — are typically stainless steel regardless of body material. Diaphragm and seal materials include Buna-N for general service, EPDM for steam and hot water, PTFE for chemical resistance, and Viton for high-temperature or aggressive fluid applications. Always verify the regulator's material compatibility with your specific fluid and operating temperature before specifying.
