Regulator Types
RegO First Stage Regulators
First Stage Regulators, High Pressure Domestic
Provides accurate first stage regulation in two-stage bulk tank systems. Reduces tank pressure to an intermediate pressure of 5 to 10 PSIG. Also used to supply high pressure burners for applications like industrial furnaces or boilers. Domestic LP-gas installations, also incorporated in multiple cylinder installations.
RegO Low Pressure Second Stage Regulators
Second Stage Regulators Low Pressure, Domestic
Designed to reduce first stage pressure of 5 to 20 PSIG down to burner pressure, normally 11” WC. Ideal for medium commercial installations, multiple cylinder installations and normal domestic loads.
Backmount Design
Mounts directly to house line piping. Eliminates need for union joints and elbows and mounting brackets. Quick and easy to install.
RegO Low Pressure Second Stage Tobacco Barn Regulator
Especially developed for drying barns in the tobacco industry. The LV5503G4 regulator will supply a steady and constant flow of fuel to as many as 12 to 20 burners throughout the barn.
RegO Compact Twin Stage Regulators
This compact two-stage regulator is designed to reduce container pressure down to 11” WC delivery pressure. It is ideal for “on-site” cylinder applications, such as homes, mobile homes and average domestic service including small ASME and 100 to 420 pound DOT cylinders.
RegO Twin Stage Automatic Changeover Regulators
Application:
These combination automatic changeover, two stage regulators are especially suitable for homes, mobile homes, cottages, construction and other portable two cylinder installations. Empty containers may be replaced without interrupting customer’s gas service.
Features:
- Automatic changeor switches from “service” to “reserve” cylinder automatically without interrupting service.
- The Second Stage Incorporates wide bonnet drip lip vent to guard against freeze-up when properly installed.
- With 15 PSIG inlet pressure, the second stage regulator is designed to not pass more than 2 PSIG with the seat disc removed.
- Allows "reserve" cylinder to supplement the flow of gas from the "service" cylinder during extreme load or severe cold conditions.
- Incorporates molded diaphragm in second stage regulators.
- Integral indicator gauge.
- Change over knob and indicator are integral to the first stage.
- Select brown finish on first stage.
RegO Single Stage Compact Regulators
These compact regulators are designed for smaller outdoor grills and fish cookers. They are intended for use on small portable appliances that use 100,000 BTUs/hr. or less. They may not be used on fixed pipe systems per NFPA 58, 1995 edition.
RegO Second Stage Regulator For 2 PSIG Systems
Designed to reduce first stage pressure of 10 PSIG down to 2 PSIG. A line pressure regulator is required downstream to reduce the 2 PSIG to a nominal 11” WC.

Fairview Automatic Changeover Regulators
Low Pressure Two-Stage Automatic Changeover
Automatically redirects LP gas vapor flow from an empty designated service cylinder to a reserve cylinder without interruption of service. It features a green indicator dome which changes to red when the service cylinder needs to be refilled.
SPECIFICATIONS:
- Zinc Die Cast
- Molded Rubber Diaphragms
- UL Listed
- 2nd Stage Relief Mechanism Per U.L. 144
- Powder Coated
Fairview Single Stage Regulators
Low Pressure Single-Stage Regulators
The model GR-800 regulator incorporates a drip lip vent and is ideally suited for use with portable devices.
SPECIFICATIONS:
- Zinc Die Cast
- Molded Rubber Diaphragm
- Underwriters Laboratories Listed
- Integral Pressure Relief
Maxitrol Regulators
Maxitrol 325 Series Regulators
325 Series pounds to inches regulators are for use on residential, commercial, and industrial applications. The 325 Series features a high leverage valve linkage assembly to deliver positive dead-end lock-up. The regulators are capable of precise regulating control from full flow down to pilot flow.
B Models:
Imblue Technology increases corrosion resistance and provides extra protection against the elements for regulators used in outdoor applications.
Maxitrol Regulators with OPD
The 325 Series with OPDs features a high leverage valve linkage assembly to deliver positive dead-end lock-up. The regulators are capable of precise regulating control from full flow down to pilot flow.
High Pressure Industrial/Commercial Pounds-to-Pounds Regulators
Designed to reduce propane gas container pressure down to between 3 and 100 PSIG. Ideal for liquid or vapor service, they can be used in a variety of applications, including salamander heaters, weed burning toches, fish cookers, tar pot heaters and other industrial type services.
FEATURES:
- Provides high capacity performance at a reasonable price
- Suitable for both liquid and vapor service.
- Compact design provides easy installation
- Consistent delivery pressure, especially in cold weather, helps assure maximum performance from the second stage regulator
High Pressure Industrial / Commercial Regulators
Designed to reduce container pressure to between 3 and 125 PSIG. Precision-built with a multi-million BTU capacity. Ideal as a first stage regulator in large, multiple container operations. Also ideal for crop dryers, asphalt plants and “tar wagons.” Large nozzle and straight through flow provides capacity and resistance to freeze up. Suitable for both liquid and vapor service. Can be readily fitted with pressure gauge or 3139 series relief in 1/4” F.NPT port.
High Pressure/High Temperature Industrial/Commercial Pounds-to-Pounds Regulators
Application:
Designed to reduce LP-gas container pressures to between 3 and 50 PSIG. Ideal for crop drying, heat treating, asphalt batch mixing and other large industrial and commercial load application utilizing high temperature LP gas or high temperature atmosphere under conditions up to 300°F. Also ideal as a first stage regulator in large multiple operations.
FEATURES:
- Special diaphragm and seat materials are suitable for up to 300°F. temperatures.
- Large nozzle and straight through flow provides high capacity and resistance to freeze ups.
- Suitable for both liquid and vapor service.
- Can be fitted with high pressure gauge in 1.4" F. NPT port. Engineered Controls International, Inc. recommends that these gauges use silver braze rather than soft solder construction.
Belgas Low Pressure Second Stage Regulators
Intermediate Commercial
The B34 service regulator is a versatile, large diaphragm-controlled regulator designed for commercial and industrial loads. The B34 maintains accurate regulation on applications where frequent sudden load changes can occur.
The B38 service regulator is designed for use on large commercial and industrial loads. Large orifices are available (up to 1 3/8") for high capacity/low inlet pressure applications. An added feature of the B38R is its massive relief capacity.
Light Commercial
The B42 service regulator incorporates a molded diaphragm and increased lever ratio into a conventionally designed regulator. The result is a lighter, more compact unit that provides the power, capacity, and relief performance of much larger regulators.
