Gas Regulators
Mountain States is a preferred vendor for A.Y. McDonald regulators.
SR100 Series Residential Regulator
The compact, high capacity A.Y. McDonald SR113 service regulator is designed for residential or light commercial/industrial applications using various hydrocarbon or other non-corrosive gases.
A comprehensive range of springs is available. The outlet pressure can be easily and accurately adjusted by turning the spring adjustment unit located under the top cap. The wide capacity range provides the ability to standardize on varying applications. Full lockup capability provides assurance that downstream pressure will not build up during no-flow situations. Full capacity relief provides safety during abnormal overpressure occurrences.
- Inlet Pressures up to 125 PSIG
- Outlet Pressures: 6″ w.c. to 2 PSIG
1800C Series Residential Regulator
A.Y. McDonald 1800C Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other noncorrosive gases in residential, light commercial, and small industrial applications. The 1800C and C-HC can be installed in both horizontal and vertical pipelines.
A comprehensive range of springs is available. The outlet pressure can be easily and accurately adjusted by turning the spring adjustment unit located under the top cap.
The design of this mechanism provides virtually frictionless adjustment and eliminates “spring wind up”. The complete spring adjustment mechanism can be removed easily for maintenance and spring changes.
- Inlet Pressures up to 125 PSIG
- Outlet Pressures: 3.5” W.C. to 2 PSIG
- All models conform to ANSI Code B109.4-2021, and CGA Service-Type Regulator Specification CAN/CGA-6.18-M22
1800B2 Series Residential Regulator
A.Y. McDonald 1800B2 Series pressure regulators are designed to control natural gas, air, nitrogen, carbon dioxide, propane vapor, and other non-corrosive gases in residential, light commercial, and small industrial applications. The 1800B2 and B2-HC can be installed in both horizontal and vertical pipelines.
A comprehensive range of springs is available. The outlet pressure can be easily and accurately adjusted by turning the spring adjustment unit located under the top cap.
- Inlet Pressures up to 125 PSIG
- Outlet Pressures: 3.5″ W.C. to 2 PSIG
- All models conform to ANSI Code B109.4-2021, and CGA Service-Type Regulator Specification CAN/CGA-6.18-M22
1800CPB2 Series Pilot-Loaded Residential Regulator
The A.Y. McDonald 1800CPB2 regulator is designed for pressure reducing service requiring stability and metering accuracy. They are used on gas distribution systems as intermediate or low-pressure regulators.
They are also effective for large farm and commercial operations with widely varying inlet pressures up to 125 PSIG with accurate control of outlet pressures between 1 PSIG and 30 PSIG. 1800CPB2 regulators are excellent for use with American Meter domestic meters. Model 1883CPB2 is equipped with overpressure shutoff (OPSO) that provides protection against downstream overpressure.
The 1800CPB2 regulator will accurately control the metering pressure to a constant value, thus the pressure correction factor becomes a constant factor for a given metering pressure. The pressure-corrected volume equals meter volume multiplied by the pressure factor constant.
1800/2000 Series Industrial Regulator
A.Y. McDonald 1800 and 2000 Series regulators are suitable for a wide range of large volume usage in commercial, industrial, and gas utility distribution station applications. All units are designed for natural, propane vapor, air, nitrogen, carbon dioxide, and other non-corrosive gases. The 1800 and 2000 Series can be installed in both horizontal and vertical pipelines.
A comprehensive range of springs is available. The outlet pressure can be easily and accurately adjusted by turning the spring adjustment unit located under the top cap. The 1800 Series can be ordered as Full Relief, Partial Relief, or No Relief. 2000 Series Regulators are non-relieving. Both models are available with Over-pressure Shut off, Underpressure Shutoff, and monitor capabilities.
The design of this mechanism provides virtually frictionless adjustment and eliminates “spring wind up”. The complete spring adjustment mechanism can be removed easily for maintenance and spring changes.
- Inlet Pressures up to 125 PSIG
- Outlet Pressures:
- 1800 Series 3.5″ W.C. to 5PSIG
- 2000 Series 0.5 PSIG to 15 PSIG
