B Series

The B Series Pressure Regulating Valves are used for reducing pressure in air and water systems. These regulators are commonly found in industrial plants, apartment buildings, water supply systems, schools and underground water distribution systems.CATALOG SPEC SHEET(S) Model: B Series
Service: Water, Air, Oil, Other Gases & Liquids
Body Material: Bronze (1 1/2" - 2 1/2"), Cast Iron (3" & 4")
Max Capacity (4" Size, Water): 912 GPM
Max Inlet Pressure: 250 PSIG
Max Diff. Pressure: 125 PSIG
Sizes: 1/2" - 4"
Connections: NPT, 125# FLG, 250# FLG
     

455 Series

The 455 Series are Balanced, Externally-Sensed Pressure Regulating Valves that are used for reducing pressure in steam, air and water systems. Commonly used in heating and other process applications. Externally-sensed regulators are often more accurate than internally-sensed regulators because the sensing line is connected close to the process it is intending to control and is far enough away from the outlet of the regulator to not be affected by turbulence.CATALOG SPEC SHEET(S) Model: 455 Series
Service: Steam, Air, Water & Other Gases
Body Material: Bronze ( 1/2" - 1 1/2"), Cast Iron (2" - 4")
Max Capacity (4" Size, Steam): 33,040 lbs/hr
Max Inlet Pressure: 250 PSIG
Max Diff. Pressure: 125 PSIG
Sizes: 1/2" - 4"
Connections: NPT, 125# FLG, 250# FLG
     

403 Series

The 403 Series Internally Pilot-Operated Pressure Regulating Valves are used for pressure reduction on steam mains and other process equipment. Pilot-operated regulators will maintain a constant and accurate downstream pressure regardless of fluctuations in supply pressure or usage. These regulators can be supplied with an internal sensing option eliminating the external sensing line.CATALOG SPEC SHEET(S) Model: 403 Series
Service: Steam & Air
Body Material: Ductile Iron
Max Capacity (4" Size, Steam): 83,300 lbs/hr
Max Inlet Pressure: 450 PSIG
Max Diff. Pressure: 250 PSIG
Sizes: 1/2" - 4"
Connections: NPT, 150# FLG, 300# FLG
