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

402 Series
 |
The 402 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) |
