Fisher Type 1301F / 1301G High-Pressure Regulators
Manufacturer / Brand: Emerson (Fisher)
Type: Self-operated High-Pressure Reducing Regulator
Description
The Fisher Type 1301F and 1301G regulators are direct-operated, high-pressure reducing regulators designed to reduce and regulate high pressure gas (or other fluids) in applications where a downstream lower pressure supply is needed. They are often used to supply pilot pressure for pilot-operated regulators or as loading (control) pressure sources in pressure-loaded regulator systems. They may also be used in general high-pressure reduction service for gases, liquids, or water in industrial installations.
The rugged and versatile design supports high inlet pressures (up to 6000 psig / 414 bar), with different outlet pressure ranges depending on variant. The regulators are available in multiple body materials, spring ranges, and connection styles, suitable for harsh service, and may be built to comply with NACE requirements or hydrogen-ready specifications.
