Fisher Types 1301F and 1301G regulators are self-operated, high-pressure regulators, can be used where high pressure gas must be reduced for use as pilot supply pressure in pilot-operated regulator or as loading pressure in pressure-loaded regulators.

Fisher 1305 Series regulators are direct-operated, pressure reducing regulators that resist hydrate formation and regulator freeze-up.

Fisher Type 1367 high-pressure instrument supply system takes a pressure of up to 2000 psig / 138 bar and reduces it to a controlled pressure to be used for supplying a pneumatic instrument.

Fisher 167D Series switching valves are typically used to deliver constant reduced pressure of gaseous fluids to pilot-operated controllers and other pneumatic instrumentation.

Fisher 67C Series direct-operated regulators and filter regulators provide constantly controlled, reduced pressures to pneumatic and electropneumatic controllers and other instruments.

Fisher 67D Series pressure reducing regulators and filter regulators deliver constant reduced pressure of gaseous fluids to pilot-operated controllers and other pneumatic instruments.
