Regulators - Industry Standard for Pressure Regulators and Flow Control Products Emerson Fisher Regulators Documents
Emerson’s Fisher brand regulators offer pressure and flow control products and solutions in three broad categories — industrial gas and liquids, natural gas and propane gas. Fisher’s broad product line offers the most dedicated support of any pressure regulator manufacturer, with the research, engineering, manufacturing and marketing resources in place to serve customers worldwide. Its versatility, stability, in-line maintenance and rugged construction have made Fisher the pressure regulators of choice in thousands of installations around the world.

Fisher MR95
Pressure Reducing
Fisher pressure reducing regulators maintain desired outlet pressure providing the required flow to satisfy a variable downstream demand. The level at which the reduced pressure is maintained is the outlet pressure setting of the regulator.

Fisher MR98
Relief / Backpressure
Fisher backpressure regulators maintain desired upstream pressure by varying the flow in response to changes in upstream pressure. Pressure relief valves provide overpressure protection in case of unexpected pressure buildup.

Fisher VS100
Shutoff Devices
Fisher pressure shutoff or slam-shut devices shut off the gas flow when the sensed control pressure passes a set limit in response to a low-pressure condition, a high-pressure condition, or both.



Skids are prefabricated pressure-reducing stations designed to the customer’s specifications, then built to order and include a range of products from our brands, Fisher, Francel and Tartarini, such as regulators, manual isolation valves, and piping.

Freeze-Fiter Plus+Freez-Fiter Plus + America's Favorite Pilot Heater - Providing Higher Accuracy, Updated Features & Customization to Your Needs!
• The Freez-Fiter Plus pilot heater has been re-engineered for greater airflow efficiency, and more uniform temperature control.
• New 6" enclosure has the same convenient O.D. (12" X 12") and uses the same R8 2500 BTU heater, but the case is now 6" deep for significantly
greater airflow performance.
• Single or double coil serpentines are 3/8" stainless steel, and have 2500 lbs. of maximum working pressure. They are tested to 5000 lbs.
• Bulk heads have been re-engineered, and all high pressure connections are external: there are no high-pressure connections inside the enclosure.
• The low pressure regulator is a standard 912, (BelGas or Fisher). These direct-operated, spring-loaded regulators have limited-capacity external relief across the diaphragm to minimize over-pressure. Using natural gas, they have a 50 psi maximum inlet. The outlet is 3.5" w.c. to operate the Freez-Fiter.
• The Mertek thermostatic gas valve replaces the older thermostat and Baso valve. Both the gas valve and safety valve are CSA and FM approved.
• For greatest safety and convenience, a shutoff valve turns the gas off on the fuel inlet entering the heater.
• All pilot heater units have a preheat fuel tube, which prevents high pressure regulator freeze-up.
• A filter on the low side of the fuel inlet slows the moisture and debris and prevents it from entering the heater. This filter also extends the service life of the pad.
• Freez-Fiter Plus units have a 0-15" w.c. gauge, easily visible from the front.
• Freez-Fiter pilot heater units have a new rain-bill feature that protects the unit from rainwater.
• Every unit is leak-tested and pressure-checked in the Bruest lab.
• Heater is Class 1, Division 1 and 2, Group D approved. (CSA and FM)
• Freez-Fiter works well in a high pressure or low pressure setting, AND costs less than competitive devices that only work well on high pressure gas.

Freese-Fiter Plus+
Freez Fiter is also easier to install, requiring less pipe, fittings and regulators. Options for the Freez-Fiter Plus pilot heater include a 12 volt or 120 volt design and several types of high pressure regulators. A larger unit, 16"X16", with an R12 5000 BTU heater is also available. Freez-Fiter Plus is a field-proven pilot heater backed by Bruest, the nation's most respected provider of heating systems for gas transmission and distribution lines, and utilities.
