Fisher regulators are built to accommodate a variety of industrial needs including compensation for variation in tank pressure, component manufacturing and testing , analytical instrumentation, environmental compliance, and electronic manufacturing. Fisher regulators offer flexibility in body sizes and end connections, outlet pressure settings, orifice sizes, as well as the option for internal or external pressure registration.


Fisher regulators are built to handle your toughest oil and gas production applications. Offered in a variety of materials, NACE certified. We also offer a wide material selection, such as steel, stainless steel, Monel, Hastelloy C, ethylenepropylene (EPDM), fluoroelastomers (FKM), perfluoroelastomers (FFKM), and Teflon (TFE and PTFE), for applications requiring special constructions.


Fisher pressure reducing regulators reduce gas pressure to a distribution level for companies in larger towns and cities to supply gas. Typical applications can reduce pressure from 300psig or more to 60psig or less.

Direct Operated Regulators
Pilot Operated Regulators


Fisher pressure reducing regulators supply natural gas through transmission pipelines across long distances using control valves, pilot-operated regulators, and relief valves to control the pressure and flow of gas. EZH (Spring-to-Close) and EZHSO (Spring-to-Open) Series regulators are accurate pilot-operated, pressure balanced, soft-seated regulators. They are designed for use in high pressure natural gas transmission/city gate stations, large capacity distribution systems, and power plant feeds. They provide smooth, reliable operation, tight shutoff and long life.


Fisher pressure reducing regulators deliver very high levels of accuracy and flexibility demanded by the latest applications in the pharmaceutical industry. These self-operating regulators provide the ability to handle large capacities in a compact design.


Sanitary valves are designed to meet the stringent demands of today’s state-of-the-art Life Science facilities. Polished, stainless steel body and trim components ensure efficient cleaning and sanitizing giving you confidence that your processing environment produces the highest purity.
