MR95 Series Pressure Fisher Gas Regulator For Fired Heaters And
Boilers
Fisher MR95 Series Pressure Regulator
Fuel Gas Pressure Control Solutions for Fired Heaters and Boilers
MR95 Series regulators are compact, large-capacity, direct-operated
pressure regulators. Typical applications include superheated
steam, steam injection, steam tracing, nitrogen purging, boiler
feed water, process chemicals, cooling water, test fixtures, wash
tanks, sterilizers/autoclaves, fuel lines, pneumatic supply, and
many others.
