Fisher Type 99 gas regulator provides controlled pressure ranges and capacities for distribution, industrial, and commercial applications. Type 99 regulator has a Type 61 pilot integrally mounted to the actuator casing. Type 99 regulator can handle up to 1000 psig / 69.0 bar inlet pressures. This regulator comes standard with O-ring seals on the guide bushing and valve carrier to keep main valve body outlet pressure from interfering with outlet pressure in the lower casing assembly.
