Fisher Type 99 gas regulator provides a broad capacity for controlled
pressure ranges and capacities in a wide variety of distribution,
industrial, and commercial applications.
Type 99 regulator has a Type 61L (low pressure), Type 61H (high
pressure), or a Type 61HP (extra high pressure) pilot integrally mounted
to the actuator casing. Type 99 regulator can handle up to 1000 psig /
69.0 bar inlet pressures (the 1000 psig / 69.0 bar regulator requires a
Type 1301F pilot supply regulator and a Type H110 pop relief valve).
pilot supply regulator reduces inlet pressure to a usable 200 psig /
13.8 bar for the extra high pressure pilot. 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.
