Product Description

Fisher 299H Series pilot operated pressure reducing regulators provide controlled pressure and capacities for distribution, industrial and commercial applications with inlet pressures up to 175 psi/12.1 bar. Type 299HV with Type VSX8 are used in applications where the gas supply must be shutoff. The 299HR integral token relief alerts you to an increase in downstream pressure beyond the regulator set point. Type 299HVR token internal relief valves to relieve minor thermal expansion overpressure.
