299H Pressure Reducing Regulator

The 299H Series regulators are pilot-operated pressure reducing regulators with the pilot integrally mounted to the actuator casing.  They are used in natural gas distrtibution systems, gas supply to industrial boilers, furnaces, ovens, mixers, and plant air service.  The Type 299HR has a token internal relief valve to relieve minor overpressure caused by thermal expansion.

This regulator has a pressure control accuracy of + 1% of absolute control pressure, making it an excellent choice for fixed factor billing or pressure factor measurement.
