Fisher Natural Gas – Fuel Gas Regulators

Fuel Gas Regulators


66 Series Pressure Reducing Regulators




The Type 66 self-operated regulator maintains a reduced outlet pressure while satisfying the downstream flow demands.  The Type 66Z and 66ZZ self-operated regulators also control a reduced outlet pressure; however, both have springs sensitive to negative pressures and can be used for vacuum regulation.  Each regulator type has a balancing diaphragm which increases accurate and sensitive response to pressure changes by reducing the unbalanced forces acting on the valve plug.

Type 99 Pressure Reducing Regulator

The Type 99 regulator typically provides fuel gas to boilers, furnaces, ovens, mixers, and large commercial or institutional installations.

The key to the operation of a Type 99 regulator is the yoked double-diaphragm pilot. Fast response and accuracy are made possible by the amplifying effect of the pressure-balanced pilot and by the two-path control system. The function of the pilot is to sense change in the controlled pressure and amplify it into a larger change in the loading pressure . Any changes in outlet pressure act quickly on both the actuator diaphragm and the loading pilot, thus providing the precise pressure control that is characteristic of a two-path system.

299HS Series Pressure Reducing Regulators with Slam-Shut Device

The 299HS Series with Type VSX-2 is used in applications where the gas supply must be shut off in the event of an accidental rise or drop in downstream pressure beyond a predetermined setpoint.  Pilot supply pressure also shuts off.  The Type 299HSR has a token internal relief valve to relieve minor overpressure caused by thermal expansion. 

The Type VSX-2 module on a 299HS Series is a fast-acting shutoff valve that provides over or underpressure protection by completely shutting off the flow of gas to the downstream system.  The shutoff module's actions are independent of the Type 299HS regulator and of variations in the inlet pressure.

S200 Series Pressure Reducing Regulators

The quick-reacting S200 Series pressure reducing service regulator is typically used in an industrial or commercial installation to minimize the shock effect of sudden downstream load changes that might otherwise activate safety shutoff equipment. In such an installation, where gas consumption varies from almost nothing to several thousand standard cubic feet per hour (scfh) (or normal cubic meters per hour (m3/h(n)), snap-acting solenoid valves can cause sudden load changes. The resulting shock pressures and regulator instability can cause safety equipment to shut the installation down. But with an S200 Series regulator, transmission of shock loads to downstream equipment is reduced, thereby helping maintain downstream pressures within desired limits.

The S200 Series regulators are available in several different configurations to meet the demands of varying services and overpressure protection requirements. Each configuration is made up of different construction features. The following section describes the available construction features.
