The 99 Series commercial/industrial regulator is a pilot-operated unit that keeps outlet pressure constant despite varying flow rates and inlet pressures. It can be used for either low or high-pressure applications while maintaining accuracy.

Ease of maintenance is only one of the many features of the 99 Series. No upstream pilot supply line on standard installations reduces cost. The actuator diaphragm and pilot respond simultaneously to control final positioning of the main valve, permitting full main valve travel and higher capacity capabilities.

Other spring ranges are available on the 99 Series. See your Fisher Distributor for details.

The 133 Series direct-operated regulators are ideal for industrial and commercial applications supplying gas to furnaces, burners, and other appliances. A balancing system enables the regulator to control gas pressure accurately for maximum combustion efficiency despite varying inlet pressures.

The 299 Series is a high capacity, pressure control regulator which uses a pilot to keep outlet pressure constant despite varying flow rates and inlet pressures. This lightweight yet dependable regulator is used for applications from large commercial sites to smaller multi-dwelling establishments.

This is not an adaptation of existing regulator design; it is an all new design of integrated cases and internal registration ports. The 299 Series is available with optional external registration for extremely accurate outlet control, a 2-inch flanged body, and cast iron or steel body material.

The 627 Series commercial/industrial regulator is a large capacity, high-pressure unit for use in conjunction with S302G or S202G Series regulators. It can also be used on Final-Stage service. A 1805 Series relief valve is recommended to prevent excessive build-up in the downstream line.

The diaphragm case and/or regulator body on the 627 Series can be rotated in any of four positions to allow installation in locations with limited space.

The 630 Series Commercial/Industrial regulators are large capacity, high-pressure units for use in conjunction with S302G or S202G Series regulators. They can also be used on Final-Stage service.

A 1805 Series relief valve is recommended to prevent excessive build-up in the downstream line.

The S102CL Series regulators are used in factories, office buildings, restaurants, and other commercial and industrial installations. These regulators feature improved overpressure protection.

At 6 pounds (2,7 kg), the S102CL Series is both lightweight and compact for installations where space is limited. The vent can be located in any one of four positions to accomodate tight installations. Normally used in low-pressure applications, this unit is versatile, and can be adapted to fit your needs.

The S202G Series Commercial/Industrial regulators are large capacity, low-pressure units for installation at schools, bakeries, and similar installations. They contain a limited capacity internal relief valve and can be used in conjunction with either the 627 Series or 630 Series high-pressure regulators.

For high capacity installations, a 289 or 289P Series relief valve is required in the downstream system. For additional spring ranges and orifice sizes, contact your Fisher Distributor.

The S302G Series Commercial/Industrial Regulators are large capacity low-pressure units for installation at schools, bakeries, and other similar installations. They contain a limited capacity internal relief valve and can be used in conjunction with either Type 627 or Type 630 high-pressure regulators.

For high capacity installations, a Type 289 relief valve is required in the downstream system. For additional spring ranges and orifice sizes, contact your Fisher Distributor.
