Product Overview



Fisher brand Type 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. The actuator diaphragm and pilot respond simultaneously to control final positioning of the main valve, permitting full main valve travel and higher capacity capabilities.
