Fisher™ Types 1098-EGR and 1098H-EGR Pressure Reducing Regulators
The Fisher 1098-EGR and 1098H-EGR regulators provide economical and accurate pressure control in a wide variety of applications. They are also used in plant air service and in liquid service where a slow stroking time (approximately 30 to 90 seconds) is desired on both opening and closing the main valve.
The superior performance of this regulator is due to the amplifying effect of the pilot and the two-path control system. Changes in outlet pressure act quickly on the actuator diaphragm to provide fast response to system changes. Then, the pilot amplifies any small system changes to position the main valve for precise pressure control.
