Fisher 61 Series pilots are used with Types 1098-EGR and EZL regulators, and their counterparts are used with 99 Series regulators and are available in a variety of styles – low pressure (L), low pressure and wide proportional band (LE), low pressure and narrow proportional band (LD), high pressure (H), and extra-high pressure (HP).
Pilot-operated regulators use inlet pressure as the operating medium, which is reduced through pilot operation to load the actuator diaphragm.
