Fisher 61 Series Pilots are used with the Type 1098-EGR and EZL regulators and their counterparts are used with 99 Series regulators. 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 Constructions: Type 61L: Low-Press Pilot Type 61LD: Low-Press Pilot w/Narrowing Proportional Band Type 61LE: Low-Press Pilot w/Broadened Proportional Band Type 61H: High-Press Pilot Type 61HP: Extra High-Press Pilot
