Fisher™ Type EZR Relief Valve or Backpressure Regulator

The automatic spring-loaded relief valves are designed to keep line pressure below preset values. They are mounted downstream of regulators and perform the specific function of releasing small amounts of gas in the event of the regulator not closing properly. V Series is in conformity with the Pressure Equipment Directive PED 97/23/EC and is classified in Max. Category I

MR98 Series is used for backpressure or relief applications in liquid, gas, air, and steam service. The Types MR98L, MR98H, and MR98HH are direct-operated and spring-loaded. The Types MR98LD, MR98HD, and MR98HHD use additional pressure loading to maintain relief differential pressures, backpressures or for remote setpoint adjustment.

Type ACE95 vapor saver is a pilot-operated valve used for accurate pressure control on low pressure blanketing systems. The unit is stainless steel actuated by a very large rolling diaphragm actuator and can accurately control the blanketing pressure by a single adjusting screw.

1805 Series relief valves are designed for use in farm tap applications where a relief valve is needed between the first-stage and second-stage regulators.1805 Series relief valves are suitable for natural gas,air, propane, or any medium compatible with the internal valve parts.Relief pressures range from 5 to 125 psig / 0,34 to 8,6 bar. Maximum pressure, including buildup, is 150 psig / 10,3 bar
