Fisher Type EZR pilot-operated, pressure relief valve or backpressure regulator is typically used in city gate and district stations as a relief valve for overpressure protection, or in commercial and industrial applications as a backpressure regulator. It provides smooth, quiet operation, tight shutoff, and long life, even in dirty service.

Type 630R is a general relief valve available in NPS 1 & 2 / DN 25 & 50 body sizes for compressor stations, refineries and similar plants requiring backpressure gas regulation settings up to 250psi/7,2bar. Available in high & low pressure constructions. Low pressure units have larger diaphragm areas to provide accurate control in low pressure settings.

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

Type 1805P-6358 relief valve is an accurate, low-cost, pilot-operated relief valve consisting of a Type 1805P main valve and a Type 6358 pilot. It is available in the NPS 2 size and is capable of relief pressure settings of 10 to 100 psig / 0,69 to 6,9 bar in three ranges.
