Fisher 133 Series direct-operated regulators are ideal for industrial and commercial applications supplying gas to furnaces, burners, and other appliances. A balancing system enables the regulator to control gas pressure accurately for maximum combustion efficiency despite varying inlet pressures.
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
Fisher 289 Series relief valves are spring-loaded throttling relief valves used as downstream pressure regulators to protect the system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation.
Fisher 299H Series pilot operated pressure reducing regulators provide controlled pressure and capacities for distribution, industrial and commercial applications with inlet pressures up to 175 psi/12.1 bar. 299HS with Type VSX2 and 299HV with Type VSX8 are used in applications where the gas supply must be shutoff.
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).
Fisher 627 Series direct-operated pressure reducing regulators are for low and high-pressure systems. These regulators can be used with natural gas, air or a variety of other gases. Performance characteristics vary according to construction.
