Fisher 133 series direct operated regulators are idea 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 effeciency despite varying inlet pressures.

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. Type 299HV with Type VSX8 are used in applications where the gas supply must be shutoff. The 299HR integral token relief alerts you to an increase in downstream pressure beyond the regulator set point. Type 299HVR token internal relief valves to relieve minor thermal expansion overpressure.

Fisher type 1098-EGR and 1098H-EGR regulators provide economical and accurate pressure control in a wide variety of applications, natural gas distribution systems, fuel gas supply to industrial boilers, furnaces ovens and mixtures and large commercial/industrial establishments such as shopping centers and schools. They are also used in plant air service and liquid service

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. 289 Series relief valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. 289 Series relief valves are designed for pressure control; they are not ASME safety relief valves.

The 67C Series regulators are typically used to provide constantly controlled, reduced pressures to pneumatic and electro-pneumatic controllers and other instruments. These direct-operated regulators are suitable for most air or gas applications. Other applications include providing reduced pressures to air chucks, air jets and spray guns.
