    Fisher 167DA Series Switching Valve Three-way Pressure Reducing Regulator Valve

    Fisher 167DA Series Switching Valve is a three-way valve typically used to deliver constant reduced pressure of gaseous fluids to pilot operated controllers and other pneumatic instrumentation.

    The Types 167D and 167DS are two-way switching valves.

    The Types 167DA and 167DAS are three-way switching valves.
    Features:

    Compact—The Types 167D and 167DA switching valves are engineered for outstanding performance in a compact, light weight package.

    Easy, Accurate Adjustment—With a choice of springs for optimum resolution, the switching point is set to a specifi c requirement by an adjusting screw atop the spring case.

    Sour Gas Service Capability—NACE MR0175 and MR0103 compliant construction available.

    Optional Stainless Steel Construction— The Types 167DS and 167DAS provide high resistance to corrosion especially benefi cial for offshore applications.

    Ease of Maintenance—No special tools are required to perform maintenance, and all maintenance can be performed with the valve in the line.

    Rugged Construction—The Types 167D and 167DA switching valves are engineered for longer service life with minimal maintenance requirements.

    Corrosion Resistant Fasteners—Bolting and adjusting screw are double zinc-chromated for enhanced corrosion resistance. Optional stainless steel bolting and adjusting screw are also available.

    Installation

    The switching valve can be mounted in any position, providing the vent in the spring case is free from obstruction. Connect the pneumatic control line to the port marked “D” on the valve body. Ports A and C (and B on the Types 167DA and 167DAS valve) are connected for the desired switching valve response to loss or decrease in pneumatic pressure. Figure 5 shows typical application of the Types 167DA and 167DAS switching valve. If the control valve inlet pressure falls below a predetermined setting, the on-off controller turns off control pressure to the switching valve. This causes the switching valve to bleed the control valve diaphragm pressure to atmosphere, closing the control valve. The control valve remains closed until the inlet pressure is restored to the desired setting.
