Fisher D3 Control Valve

Fisher™ D3 Control Valve

The Fisher D3 control valve is a compact, rugged valve designed for on/off or throttling control, and utilizes FloPro technology, using either pneumatic or electric control.

This valve is ideal for use as a dump valve on gas separators and scrubbers. It is also well suited for other high pressure applications in natural gas production, compression, and processing. NPS 1 and 2 D3 control valves are available with CL900 NPT end connections and CL600 raised face flanged end connections. The D3 offers easy maint

The D3 offers easy maintenance. The trim and packing can be maintained by removing the deep?bore hammer nut and lifting the actuator/bonnet assembly off the valve without disassembling the actuator.

Features Electric and Pneumatic Safer Bonnet / Valve Body Connection--

The unique design provides additional protection if disassembly of bonnet/valve body connection is inadvertently started while there is still pressure in the valve body. Pins mounted in the valve bonnet help ensure the bonnet disengages from the valve body as the hammer nut is loosened, while the threads are still engaged. This allows internal pressure to be vented, while keeping the actuator retained to the valve body. Field?Selectable Flow Rates--The FloPro feature allows adjustment of the flow capacity without changing the trim. In this way, a single trim set can be used for more than one flow requirement, reducing inventory and maintenance costs. See figure 1.
