Fisherr D4 Control Valve Assembly

The Fisher D4 control valve is a compact, rugged globe

valve designed primarily for high-pressure throttling

applications using either pneumatic or electric control.

This valve is ideal for use on pressure and flow control

applications within the oil and gas production industry.

The D4 is an excellent control valve for high-pressure

separators, scrubbers, and other processing

equipment. These valves are especially useful for

either throttling or on/off control of liquids or gases

which are gritty, sticky, or which have a tendency to

builduponinternalvalveparts.

If the control valve requires 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– 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 removed, while the threads are still

engaged.

 Heavy-Duty Guiding–Massive guiding (figures 1 and

2) positively aligns the valve plug in the seat ring for

reliable service. The screwed-in seat ring completely

encloses the seat ring gasket.

 Live-loaded Packing System–The packing system

provides an improved stem seal to help prevent the

loss of valuable or hazardous process fluids or gases.

It features Fisher ENVIRO-SEALt packing

technology to provide reduced packing

maintenance.
