Fisher® D4

Fisher® D4 control valve is a compact, rugged globe valve designed primarily for high-pressure throttling applications. 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 build up on internal valve parts. The trim and packing can be maintained by removing the patented deep-bore hammer nut and lifting the actuator/bonnet assembly off the valve without disassembling the actuator. The unique D4 design provides additional protection if disassembly of bonnet/valve body connection is 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.
