Product Bulletin Fisher™ 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 build up on internal valve parts. 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. W9933-5 FISHER D4 CONTROL VALVE WITH Gen 2 easy-Drive™ ELECTRIC ACTUATOR (NPS 2 RF FLANGED END CONNECTION) Features Electric and Pneumatic n 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. n Heavy-Duty Guiding—Massive guiding (figures 3 and 4) positively aligns the valve plug in the seat ring for reliable service. The screwed-in seat ring completely encloses the seat ring gasket. n Quad-O compliant Packing System --Features Fisher ENVIRO-SEAL™ packing technology to provide reduced packing maintenance and meet Low E fugitive emission requirements for Leak Detection and Repair (LDAR) programs in compliance with the Code of Federal Regulations (CFR) 40, Part 60, Subpart OOOO. FISHER D4 CONTROL VALVE (NPS 2 NPT END CONNECTION) n NACE Constructions—NACE compatible trim is available with the D4 control valve. These constructions meet the metallurgical requirements of NACE MR
