1 D4 Control Valve AssemblyThe Fisher D4 Control Valve is a compact, rugged globevalve designed primarily for high-pressure throttlingapplications using either pneumatic or electric Valve is ideal for use on pressure and flow controlapplications within the oil and gas production D4 is an excellent Control Valve for high-pressureseparators, scrubbers, and other processingequipment. These valves are especially useful foreither throttling or on/off Control of liquids or gaseswhich are gritty, sticky, or which have a tendency tobuild up on internal Valve the Control Valve requires maintenance.

2 The trim andpacking can be maintained by removing the deep-borehammer nut and lifting the actuator/bonnet assemblyoff the Valve without disassembling the and Pneumaticn Safer Bonnet / Valve Body Connection Uniquedesign provides additional protection if disassemblyof bonnet/ Valve body connection is inadvertentlystarted while there is still pressure in the Valve mounted in the Valve bonnet help ensure thebonnet disengages from the Valve body as thehammer nut is removed, while the threads are Heavy-Duty Guiding Massive guiding (figures 1 and2) positively aligns the Valve plug in the seat ring forreliable service.

3 The screwed-in seat ring completelyencloses the seat ring Quad-O compliant Packing System --Features FisherENVIRO-SEAL packing technology to providereduced packing maintenance and meet Low Efugitive emission requirements for Leak Detectionand Repair (LDAR) programs in compliance with theCode of Federal Regulations (CFR) 40, Part 60,Subpart D4 Control Valve WITH Gen 2 easy-Drive ELECTRIC ACTUATOR (NPS 2 RF FLANGED END CONNECTION) Fisher D4 Control Valve (NPS 2 NPT END CONNECTION)W9933W8531n NACE Constructions NACE compatible trim isavailable with the D4 Control Valve .

This trim is designedspecifically for severe service applications in the oiland gas industry. Durable tungsten carbide trimmay benefit your application by wearing better andlasting Easy Installation Compact design allowsinstallation where space is a premium.

5 Screwedvalve bodies feature compact face-to-facedimensions while flanged Valve bodies conform toISA-75 standards for maximum Easy Maintenance Hammer nut bonnet/body jointallows repair or maintenance with a minimum oftools, without removing the Valve body from thepiping system. Seat ring can be removed with astandard Integral Bonnet Flange Bonnet has an integralflange that accepts hammer nut force when makingthe bonnet-to-body connection. There are no snaprings subject to possible failure in sour service or inatmospheric Standard Trim for Throttling or On-Off Service Micro-Form trim is standard for throttling or on-offservice at no extra Application Flexibility Choices of port diameters upto mm ( inches)

6 , end connections, andtrim materials suit these valves to manyapplications, including sour Low Power Consumption-- The Fisher easy-Driveelectric actuator operates with 9 to 30 VDC and lessthan watt hours per operation, using Modbus,4-20 mA, or dry contact Control Low Temperature-- The easy-Drive electric actuatordesign allows use in ambient temperatures as lowas -20 C (-4 F) without use of a Easy Installation--The compact design allowsinstallation where space is a premium. Fishereasy-Drive calibrates by simply opening and closingthe Remote Monitoring and Configuration-- Loss ofsignal position is programmable over Low Temperature Materials-- Valve constructionmaterials allow use in applications as low as -40 C(-40 F) for the pneumatic Control valves may be installed in any position, butnormally the actuator is vertical and above the the Control Valve so the flow direction arrow onthe side of the Valve body indicates the direction of theprocess are shown in tables 12 and 13 and figures 1 and ValveD103039X012 Product .
