Sour Service Capability | Available in configurations that comply with NACE MR0175/ISO 15156 and NACE MR0103. |
Compact Design | The smaller, lighter design of the DF400 control valve makes them easier to handle than standard globe valves of the same size, and usually half the weight. |
Field Service Friendly | No special tools are required to inspect or service trim, and the actuator is field reversible without additional parts. |
Versatile Trim Options | Metal and soft seat trim are available in a wide variety of reduced-port trim options. |
Industrial High Quality External Coatings | Our standard industrial high quality external coatings provide long lasting resistance to the harshest environments. |
Emissions Reducing Packing | Standard low-emission packing prevents the loss of process media and helps reduce packing maintenance. |
Blowout Proof Shaft | DF400 shafts are made with a machined shoulder designed to provide exceptional blowout prevention. |
The Model DF400 (Figure 1) is a heavy-duty eccentric plug control valve (sometimes referred to as a rotary globe valve) combined with a powerful spring-and-diaphragm actuator. This valveactuator combo is used in all kinds of demanding applications, including oil and gas production, chemical process industries and severe service environments.
