Dyna-Flo, a business unit of Curtiss-Wright, has over 30 years of expertise in providing high-performance control valve systems for industries such as oil & gas, chemical processing, power generation, and more. Their product offerings include a variety of control valves, actuators, and integrated valve systems designed for safe, reliable, and efficient operation. Notable products include the DF400 Rotary Plug Valve and the 320 AxFlo Anti-Cavitation Valve, both designed to enhance performance in demanding applications. Dyna-Flo’s commitment to innovation, reliability, and customer support helps businesses reduce operational costs while maximizing safety and efficiency in their processes.

360 Series General Purpose Control Valve

360 Series control valves are heavy-duty globe and angle style valves perfect for general service or severe service applications. These valves are used in a variety of demanding environments, including oil and gas, chemical/ petro-chemical, power generation, water distribution and/or treatment, and general industries.

The standard actuator for 360 Series valves is a Dyna-Flo Model DFC (fail closed) or DFO (fail open) linear actuator. These heavy-duty actuators are spring and diaphragm style, and can be used for throttling or on-off service, with or without a valve positioner.

DF400 Series Rotary Plug Control Valve

The Model DF400 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 valve-actuator combo is used in all kinds of demanding applications, including oil and gas production, chemical process industries and severe service environments.

The self-aligning eccentric plug design and straight through flow pattern of the DF400 control valve provides tight shutoff while also allowing for higher flow capacities than other valves. The exclusive low-profile actuator provides reduced deadband and hysteresis through a combination of low-friction design with a robust splined shaft connection.

320 Series Axflo Anti-Cavitation

320 AxFlo Anti-Cavitation trim is a heavy duty dirty service trim option designed for entrained particulate and high pressure drop applications. AxFlo trim offers multi-stage protection against cavitation and erosion.

You can expect enhanced trim life when using AxFlo trim because pressure gets distributed over the length of the valve plug across multiple STAGES. Each STAGE is not exposed to the full pressure differential, and on properly sized 320 valves, the amount of pressure drop per STAGE is controlled to prevent cavitation.
