For control valves, the operating medium is still mainly pneumatic, but the positioning intelligence has moved to a digital interface. This means that with enhanced control, there also is an opportunity to gather a significant amount of diagnostic data on the control valve assembly itself.

Directional control valves are designed to control direction of flow, while actuators maintain required speeds and precise positions. Magnetorheological (MR) fluid is a controllable fluid. Utilizing the MR fluid properties, direct interface between magnetic fields and fluid power is possible, withou

Control valves are typically applied in continuously throttling services to maintain a specific set point or operating range for different process variables, such as pressure, temperature and flow rate.

The control valve was adequately controlling the process, but the actuator required more thrust than typical to move the valve back and forth. The OVD technology detected that hysteresis had quadrupled in one month and found that positioning accuracy was poor.

Although noise problems with steam turbine control valves have existed before, they have become more prominent with nuclear turbines, whose valves range to 20 in. in diameter. Our first

Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve.

In such industries, control valves are an essential component of the systems used to control important operational parameters like pressure, temperature, liquid levels and flow rates.

The pressure control valve consistently seals the battery system against standard pressure fluctuations of
