From the view of the control valve application, the direction of development is as follows:

Small executive agency: it can reduce the cost and improve the ability of circulation.

Sleeve guide: the use of sleeve guide, conducive to the middle, is conducive to reducing friction, is conducive to noise reduction, and is conducive to the exchange of flow characteristics.

Balance valve core: to reduce the thrust or thrust of the actuator, it is important to use a balanced valve core, and it also improves the dynamic performance of the system.

Integrated spool and valve seat: in order to overcome the disadvantage of poor sealing performance of two seat valves, we use the same material integrated valve core and valve seat to form the valve internals, and reduce the leakage and unbalanced force to the minimum.

Simple flow path: the flow path is simple and the flow resistance is reduced, which can not only reduce the pressure loss at both ends of the valve, but also reduce the cost.

Seal and friction: seal performance and friction performance are two aspects of contradiction, control valve design should not only solve the problem of sealing, friction and life performance also must pay attention to the study of the stuffing box and packing structure to get attention, rotary type control valve is widely used

Noise reduction: using a variety of ways to reduce the control valve noise, for example, the noise of the sleeve and spool by multi-stage valve, the noise reduction limiting plate, the expander etc.

With the same diameter pipeline control valve and limit the flow capacity of the valve parts: to reduce the valve entrance pressure and outlet flow rate, no need to install additional different diameter pipe fittings, which is conducive to reducing costs, by changing the flow capacity of the valve, can be extended through the selection of flow capacity, flow capacity limit valve in a correct calculation of large caliber error

In the era of digitalized information, more intelligent valve positioners or digital controllers are adopted to realize nonlinear laws, which compensate for the nonlinearity of controlled objects. Less control valve flow characteristics are used to compensate for the nonlinearity of controlled objects.

The material of valve internals varies with temperature. Therefore, we should consider the influence of thermal expansion at different temperatures, and also consider the change of pressure level under high temperature. We should consider the corrosion resistance and fatigue resistance of materials.
