From the control valve application, the development direction is as follows: a. Small actuator: can reduce costs and improve liquidity b. Sleeve-oriented: the use of sleeve-oriented, is conducive to the right, is conducive to reducing friction, is conducive to noise reduction, there is B. Balanced spool: In order to reduce the actuator thrust or push torque, the use of balanced spool is important, it also improves the dynamic performance of the system d. Integrated spool and valve seat: To overcome the shortcomings of poor sealing seat valve, the same material used in the integration of valve components and seat valve parts, the leakage and unbalance force at the same time minimize. e. Simple flow path: simple flow path, reduced flow resistance, not only can reduce the pressure loss across the valve, but also reduce costs. f. Sealing and Friction: Sealing performance and friction performance are contradictory. Control valve design must not only solve the sealing problem, but also pay attention to the performance indexes such as friction and longevity. Therefore, in recent years, Attention, rotary control valve is widely used g. Reduce noise: a variety of ways to reduce the control valve noise, for example, with noise reduction sleeve and the spool, the use of multi-stage spool, the use of noise reduction board, the use of expansion Etc. h. Adopt the control valve of the same diameter as the pipe and the valve trim to limit the flow capacity: to help reduce the inlet pressure of the valve and the flow rate of the outlet fluid, without the need of installing additional pipe fittings such as the reducer to reduce the cost, Large valve parts, can expand the flow of capacity, through the use of the ability to restrict the flow of the valve trim can be corrected to calculate the caliber of the error too large i.In the era of digital information, will be more intelligent positioner or by digital controller Non-linearity law compensates the non-linearity of the controlled object and will less control the flow characteristics of the control valve to compensate the non-linearity of the controlled object Control valve
