The development direction of the regulating valve is mainly intelligent, standardized, refined and miniaturized, rotating and safety.

1. Intellectualization and standardization: the intellectualization and standardization of the control valve have been put on the agenda, and the intellectualization mainly adopts the intelligent valve positioner. The intelligent valve positioner has the functions of self diagnosis and remote communication, which makes the management of the regulating valve convenient and fault diagnosis easy. The intelligent valve positioner can not only change the flow characteristics of the regulating valve conveniently, but also provide the control quality of the control system. Therefore, the requirements for the flow characteristics of the regulating valve can be simplified and standardized. In addition, the intelligent valve positioner is based on HART communication protocol, so that the control function can be realized at the field level, the danger can be dispersed, and the control can be more timely and faster. The control valve is mainly embodied in the modularization of various parts, so when the control valve needs to be repaired and replaced, only some parts need to be replaced, which greatly saves the maintenance cost and time.

2. Refinement and miniaturization: refinement and miniaturization are mainly reflected in: adopting precise and miniaturized actuator to reduce valve volume and weight; changing flow path structure to change linear displacement into angular displacement.

3. Rotation: because of the advantages of rotary control valves, such as ball valves and butterfly valves, such as small relative volume, small flow resistance, large adjustable ratio, good sealing performance and large circulation capacity, the proportion of rotary valves is increasing in the new varieties of control valves, especially in large-diameter pipes, ball valves and butterfly valves are widely used for adjustment.

4. Safety: the safety of instrument control system has been paid attention to in all aspects, and the requirements of safety instrument system (SIS) for regulating valve are also higher and higher, which are mainly reflected in: the requirements for the diagnosis and treatment of the fault information of regulating valve are improved; the requirements for timely, reliable and safe operation of regulating valve used in emergency stop system or safety interlock system are put forward to ensure these regulating valves It can react sensitively and accurately; for the regulating valve used in the dangerous place, the certification procedure shall be simplified; similar to the safety of other field instruments, for the safety of the regulating valve, the explosion-proof technology, fire prevention technology, increased safety technology, intrinsic safety technology, spark free technology, etc. can be used.

5. Energy saving: to reduce energy consumption and improve energy utilization rate is one of the development directions of regulating valves. The main methods are: to adopt the regulating valve with low pressure drop ratio; to adopt the self operated regulating valve; to adopt the electric regulating valve; to adopt the piezoelectric positioner; to adopt the valve core structure with balance structure, so as to reduce the thrust or torque of the actuator; to adopt the frequency conversion technology instead.

6. Environmental protection: environmental pollution has become a public hazard. The environmental pollution caused by regulating valve mainly includes the noise and leakage of regulating valve, among which the noise pollution is more serious.
