The intelligence of control valves usually takes the following forms:
a. Pneumatic control valve with intelligent valve; Intelligent control valve is a control valve with a microprocessor that can achieve intelligent control functions.
b. Intelligent electric control valve; Pneumatic control valve with fieldbus intelligent valve.
c. It can operate in both direct power supply and intrinsic safety modes, in accordance with the relevant standards of fieldbus.
d. With communication function, it can easily communicate with the upper computer, achieve data exchange and sharing.

Main components: valve body (aluminum body, HT200, QT450, WCB, CF8, CF8M, CF3M), valve plate (ductile iron nickel plating, ductile iron nylon plating, CF8, CF8M, CF3M, 2507, 1.4469, 1.4529, etc.), sealing ring (EPDM, NBR, PTFE, fluororubber, etc.), nominal pressure Ps (MPa): strength test (1.5-2.4), sealing test (1.1-1.76), power pressure: AC220V, AC380V, DC24V

The electric three piece threaded ball valve has a small volume. The electric three piece ball valve is composed of a three part valve shell, which is formed by four longer bolts clamping the middle valve body and ball from both ends. Its advantage is that during maintenance and disassembly, there is no need to disassemble the pipeline threads, and the four bolts can be directly removed. The middle part of the valve body can be taken out. The working principle is also to drive the rotation of the sphere through a 90 degree rotation of the pneumatic actuator to achieve the flow and blockage of the medium. The direct connection between the actuator and the valve body reduces the probability of failure. Suitable for situations where the volume of light industrial machinery is small and the space is narrow.
