VI(D) Series Control Valves

1、 (Pneumatic) actuator adopts VI (M) series multi-spring high strength enhanced actuator, through simple operation, the positive and negative forms can be changed at will in the field; micro-positive pressure protection can effectively protect the springs and diaphragms from corrosion, thus prolonging the service life of the actuator and facilitating the user's use. The design of pipelineless connection between actuator and intelligent valve positioner improves the anti-seismic performance, stability and adjustment accuracy of the control valve, and satisfies the precise adjustment of working conditions.   

2、(Electric) actuator adopts electronic control type, intelligent integrated control type, and intellectualized control communication module, realizes two-way communication between micro-technology and field communication technology, PID regulation, on-line automatic calibration, self-calibration and self-diagnosis and other control technology functions, which improves the stability of process control of control valve. With the adjustment accuracy, it satisfies the precise adjustment of working conditions.
