The MSP-25 series Smart Valve Positioner 
 The MSP-25 Series smart valve positioner is issued by the receiving controller or control system, 4 ~ 20mA current signal to control the valve opening device. Built-in microprocessor, can accurately control the valve opening, and can perform automatic settings, PID control, the HART communications and other powerful features, which is characterized by: 
 With automatic setting can be automatically set to zero / full scale, the best speed of the executing agency action, the corresponding packing friction coefficient. - 
 Built-in filters, can prevent the blocking of the gas line, but will also prevent gas source acrobatics caused by the locator is not working properly. - 
 Through intelligent communication parameters set locator, including the signal range, the role of the executive body, valve function and sub-process setting. - 
 Define the linear, equal percentage and quick opening flow characteristics. - 
 Straight stroke and rotary through changes corresponding mounting bracket can be realized.
