Product introduction
The intelligent valve positioner TS800 is a device that receives a 4~20mA DC current signal from a current output device such as a control room or a signal generator, adjusts the air supply pressure input to the valve actuator in proportion, and precisely adjusts the valve opening.
Product features
Simple and fast automatic setting
Large flow output, accelerating valve control speed (above 100LPM)
Short Stroke Test (PST)
HART communication module (HART version 7)
Mechanical limit switch or inductive switch (option)
Bypass switch (automatic/manual switch)
Fault alarm and self diagnosis function
