Product introduction
The flameproof intelligent valve positioner TS900 is a device that receives 4~20mA DC current signals from current output devices such as the control room or signal generator, regulates the air supply pressure input to the valve actuator in proportion, and precisely regulates the valve opening.
Product features
Simple and fast automatic setting of large flow output to speed up valve control (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
