YT-1000 YT-1000L YT-1000R Positoner

Overview of YT-1000 YT-1000L YT-1000R Positoner

YT-1000 YT-1000L YT-1000R Positoner is the main accessory of the regulating valve. It is usually used together with the pneumatic regulating valve. It receives the output signal of the regulator, and then uses its output signal to control the pneumatic regulating valve. When the regulating valve acts, the displacement of the valve rod is fed back to the valve positioner through the mechanical device, and the valve position status is transmitted to the upper system through the electrical signal. Function: pneumatic valve The positioner and pneumatic actuator together form an automatic control unit and various control valves. After debugging and installation, they are combined into a pneumatic control valve, which is used in various industrial automation process control fields.

Principle of YT-1000 YT-1000L YT-1000R Positoner

The pneumatic valve positioner is a device that receives weak current signals such as 4 ~ 20mA from the controller or control system and transmits air signals to the pneumatic actuator to control the valve position. It is used together with the pneumatic control valve to form a closed-loop control loop. The DC current signal given by the control system is converted into the air signal driving the regulating valve to control the action of the regulating valve. At the same time, the feedback is carried out according to the opening of the regulating valve, so that the valve position can be correctly positioned according to the control signal output by the system.
