Valve positioner is an automatic device used in pipeline system, which is mainly used for real-time monitoring and control of valve position. The following is a detailed answer about the valve positioner:

1. Definition and function

V18345-2020150001 Valve positioner is the main accessory of the regulator, it accepts the output signal of the regulator, and then uses its output signal to control the pneumatic regulator. When the regulating valve is operated, the displacement of the valve stem is fed back to the valve positioner through the mechanical device, and the valve position is transmitted to the upper system by electrical signal. Its main functions include:

Monitor and control valve position in real time to ensure the normal operation of piping system.

Increase the output power of the regulating valve and reduce the transmission lag of the regulating signal.

Speed up the movement of the valve stem and improve the linearity of the valve.

Overcome the friction of the valve stem and eliminate the influence of unbalanced force to ensure the correct positioning of the regulating valve.

Apply

V18345-2020150001 Valve positioners are commonly used with various types of valves, such as ball valves, butterfly valves, globe valves, etc. Its application range is wide, including petroleum, chemical industry, electric power, metallurgy, environmental protection and other fields.

Fourth, the principle of action

The V18345-2020150001 Valve positioner measures valve position information through sensors and sends this information to the control room. The operator in the control room can monitor the position of the valve in real time through the control system and control it remotely. At the same time, the valve positioner can also offset the unbalanced force caused by medium pressure fluctuations according to the valve stem friction and other factors when the regulator works, so that the valve opening corresponds to the output signal of the control room.
