The electric valve positioner YT-1000L is a device that accepts 4~20mA DC current signal from the controller or control system and delivers air to the linear actuator to control the position of the valve.The electric valve positioner is the main accessory of the regulating valve. It is usually used with the pneumatic regulating valve. It accepts the output signal of the regulator and then controls the pneumatic regulating valve with its output signal. When the regulating valve is actuated, the displacement of the valve stem is The mechanical condition is fed back to the valve positioner, and the valve position condition is transmitted to the upper system through the electrical signal.
◈ It is used for important adjustment system with high adjustment quality to improve the positioning accuracy and reliability of the regulating valve.
◈ When the medium to be tuned is a viscous fluid or contains a solid suspension, the positioner can overcome the resistance of the medium to the movement of the valve stem.
◈Used to improve the flow characteristics of the regulating valve.
◈When the medium to be adjusted is high temperature, high pressure, low temperature, toxic, flammable, and explosive, in order to prevent external leakage, the packing is often pressed very tightly, so the friction between the valve stem and the packing is large, and the positioner is used at this time, can overcome time lag.
◈Temperature:-20 to 70 ℃
◈Max pressure:1 Mpa
