YT1000 L Precision Electric-pneumatic Valve Positioner
1000 series Electric-pneumatic Valve Positioner is used with the pneumatic control valve to form a closed loop control loop. The DC current signal given by the control system is converted into a gas signal that drives the regulating valve to control the action of the regulating valve. At the same time, feedback is made according to the opening degree of the regulating valve, so that the valve position can be correctly positioned according to the control signal outputted by the system. The electric positioner can be used for single-acting (spring-return type) and double-acting pneumatic actuators.
Product Definition
1000 series Electric-pneumatic Valve Positioner is used with the pneumatic control valve to form a closed loop control loop. The DC current signal given by the control system is converted into a gas signal that drives the regulating valve to control the action of the regulating valve. At the same time, feedback is made according to the opening degree of the regulating valve, so that the valve position can be correctly positioned according to the control signal outputted by the system. The electric positioner can be used for single-acting (spring-return type) and double-acting pneumatic actuators.
Installation of Electric-pneumatic valve positioners: This series is adjustment type and is designed for double-acting or single-acting actuators with input and output 4-20 mA feedback signals. The pneumatic actuator is equipped with an electric-pneumatic valve positioner and bracket, linking the feedback lever through the pinion NAMUR slot, which is fastened by 4 bolts. The air source pipeline can be connected to realize the adjustment control.

Smart Valve Positioner uses sensor technology for temperature and position compensation, and has the outstanding characteristics of anti-vibration capacity up to 10g, 10-150Hz. Temperature range -40~+85°C. Through HART or Profibus/FF communication interface, real-time connection between the scene and the control room can be established. Parameter adjustment and status monitoring can be carried out. The output characteristics of free configuration can improve the output characteristics of the ball valve/butterfly valve to the greatest extent.
Explosion-Proof Smart Valve Positioner
The Smart Explosion-proof Valve positioner is a digital field control instrument used to precisely adjust the opening of pneumatic control valves in hazardous explosive environments. It receives the 4-20mA DC analog control signal from the DCS system and converts the electrical signal into a corresponding pneumatic output pressure to drive the actuator, so that the actual valve opening is consistent with the control set value.
