Type YT-1000L Electro-pneumatic valve positioner is used for operation of pneumatic linear valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.
Smart valve positioner
The intelligent valve positioner is an intelligent process control instrument based on microprocessor technology and adopts digital technology for data processing, decision generation and two-way communication. YT1000 EP Positioner does not require manual adjustment and can automatically detect the zero point, full range, and friction of the regulating valve. Coefficient, automatically set control parameters.
A valve positioner that does not require manual adjustment, can automatically detect the zero point, full stroke, and friction coefficient of the regulating valve, and automatically set the control parameters.
4. For split-range adjustment, two regulating valves operate a set of equipment respectively, one regulating valve receives 4-12mA electric signal, and the other valve receives 12-20mA electric signal.
5. Used to change the flow characteristics. The inherent flow characteristics of the original valve can be realized by a positioner, for example:
(1) The original quick opening characteristic can be changed to linear or equal percentage characteristic by the positioner.
(2) The original linear characteristic can be changed into an equal percentage characteristic by the positioner.
(3) The original approximate equal percentage characteristic can be changed to equal percentage characteristic through the positioner.
Valve Positioner is used for two-position action to become proportional action.
Valve Positioner is used for the reverse action of the valve. Through the positioner, the air-open valve can be changed to air-closed valve, and the air-closed valve can also be changed to air-open valve.
When the length of pneumatic signal pipeline is large, generally ≥150M.
