YT1000R Electro Pneumatic Valve Positioner-Data Sheet (PDF Download)
Type YT-1000R Electro-pneumatic valve positioner is used for operation of pneumatic rotary valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.
Valve positioner
The valve positioner is the main attachment of the pneumatic actuator, which is used with the pneumatic actuator, and the valve positioner has the following use:
1. The valve positioner can improve the linearity of the stem position, overcome the friction of the valve stem, eliminate the effect of the control medium pressure change and the high pressure difference to the valve position, so that the valve position can be properly positioned according to the control signal.
2, the valve positioner can increase the speed of the actuator, improve the dynamic characteristics of the control system.
3. A pneumatic actuator of non-standard signal pressure of 40-200 kPa can be operated at a standard signal pressure of 20-100 kPa.
4, the valve positioner can achieve the above-in-one control valve with a control meter, * Table air conditioning valve load 20-60 kPa signal pressure rear valve take full stroke, second pneumatic adjustment The valve is fully stroke after the positioner is transferred to the signal pressure of 60100 kPa.
5. The valve positioner can achieve a counter action.
6. The valve positioner can correct the flow characteristics of the control valve.
7. The valve positioner can make the two-position actions of the piston actuator and the long stroke actuator becomes a proportional action.
8. After using the electro pneumatic valve positioner, a 4-20 mA signal can be used to operate the pneumatic actuator, an electro pneumatic valve positioner has a dual role of an electro pneumatic converter and a pneumatic valve positioner.
