Yamatake AZBIL positioner is used with pneumatic diaphragm control valve

4. Simultaneous application of single-acting/double-acting actuators (double-acting function is optional)

With a double-acting amplifier, the SVP can be used with double-acting actuators. The opening signal transmission function can be added, and the AVP300 can monitor the action of the regulating valve in the instrument room through the additional opening signal transmission function (4-20mADC or DE). The opening signal transmission circuit needs to be separated from the input signal line, so it is a 4-wire instrument.

5. Easy maintenance

The electrical components are completely isolated from the air line, so it is easy to maintain the air line on site, and the A/Mdigital positioner company - Hiltech switch is equipped as standard, so it is easy to check the operation of the control valve.

(1) Automatic setting: its automatic setting software is a fully automatic configuration program. Unlike other brands of functional locators, no external equipment is required, and no computer or other communicator is required to perform basic configuration. The program can be run at the touch of a switch,

(2) Field intelligent communication: Yamatake's field intelligent communication device (sfc) can be matched with all Yamatake field intelligent instruments, so it can be used for intelligent communication of calibration and configuration.

(3) Reduce spare parts inventory: Since all technical parameters can be changed through software configuration, so. A small amount of spare parts inventory can be guaranteed.

6. High reliability

(1) Seat sealing: If the input signal is lower than the preset value, the seat tight sealing function will completely close the valve. This enhances the complete closing capability of the valve.

(2) Self-diagnosis: The self-diagnosis function can check the status of the positioner at any time and issue an alarm when a fault occurs.

(3) Input range: it can be set to any range value for split range.

(4) Flow characteristics: linear, equal percentage, quick opening or custom user characteristics

(5) Actuator type: single-acting or double-acting actuator (optional double-acting amplifier is required), opening transmission (the signal can be transmitted in proportion according to the valve opening signal. The valve opening can be monitored in the control room) .

7. Easy to use

1. Automatic setting: The automatic setting function is a fully automatic configuration program that can specify the actuator and adjust the zero and span of the valve. You can easily open the program with an external switch, so valve adjustments can be performed quickly and safely, even in hazardous areas.

High reliability

2. Seat sealing: If the input signal is lower than the pre-set value, the seat tight sealing function will completely close the valve. This enhances the complete closing capability of the valve.

3. Self-diagnosis: The self-diagnosis function can check the status of the positioner at any time and issue an alarm in case of failure. A single model is available for multiple sizes, and you can change settings without replacing any parts. A single model can be retrofitted to suit any application.

4. Input range: can be set to any range value for split range.

5. Flow characteristics: linear, equal percentage, quick opening or custom user characteristics

6. Actuator type: single-acting or double-acting actuator (optional double-acting amplifier is required), opening transmission (the signal can be transmitted in proportion according to the valve opening signal. The valve opening can be monitored in the control room).
