(1)     Without opening cover, the LCD can be checked directly. so positioner condition can be checked visually.

(2)     Owing that 4 control buttons and button main function shall be adjusted in all mode of firmware interface, the using method is very simple.

(3)     Owing that our positioner booth -time takes 0.5 second only, this can be minimized the valve stroke difference and increase system safety.

(4)     Positioner operates normally even though there are sudden changes in supplying pressure and /or high vibration environment.

(5)     The method of auto-calibration is very simple and even beginner can operate it easily.

(6)     As the air consumption is very low, it can be reduced operating cost in large scale plants.

(7)     Our positioner is compatible with most of controllers.

(8)     With HART Communication, Various information of valve and positioner can be checked and processed (Option)

(9)     Analogue feedback output signal makes valve system stable.

(10)   Different valve characteristics can be modified -valve flow characteristics control mode such as Linear, Quick Open, Equal %.

(11)   User can make 18 points, so can make special flow control characteristics.

(12)   Tight Shut-off/on's closeness function can be made setting and can minimize valve leakage.

(13)   PID parameter can be controlled by button operation without many additional communicator.

(14)   Split Range control such as 4~12mA, 12~20mA is possible.

(15)   Positioner's Operating temperature is -30℃ ~ 80℃.

(16)   (Please check "2.5" products specification in case of explosion proof ambient temperature)

(17)   Hand calibration function can set Zero point and Span point manually.

(18)   Through self-diagnosis function, products reliability can be increased.

(19)   It has excellent IP66 enclosure grade.

(20)   There are excellent polyester spray coating which has resistance to corrosion so it is very stable in the corrosion environments.

(21)   Inside structure is Module type and simple to maintain and repair.
