CKE700 Electro Pneumatic Positioner

KE700 series electro pneumatic valve positioner is a device to precisely control the valve opening degree with the 4~20mA DC current signal receiving from control system. The pneumatic positioner can be used for single action and double action execution mechanism.

Features

1, Light and exquisite design, no need to replace the body, a variety of air interface, pressure gauge joint which is normed (Rc NPT) and easy to change.

2, Cams are divided into two types: straight stroke and angle stroke, which are easy and convenient to interchange.

3, No need to replace the spring, can both be used by standard range (4 ~ 20mA), divided range (4 ~ 12, 12 ~ DC 20mA).

4,Air consumption is very small.

5,Wide temperature range.

6,Simple structure, easy adjustment and maintenance.
