Product Detail

Electrical-pneumatic valve locator electric valve localizer that is incompatible with actuators, and receipt 4~20mA DC signal

Electric valve positioner

CHX-1000 electric valve localizer



CHX-1000 electric valve localizer	CHX1000Lwith signal feedback

CHX-1000 electric valve localizer

Summary

CHX-1000 electric valve localizer that is incompatible with actuators, and receipt 4~20mA DC current signal from controller or control system, then transfer into air pressure, which is delivered to pneumatic actuators to control valve's location.

Features

1. Without covibration in 5~200Hz

2. It can be easily converted between direct action and reaction, single action and double action

3. For small actuators that can be passed through narrowing locator throttling to prevent vibration

4. Low air consumption, better economy

5. 1/2 split range available by simple part changing
