IP66 Electric Valve Actuator , Electrical Valve Positioner CHX-1000
CHX-1000 Electrical valve positioner
CHX -1000R electric pneumatic positioner is used for rotary operation of pneumatic rotary valve actuators by means of electrical controller or control systems with an analog output signal of 4 to 20 MA or split ranges
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 what transfer to the actuator which connect with it , in order to control value position .
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
