Product Details


mechanical valve position feedback limit switch box for Explosion-proof



APL~210N position limit switch is a signal device for the remote control of valve, show the working  condition of valve by the switch, it contains mechanical switch and proximity switch, and widely applies to 

petroleum,  chemical industry, pharmacy, food, electricity, coal gas, pro~environment, metallurgy and paper making  etc.





- The switch is installed separately, convenient maintenance and replacement

- Firm and compact design,

Die-casting aluminum
