Design principles and electrical characteristics

The design principle of this product is to attach an electrical signal device (limit switch box) at the top of the butterfly valve worm gear device, which converts the mechanical action of the valve into an electrical signal. Connect the "open" or "close" signal lights of the valve to achieve remote monitoring of the valve's opening and closing status. To ensure the long-term reliability of the valve, the key electrical signal device is selected as an imported APL-210 "limit switch", which complies with UL, CSA, SWMCO, VDE and other standards, with a protection level of IP60 or IP67 (completely dust-proof or splash proof protection).

The power parameters are as follows:

DC: 0.6A125V DC

Communication: 16A250V AC
