BLUETOOTH VALVELimitorque MX and QX valve actuators along with MX/QX dashboard software allow wireless communication via Bluetooth. Limitorque QX is a quarter-turn, smart, electronic valve actuator. It uses brushless DC motors to eliminate sparks, reduce mechanical and electrical noise, and dissipate heat better than DC motors with brushes. Unique to the quarter-turn industry, a brushless-actuator design lasts longer than conventional motors and allows for more accurate positioning.
