MK3 Motorized Ball Valve - 1/2"~2"
QUEEN MOTOR VALVE
Description
MK3 motor valve: spring return electric actuator is designed for applications requiring a safe position reset in the event of a power failure. It is especially suitable for 90° rotary butterfly valves, ball valves, and plug valves, making it an ideal choice for emergency operation when power is lost.
• Two power cords wiring. (Same wiring sketch as Solenoid Valve)
• MK3 Actuator are fit for assembling with 2 way or 3 way ball valves.
• MK3 Actuator can set it as emergence shut-off ( power on to open) or set it as emergence open ( power off to close ).
• MK3 are suit to pressure range from 0 - 10 kg*f/cm .
• Acting time 2.5 seconds from close position to open position, vice versa.
• Power failure or electric outage, MK3 are available for manual operation.
• With water proof dust proof aluminum housing.
