BLAQ Small Size Electric Ball Valve

·Receiving directly output signal such as 4 ~ 20 mA DC or 1 ~ 5 V DC control signal from computer or industrial instrument, compared the set value according to the valve position feedback signal, to smart actuators interval adjustment (PID), so as to realize the valve accurate positioning, at the same time output 4 ~ 20 mA DC position feedback signal.

·Small volume, light, reliable performance, simple invention, large flow capacity.

·Particularly suitable for thick medium , including particle and fiber properties.

·Widely used in industrial control system such as cement, food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power industries.
