Product Overview 

 Q971 electric valve for two off, adjust the occasion. Valve and actuator connection with direct-connect mode, the electric actuator built-in servo systems, servo amplifier without reprovision, 4-20mA input signal and 220VAC power supply to control operation. A connection is simple, compact structure, small size, light weight, resistance, stable and reliable. Actuator can be configured according to user requirements other UNIC, PSQ, HQ, DHL and other types of electronic electric actuator or GTX, AL and other gas-piston actuator.

 CH series actuators can be directly receiving computer or industrial instruments such as the output of 4 ~ 20mADC or 1 ~ 5VDC control signal, 220VAC power supply, according to the valve position feedback signal and setpoint deviation of the actuator drive more intelligent step motors to adjust (PID adjustment) to achieve with the valve actuator or other device supporting the opening of precise positioning, while the output 4 ~ 20mADC position feedback signal. The core components of electronic servo controller controls the application of modern digital technology, the DCS / PLC specification designed, set signal acquisition, processing, feedback control in one. The use of original electronic braking circuit and additional mechanical damping devices to eliminate inertia, can be instantaneous stop, positioning without oscillation, positioning accuracy of up to 0.3% or more. SCR output, fast time, output stability, high reliability. Small size, light and pleasant, reliable performance, supporting a simple, flow capacity, is particularly suitable for medium thick, containing particles, fibrous nature of the occasion. At present, the valve is widely used in food, environmental, light industry, petroleum, paper, chemicals, teaching and research equipment, industrial control power factor and other industries.
