Product Description

CV3000 series intellectualized control valve using general character and commutative characters modularization design, compact configuration, its characteristic is diverse, track use trim to assembled, can be expected by the customers. Modularization design and both of the double-faced can use valve seat to connect body, enhance wind tight grade and useful time availably, and servicing will be convenient. Accordingly, enhance integration capability of control valves.
ZM10 series multi-spring of pneumatic actuator using modularization design, can instead front to feed back at discretion in scene, and protect spring antisepsis availably, accordingly, protract useful time of actuator, the consumer use it expediently. The actuator and intellectualized electric positioner using no pipe-lines design, improve control valves astigmatic capability, work stability and regulating precision. Satisfy exact regulating of situation.

Working principle
The positioned incept normal signal of electricity or signal of computer, to conversion valve enactment, cylinder actuators beeline displacement track connect set to conversion angle displacement, besides by transducer to measure, feed back to microprocessor.
Microprocessor use the cost of feedback and enactment to compare, after check warp, base warp is different and orientation output PWM( Puise Width Modulation) to piezoelectricity valve, the piezoelectricity valve use PWM(Puise Width Modulation) to regulate the quantity of intake and vent.

Control mode
Control mode using PWM (Puise Width Modulation) to drive:
high speed: when control warp is big, positioner output the signal of link.
Mid-speed: when control warp is not too, output the signal of impulse.
Slow speed: when control warp is small, output the signal of small impulse.
Keep orientation: when control warp is smaller than control valve precision, no signal.
