Detailed Description
GENERAL DESCRIPTION
ZBTZ linear electric modulating actuator is a new generation electric actuator for control valve. In its design, we have assimilated the strongpoint of the products of the same type we can find at home and abroad. This series of products can be used with model III and model II instruments and model S auxiliary control unit, they can precisely and reliably control gate valve, isolating valve, throttle valve and all sorts of control valves. They can apply to closed-loop control system of industrial process. They mainly come in to service in the area of power station, metallurgy, chemical industry, sewage treatment, ventilation, air conditioning and so on. These products have two models according to working environment: Flameproof model and common model; Two types according to structure and frame: Integrated type and separated type. For the separated type, the digital servo amplifier and the actuator have been installed separately; For the integrated type, the servo amplifier has been installed inside the actuator. The performance of these products meets with the requirements of Std. JB/T8219-1999 Electric Actuators for Industrial-process Measurement and Control Systems. For flameproof model, the performance satisfies the requirements of Std. GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres Part 1: General Requirements and Std. GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres Part 2: Flameproof Enclosure
The product characteristics are as following:
1. Provided with series 51 single-chip as main control unit, the control of electric actuator is more flexible and reliable.
2. Provided with perfect protection circuit, the open and close directions are interlocked to prevent it from motor overheat, over torque and over travel.
3. AC contactor replaced by solid state relay, the valve motor can start 1200 cycles per hour within the range of temperature rise, and service life of valve motor is prolonged.
4. Sealed in bellows or sleeve, and lubricated with thin oil, screw rod and nut of the electric linear actuator will hardly get stuck, and the service life is prolonged.
