product overview
The electric internal thread ball valve is composed of an angular stroke electric actuator and an internal thread ball valve, suitable for situations where two positions are cut off and adjusted. Electric internal thread ball valveThe connection between the valve body and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can be controlled by inputting a 4-20mA signal and a 220VAC power supply. The internal thread electric ball valve has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action, etc.
Product Features
1. The electric actuator adopts imported original components, which are precise and wear-resistant, with minimal backlash and guaranteed safety;
2. Has dual limit, overheating, and overload protection (optional function);
3. No refueling, no inspection, waterproof and rust proof, and can reduce electromagnetic interference;
4. There is no bracket connection between the ball valve and the actuator, and the integrated external structure is compact, reducing equipment space;
5. An anti-static device is installed between the ball valve and the ball body;
6. Explosion proof design of ball valve stem and fire-resistant structural design;
7. The double-layer valve stem packing meets the valve stem leakage testing requirements of T ü V TA-LUFT in Germany;
Characteristics of actuators
The actuator can directly receive 4-20mADC or 1-5VDC control signals output by computers or industrial instruments, with a 220VAC power supply. Based on the deviation between the valve position feedback signal and the set value, the actuator drive motor is intelligently step adjusted (PID adjustment) to achieve precise positioning of the valve or other device opening that is matched with the actuator, while outputting 4-20mADC position feedback signals. Its core control component, the electronic servo controller, is designed using modern digital technology and DCS/PLC specifications, integrating signal acquisition, processing, feedback, and control. Adopting a unique electronic braking circuit and adding a mechanical damping device to eliminate inertia, it can instantly stop the machine without oscillation during positioning, and the positioning accuracy can reach over 0.3%. Controllable silicon output, fast action time, stable output, high reliability. Small size, lightweight and pleasant, reliable performance, simple matching, high flow capacity, especially suitable for occasions where the medium is viscous, contains particles, and has fiber properties. At present, this valve is widely used in industrial control coefficients in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.
