Introduction: The DQF series electric ball valve consists of a miniature synchronous motor, Japanese imported limit switches, indicator switches, small relays, non-side steel balls, and a mechanical transmission device with large and small gears. It features an iron valve body, a spray-coated casing, and a polytetrafluoroethylene seal, ensuring long-lasting wear resistance. The flanged and threaded connections comply with national standards and can also be made compatible with traditional solenoid valves for easy replacement. The upper indicator disc of the casing can mechanically indicate the actual valve position, and the combination of electrical indicator switches and control indicator lights can accurately reflect the on-site valve position. With exquisite craftsmanship and an attractive appearance, this product is widely used in various process pipelines with large pressure differences, easy clogging, and requirements for rapid opening and closing and cutting. Its superior product characteristics and cost-performance ratio far exceed similar solenoid valve products.
Product Features:

 Characteristics of quick-opening electric ball valves:
    ★ Short opening and closing time, completing the opening and closing action in 3-4 seconds.
    ★ Allows large pressure differences.
    ★ Has a self-cleaning function, easily cutting off various impurities in the pipeline and effectively ensuring the unobstructed flow of the pipeline.
    ★ Excellent sealing performance with double-sided spherical sealing, achieving a zero-leakage standard level.
    ★ Long service life, adopting a new technology driven by an electric quick-opening actuator: only consumes electricity during operation, with zero power consumption when idle, meeting environmental protection design requirements.
    ★ Wide adaptability, with various connection methods available (flanged, threaded).
    ★ Straight-through structure is simple and reliable, with a maintenance-free design.

Product Advantages:

1. The valve motor is a non-burnable miniature synchronous motor;
2. Stainless steel valve core, non-rusting and smooth, ensuring the motor always operates smoothly due to constant load;
3. For medium pressure below 0.1MPa, a cast iron valve body is sufficient to withstand;
4. Polytetrafluoroethylene seal ring, with a temperature resistance of 250°C. Since the medium is at room temperature, the seal ring will not soften or deform. The polytetrafluoroethylene seal ring or felt seal pad contacts the smooth stainless steel valve core, and the friction time is only 2 seconds per cycle during opening and closing actions, resulting in almost zero wear. Practice has proven that the valve seal ring (pad) will not wear for eight years;
5. Transmission gears are oil-free lubricated;
6. The longest-lasting components in the valve are two limit switches produced by Japan's Omron Corporation, one full-open valve position actual signal output switch, and one Omron small relay. Their operating life is all 1 million times, which translates to a service life of more than five years;
7. Installation angle is not restricted;
8. In summary, the DQF electric ball valve is maintenance-free within five years. After five years, simply replace the new micro switches and relays, and the valve can operate normally for another five years;
 

Why can it eliminate traditional air distribution valves? This is because:
1. Ordinary solenoid valves have a service life of only three months when used in frequent inflation applications;
2. Pneumatic solenoid valves have a service life of eight months and require a compressed air pipeline;
3. Pneumatic 0-type ball valves have frequent and random failures of small solenoid valves, requiring a three-unit air source and regular oiling, and also needing a compressed air pipeline;
4. Traditional electric ball valves have long opening and closing times (generally 8-20 seconds), and position signals are prone to drift (occurring after one and a half months). When installed vertically, the main shaft is prone to fracture due to the heavy and drooping actuator head, requiring thick cables for power and signal transmission;
5. Rotary air distributors have high power consumption, monotonous control, and if one nozzle is clogged with powder, the entire machine will be paralyzed, and they also require civil engineering foundations. The power supply for DQF electric ball valves is usually 220VAC50HZ, and the control signal is 220VAC50HZ. It has passive dry contact valve position actual signal output terminals, allowing accurate understanding of the on-site actual valve position switch status in the central control system.
