Models: DQF65, 80, 100, 125, 150 (Customizable for Non-Standard Specifications)

Introduction: The DQF series electric ball valve consists of a micro-special synchronous motor, Japanese imported limit switches, indicator switches, and small relays, along with a mechanical transmission device featuring a steel ball and gears. It features a steel valve body, a spray-painted housing, and PTFE sealing components for long-lasting wear resistance. Flange and threaded connections comply with national standards and can also be made compatible with traditional solenoid valves for easy replacement. The indicator disk on the upper part of the housing mechanically displays the actual valve position, while the electrical indicator switch combined with the control indicator accurately reflects the on-site valve status. The product boasts exquisite craftsmanship and an attractive appearance. It is widely used in various industrial pipelines requiring rapid switching and shut-off under conditions of high differential pressure and susceptibility to clogging. Its superior product characteristics and cost-effectiveness far exceed those of similar solenoid valve products.
Product Features:

Quick Opening Electric Ball Valve Characteristics:
    ★ Short switching time, completing open/close actions in 3-4 seconds.
    ★ High allowable pressure difference.
    ★ Self-cleaning function, easily cutting off various impurities in the pipeline to ensure smooth flow.
    ★ Excellent sealing performance with double-sided spherical sealing, achieving zero leakage standards.
    ★ Long service life, utilizing new technology in electric quick-opening actuators: consumes power only during operation, zero power consumption when idle, meeting environmental design requirements.
    ★ Wide adaptability, with various connection options available (flange, threaded).
    ★ Straight-through structure is simple and reliable, designed for maintenance-free operation.

Product Advantages:

1. The valve motor is a burnout-resistant micro-special synchronous motor;
2. Stainless steel valve core, rust-free and smooth, ensuring consistent motor load and smooth operation;
3. Cast iron valve body sufficiently withstands medium low pressure below 0.1MPa;
4. PTFE sealing ring withstands temperatures up to 250°C, and since the medium is at normal temperature, the sealing ring does not soften or deform. The PTFE sealing ring or felt sealing pad contacts the smooth stainless steel valve core, with friction time limited to only 2 seconds per cycle during opening/closing, resulting in almost zero wear. Practice proves that the sealing ring (pad) remains unworn for eight years;
5. Transmission gears require no oil lubrication;
6. The components with limited lifespan inside the valve are two limit switches and one fully open valve position real signal output switch from Japanese OMRON, as well as a small OMRON relay. Their operational lifespan is 1 million cycles each, translating to over five years of service;
7. No restrictions on installation angle;
8. In summary, the DQF electric ball valve is maintenance-free for five years. After five years, simply replacing the micro-switches and relay allows another five-year cycle of normal operation;

Why can it replace traditional valves for air distribution? Because:
1. Ordinary solenoid valves used in frequent inflation scenarios last only three months;
2. Pneumatic solenoid valves last eight months and require compressed air pipelines;
3. Small solenoid valves in pneumatic O-type ball valves frequently fail randomly, require air source triple units, regular oiling, and also need compressed air pipelines;
4. Traditional electric ball valves have long opening/closing times (typically 8-20 seconds), position signals are prone to drift (occurring after about a month and a half), and when installed vertically, the heavy actuator head causes the main shaft to break easily, requiring thick cables for power and signal transmission;
5. Rotary air distributors consume high power, have monotonous control, and if one nozzle clogs, the entire machine fails, additionally requiring civil foundation work. The DQF electric ball valve typically uses 220VAC 50Hz for power and control signals, and includes passive dry contact valve position real signal output terminals, allowing accurate monitoring of on-site valve status in the control room.

When placing an order, please follow the instructions below, refer to the specific model and specification catalog, and provide detailed processing information in order to facilitate mutual operations, ensuring prompt and satisfactory service.
1. Specify the model according to the model representation method. If there are special requirements, they must be stated at the time of order; otherwise, the company's standard provisions will apply.

2. If the environment contains explosive gases, it must be stated and must comply with the explosion-proof標(biāo)志 regulations in this manual.

3. Specify the connection size standard, valve stem diameter, and extension length. If the connection dimensions differ from this manual, negotiate with the company for a solution.

4. Clockwise rotation of the handwheel closes the valve. If opposite, it must be specified.

5. For thrust-type valve stem nuts, the threads are generally processed by the user. The company only pre-processes a hole. If processing by the company is required, provide the thread dimensions.

6. The company can also provide electric devices with other speeds according to user requirements.
