Rotary Airlock Valve
As a professional and experienced manufacturer, Jiangteng provides Rotary Airlock Valves that offer stable, efficient, and trouble-free operation. Our equipment features exceptional wear resistance and a long service life; furthermore, it can be custom-tailored to meet the specific requirements of various industries and operating conditions. Designed for ease of maintenance, our solutions help you achieve significant cost savings.
The Rotary Airlock Valve is one of the key products designed and manufactured by Jiangteng. As a specialized factory, we produce equipment that serves as a critical safeguard for the stable operation of pneumatic conveying systems, ensuring the consistent and reliable transport of materials.
What Are the Advantages of Our Rotary Airlock Valves?
A reliable rotary valve is crucial for the continuous conveying and air-locking stages of powdery, granular, and other bulk materials. Our products are meticulously designed and manufactured to play a vital role in the overall efficiency and performance of the entire system.
1. Exceptional Durability
For abrasive materials (such as mineral powders or cement), we offer options such as hard-alloy coating on the valve's inner walls and wear-resistant hardfacing on the rotor. These features extend the equipment's service life several-fold, significantly reducing spare parts costs and losses associated with downtime.
2. Reliable Sealing
Jiangteng employs high-precision machining to ensure a rotor clearance of ≤0.25mm, coupled with the selection of premium sealing materials. This effectively isolates positive or negative pressure environments, preventing gas backflow and material leakage, thereby guaranteeing the stability and efficiency of the entire conveying system.
3. Tailored Customization
No two operating conditions are exactly alike. We offer comprehensive customization services—ranging from material selection (stainless steel, ceramics, etc.) and temperature resistance (up to 500°C) to specialized functions (anti-jamming, sanitary cleaning, explosion-proofing)—to perfectly match your specific material characteristics and process environment.
4. Energy Efficiency
Our optimized structural design ensures low vibration and minimal noise during operation. Compared to traditional valves, our rotary drive mechanism is more energy-efficient, helping you reduce long-term operating costs.
5. Simplified Maintenance
Featuring a flanged connection design, installation is quick and effortless. Key components are easily accessible for inspection and replacement, making routine maintenance simple and minimizing both maintenance workload and system downtime.
How Does a Rotary Airlock Valve Work?
A rotary valve operates by utilizing an internal rotor fitted with vanes that rotate at a constant speed to continuously and quantitatively convey material from an overhead hopper to a downstream pipeline or piece of equipment, while simultaneously maintaining airflow isolation. Its core mechanism involves the following steps:
1. Uniform Filling: Material enters through the inlet and falls into the rotating compartments formed by the vanes.
2. Sealed Conveyance: As the rotor turns, the material-filled compartments create a sealed space—thereby performing an "airlock" function—that prevents airflow from passing between the upstream and downstream sides.
3. Smooth Discharge: The material rotates to the outlet port, where it is steadily discharged, driven by either gravity or the airflow.
4. Your Benefit: By utilizing a variable frequency drive (VFD) to adjust the rotor speed, you can easily and linearly control the material feed rate, thereby meeting your precise process proportioning requirements.

FAQ
Q: How should I choose the right model for my factory?
A: This primarily depends on four factors:
Material Characteristics: Density, moisture content, abrasiveness, and corrosiveness.
Operating Conditions: Temperature and pressure.
Functional Requirements: Simple conveying, precise metering, or frequent cleaning.
Installation Space.
Our engineers are available to provide you with free consultation on model selection.
Q: If the material is somewhat damp and prone to clumping, is there a risk of jamming?
A: For such materials, we recommend our anti-jamming design. This design features a unique V-shaped inlet and chamfered vanes, and is equipped with an air venting function; these features effectively prevent material bridging and blockages, ensuring smooth and uninterrupted operation.
Q: Is the maintenance of the Rotary Airlock Valve complicated?
A: Routine maintenance is very simple. It mainly involves periodically (we recommend every 3 to 6 months) checking the gearbox lubricant level, inspecting the seals for wear, and cleaning out any residual material that may have accumulated inside the valve. The equipment is designed to allow for quick opening to facilitate inspection and maintenance.
Q: Can this valve be used for bidirectional conveying?
A: Yes, it can. Our eccentric rotary valve design supports bidirectional sealing. During installation, you simply need to ensure that the motor's direction of rotation aligns with your desired material flow direction, thereby offering greater flexibility in your piping layout.
