Plug Type Diverter Valve

Plug Type Diverter Valve is a core pipeline switching device customized for solid material (powder, granular material, powder-granular mixture) conveying systems. Based on the company's years of experience in valve manufacturing and material conveying technology, it uses a "rotary cylindrical valve core" as its core and adopts a three-way layout with one inlet and two outlets or two inlets and one outlet. It can flexibly realize the functions of material flow direction switching, diversion and merging. It also has the advantages of anti-clogging and wear resistance, reliable sealing and convenient operation. It is manufactured in strict accordance with industry standards such as GB/T 9092 and API 598. It is suitable for multiple working conditions from normal pressure to high pressure and is widely used in chemical, metallurgical, new energy, mining, grain processing and other industries. It completely solves the industry pain points such as powder/granular material switching jamming, leakage and high flow resistance, simplifies pipeline layout and improves the operating efficiency of material conveying system.

As a key switching hub in powder/granular material conveying systems, this product's three core functions work together to connect different pipeline systems, enabling flexible material control while ensuring operational stability and ease of use, and adapting to various material conveying process requirements:

Flexible flow direction switching : The material flow direction can be quickly switched by driving the valve core to rotate through the actuator. It is suitable for pipeline layout with one inlet and two outlets or two inlets and one outlet. The pipeline angle can be selected as 30° or 45° according to the requirements. No additional valve combination is required, simplifying the pipeline layout and adapting to the process flow with frequent switching. The valve core action position is accurately detected by the limit detection switch to ensure that the switch is in place.

Efficient diversion and merging : The optimized rotary drum flow channel design can accurately realize the division of one material into two outputs, or the merging of two materials into one output. The flow channel has no dead corners or residues, avoids material accumulation, adapts to the material conveying needs of different flow rates, ensures uniform material distribution, and guarantees the stability of the production process. It is especially suitable for continuous conveying scenarios of powder and granular materials.

Anti-blocking, sealing and leakage prevention : adopts a special sealing structure, and can be configured with a special sealing scheme according to the pressure sealing requirements to achieve tight sealing, effectively blocking material leakage and air entry, avoiding material waste and workshop dust pollution; the rotary drum flow channel is smooth and clean, without protrusions or dead corners, and with a reasonable flow channel cross-section design, it completely eliminates material jamming and accumulation, and is suitable for conveying and switching of high viscosity and easily caking materials.

1. Rotary cylinder valve core, with outstanding anti-clogging performance.

The core adopts a rotary cylinder valve core, and the inner wall of the flow channel is precision polished (polishing precision can reach 400#), smooth and clean, with no dead corners of material residue, which can effectively avoid the jamming and accumulation of powder and granular materials during the switching process. It is suitable for granular materials with multiple particle sizes from 0.1 to 50 mm and various powder materials. The valve core rotates smoothly and is accurately positioned by the limit detection switch. The switching is smooth and suitable for multiple scenarios such as gravity unloading reversal and pneumatic conveying pipeline reversal.

2. Reliable sealing, adaptable to various pressure conditions.

The soft seal or hard seal structure can be configured according to the working conditions. The soft seal uses high polymer materials such as PTFE and PEEK, which are suitable for low pressure and clean media (such as food and pharmaceutical industries) to achieve zero leakage. The hard seal uses wear-resistant and high-temperature resistant materials such as Stellite alloy and tungsten carbide, which are suitable for high pressure conditions. The working pressure can cover atmospheric pressure to high pressure above 0.35MPa. It can operate without leakage and wear for a long time, meeting the sealing requirements of different pressure scenarios.

3. Wear-resistant and durable, with a long service life.

The valve body and rotary cylinder valve core are precision cast from cast steel and stainless steel (304, 316L, CF8/CF8M optional), with a robust structure, high strength and not easily deformed, and a beautiful appearance. The valve core surface is hardened or hard alloy welded (HRC≥55), which can effectively resist the high-speed scouring and wear of powder and granular materials, and is suitable for conveying high-wear materials. The bearing seat adopts an isolation sealing design to prevent material from entering, extend the life of core components, and reduce the later maintenance cost.

4. Easy to operate, quick response and controllable

It supports both manual and pneumatic drive modes. Manual drive is labor-saving and flexible to switch. Pneumatic drive controls the actuator through a solenoid valve, which can achieve rapid switching. It supports remote control and automation linkage, is compatible with industrial automation production lines, and does not require manual on-site operation, which greatly improves production efficiency. The two positions of the valve core are directly detected by the limit detection switch to ensure accurate switching and avoid misoperation.

5. Complete range of diameters, strong installation adaptability

The nominal diameter covers DN50～DN600 (2"～24"), which can meet the material conveying needs of different flow rates and is suitable for large flow powder and granular material conveying scenarios. The interface adopts GB/T 9113 and ANSI B16.5 (150lb) standard flange connection, which can be seamlessly connected with various pneumatic conveying systems, storage equipment and conveying pipelines. It supports horizontal and vertical installation methods. Users can choose the appropriate installation angle according to the needs of the conveying pipeline without complicated modification and has strong adaptability.

6. Easy to maintain and low operating costs

With a modular design, vulnerable parts such as valve cores and seals can be disassembled and replaced individually without dismantling the entire valve, greatly improving maintenance efficiency. The standardized configuration of vulnerable parts makes procurement convenient, and they are wear-resistant and durable, reducing the frequency of replacement. The equipment operates with low vibration and noise, and has a low failure rate, allowing for long-term continuous operation. This significantly reduces downtime maintenance costs and labor input, making it suitable for 24-hour continuous production needs.
