Flap Diverter Valve

Hanye Flap Diverter Valve is a smooth reversing control device customized for fluid, powder, and granular material conveying systems. Leveraging the company's years of experience in valve manufacturing and fluid control technology, it uses a rigid swashplate valve core as its core, employing a three-way layout with one inlet and two outlets or two inlets and one outlet. The actuator drives the swashplate to rotate, achieving media flow direction switching. It boasts advantages such as smooth reversing, reliable sealing, anti-clogging and wear-resistant properties, and a simple structure. Manufactured in strict accordance with GB/T 9092, API 598, and ISO 4401 standards, it is suitable for various operating conditions from normal to medium-high pressure. It is widely used in industries such as construction machinery, mining equipment, chemical, metallurgy, shipbuilding, and automated production lines, completely solving industry pain points of traditional directional valves such as large reversing impact, easy leakage, material jamming, and cumbersome maintenance. It simplifies pipeline layout and improves system stability and controllability.

As a smooth reversing hub in a media conveying system, this product is based on "swing plate-type precise reversing," with three functions working together to connect the conveying pipeline and the actuator, achieving efficient media control while ensuring stable operation and ease of use, and adapting to complex process requirements in multiple scenarios:

Smooth and precise reversing : Adopting an integrated rigid swing plate valve core, precision machined and molded, the swing plate is driven to rotate smoothly by a pneumatic, manual or electric actuator. The reversing angle can be precisely controlled (0°~90°), without impact or jerking, suitable for working conditions that require smooth reversing; It can flexibly realize one inlet and two outlets or two inlets and one outlet flow direction switching. The swing plate is accurately positioned, without jamming or deviation, avoiding media loss or equipment failure caused by reversing deviation. It is suitable for multiple scenarios such as hydraulic systems, pneumatic conveying systems, and fluid conveying pipelines.

Anti-clogging and anti-accumulation : The swing plate valve core adopts a flat streamlined design, and the inner wall of the flow channel is precision polished (polishing accuracy can reach 400#), which is smooth and clean, without obvious protrusions and dead corners. It can effectively avoid the accumulation and jamming of powder, granular materials or viscous fluids, and is suitable for granular materials with a particle size of 0.1~50mm and various fluid media. During the rotation of the swing plate, it can scrape off the slightly adhered material on the inner wall of the flow channel, further preventing material accumulation and pipe blockage, and completely eliminating the problem of material blockage and downtime. It is suitable for mining, chemical and other dusty and high viscosity media scenarios.

Reliable sealing and leak prevention : Adopting a fitting sealing structure, the swing plate and valve seat fit tightly together. The sealing components are made of high-pressure resistant, wear-resistant, and aging-resistant materials such as FKM (fluororubber), PTFE, and NBR (nitrile rubber), which can be flexibly selected according to the characteristics of the medium to achieve ANSI Class VI zero leakage. For high-pressure and high-wear conditions, a hard seal structure (Stellite alloy, tungsten carbide) can be configured to effectively prevent media leakage and air ingress, avoiding media loss, equipment damage, and workshop dust pollution, and is suitable for long-term stable operation in medium and high pressure scenarios.

1. The swing valve core design ensures smooth and shock-free reversing.

The core adopts an integrated rigid swing plate valve core, made of high-strength alloy material and precision-machined by CNC. The swing plate has uniform thickness and precise center of gravity. Combined with a buffer positioning mechanism, the reversing process is smooth, shock-free, and noiseless, which can effectively protect the actuator and pipeline and avoid equipment damage caused by reversing impact. The reversing response speed is controllable (adjustable from 0.8 to 2 seconds), which can be adapted to frequent reversing conditions and also meet the requirements of high-precision and smooth reversing. It is suitable for automated production lines, precision hydraulic systems and other scenarios with high requirements for reversing stability.

2. Anti-clogging and wear-resistant, suitable for multiple media and various working conditions.

The valve body and sway valve core are precision cast from cast steel or stainless steel (304, 316L, CF8/CF8M optional). Some lightweight models use high-strength aluminum alloy, balancing lightweight and durability, and are suitable for harsh environments such as marine salt spray, high humidity and high temperature, and high dust. The valve core surface is hardened or hard alloy welded (HRC≥55), with excellent wear resistance, corrosion resistance and impact resistance, which can effectively resist the high-speed scouring of powder and granular materials and the erosion of corrosive fluids. The streamlined flow channel design eliminates dead corners for material residue, and is suitable for various media such as hydraulic oil, mineral oil, chemical fluids, powder, and granular materials, and is suitable for high wear and strong corrosion conditions.

3. Simple structure and strong installation adaptability.

Featuring an integrated and streamlined design, this valve is simpler and smaller in size than traditional directional control valves, requiring less installation space. It is particularly suitable for space-constrained environments such as ship engine rooms, construction machinery, and small automated production lines. The nominal diameter ranges from DN50 to DN500, and the interface adopts GB/T 9113 and ANSI B16.5 standard flange connections, allowing seamless integration with various pneumatic conveying systems, hydraulic systems, conveying pipelines, and actuators. It supports both horizontal and vertical installation methods without complex modifications, offering excellent adaptability and flexibility to meet different pipeline layout requirements.

4. Easy to operate and low maintenance cost

It supports manual, pneumatic, and electric drive modes. The manual drive features an ergonomic handle design, making operation effortless and flexible, allowing for quick manual intervention in emergencies. The pneumatic and electric drives enable remote control and automated linkage, adapting to industrial automated production lines and eliminating the need for on-site manual operation, significantly improving operational efficiency. The modular design allows for the individual disassembly and replacement of vulnerable components such as the swing plate and seals, eliminating the need to dismantle the entire valve, thus improving maintenance efficiency by more than 50%. The standardized configuration of vulnerable parts facilitates procurement, ensures wear resistance and durability, reduces replacement frequency, and results in low vibration and a low failure rate during equipment operation, enabling long-term continuous operation.

5. High pressure withstand, stable and reliable operation.

After high-pressure strength and fatigue testing, the working pressure can cover atmospheric pressure up to 16MPa, and it can be adapted to medium and high pressure conditions of Class 600 (about 10MPa). The temperature range is -30℃ to 400℃. It can operate stably for a long time under complex working conditions with high temperature, high pressure and strong vibration without deformation or leakage. The swing plate valve core adopts a rigid connection structure and is equipped with a precise limit device, which ensures firm positioning and avoids reversing deviation caused by medium pressure fluctuations. At the same time, it ensures system pressure stability and avoids air pressure and hydraulic pressure fluctuations caused by reversing.

6. Highly compatible, adaptable to the needs of multiple industries.

It can be seamlessly integrated with our pneumatic conveying systems, hydraulic systems, metering equipment, and actuators, and is suitable for the process requirements of various industries such as engineering machinery, mining, chemical, shipbuilding, and automated production lines. It supports non-standard customization and can adjust the swing plate structure, sealing material, nominal diameter, and switching speed according to the requirements of media characteristics, reversing frequency, installation space, and drive method to meet the personalized working conditions of customers. At the same time, it complies with international hydraulic standards and is easy to integrate with multi-brand systems.
