Pendulum Diverter Valve

The Pendulum Diverter Valve is a high-efficiency reversing control device specifically designed for fluid, powder, and granular material conveying systems. Leveraging the company's years of experience in valve manufacturing and fluid control technology, it utilizes a "swinging hammer valve core" as its core, employing a three-way layout with one inlet and two outlets or two inlets and one outlet. It achieves rapid reversing through the combined action of the pendulum's gravity and the media's thrust. It boasts advantages such as sensitive reversing, anti-clogging and wear-resistant properties, reliable sealing, and a compact 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 such as jamming, slow reversing, easy leakage, and cumbersome maintenance of traditional reversing valves. It simplifies pipeline layout and improves system operating efficiency and stability.

As a highly efficient reversing hub in media conveying systems, this product is based on "pendulum-type rapid reversing," with three functions working together to connect the conveying pipeline and the actuator, achieving precise media control while ensuring stable operation and ease of use, and adapting to complex process requirements in various scenarios.

Quick pendulum reversal : It adopts an integrated pendulum valve core, relying on the dual action of the pendulum's own gravity and the medium thrust, and can achieve quick reversal without a complex drive mechanism. The reversal response time is ≤0.5 seconds, which is suitable for frequent reversal conditions. It can flexibly realize one inlet and two outlets or two inlets and one outlet flow direction switching. The pendulum is accurately positioned, without jamming or deviation, avoiding medium loss or equipment failure caused by reversal lag. It is suitable for hydraulic systems, pneumatic conveying systems and other scenarios that require reversal speed.

Anti-clogging and anti-accumulation : The pendulum valve core adopts a streamlined design with no obvious protrusions or dead corners. The inner wall of the flow channel is precision polished, smooth and clean, which can effectively prevent the accumulation and jamming of powder, granules or viscous fluids. It is suitable for granules with multiple particle sizes from 0.1 to 50 mm and various fluid media. The pendulum can generate slight vibration during the swing process, further preventing material adhesion and completely eliminating the problem of material blockage and shutdown. 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 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, effectively blocking the external leakage of the medium and the entry of air, avoiding medium loss, equipment damage and workshop dust pollution; For high pressure conditions, a hard seal (Stellite alloy, tungsten carbide) structure can be configured to adapt to long-term stable operation in medium and high pressure scenarios.

1. Pendulum valve core design for sensitive and efficient directional switching.

The core adopts an integrated pendulum valve core, which is precisely machined by CNC. The center of gravity of the pendulum is accurately matched. Combined with the medium thrust assistance, it can achieve a second-level rapid reversing. The response speed is far superior to that of traditional reversing valves. It is suitable for processes with frequent reversing (such as automated production lines and hydraulic systems of engineering machinery). The pendulum adopts a rigid connection structure, which swings smoothly, positions accurately, and has no reversing deviation. It avoids the decline in production efficiency or equipment failure caused by lag. At the same time, it does not require complex drive components and has a simple and reliable structure.

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

The valve body and the pendulum valve core are precision cast from cast steel and stainless steel (304, 316L, CF8/CF8M optional). Some models use high-strength aluminum alloy, which takes into account both lightweight and durability, and can be adapted to harsh environments such as marine salt spray, high humidity and high temperature[4][6]. The valve core surface is hardened or hard alloy welded (HRC≥55), which has excellent wear resistance, corrosion resistance and impact resistance, and can effectively resist the high-speed scouring of powder and granular materials and the erosion of corrosive fluids. The streamlined flow channel design has no dead corners for material residue, and is suitable for various media such as hydraulic oil, mineral oil, chemical fluid, powder, and granular materials, and can take into account high wear and strong corrosion conditions.

3. Compact structure and strong installation adaptability.

It adopts an integrated compact design, which reduces the volume by more than 40% compared with traditional directional valves, and occupies little installation space. It is especially suitable for space-constrained scenarios such as ship engine rooms, engineering machinery, and small automated production lines. The nominal diameter covers DN50~DN500, and the interface adopts GB/T 9113 and ANSI B16.5 standard flange connection, which can be seamlessly connected with various pneumatic conveying systems, hydraulic systems, conveying pipelines and actuators. It supports multiple installation methods such as horizontal and vertical, without complicated modification, and has strong adaptability, which can flexibly adapt to different pipeline layout requirements.

4. Easy to operate and low maintenance cost

It supports both manual and pneumatic drive modes. The manual drive adopts an ergonomic handle design, which is easy to operate and flexible to switch. It can quickly intervene manually in an emergency. The pneumatic drive can realize remote control and automated linkage, adapt to industrial automated production lines, and does not require manual on-site operation, which greatly improves the operating efficiency. It adopts a modular design, and vulnerable parts such as pendulum and seals can be disassembled and replaced separately without the need to completely remove the valve, which improves maintenance efficiency by more than 50%. The vulnerable parts are standardized and easy to purchase. They are wear-resistant and durable, reducing the frequency of replacement. The equipment has low vibration and low noise during operation, low failure rate, and can run continuously for a long time.

5. High pressure withstand, stable and reliable operation.

After high pressure strength test and fatigue test, the working pressure can cover atmospheric pressure up to 16MPa, and can be adapted to Class 600 (about 10MPa) medium and high pressure conditions. The temperature range is -30℃~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 [5][6][9]. The pendulum valve core adopts a buffer positioning design to reduce the impact and noise during the switching process, extend the service life of the equipment, and at the same time ensure the stability of the system pressure and avoid air pressure and hydraulic fluctuations caused by switching.

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

It can be seamlessly integrated with our pneumatic conveying system, hydraulic system, metering equipment and actuators, and is suitable for the process requirements of multiple industries such as engineering machinery, mining, chemical, shipbuilding and automated production lines. It supports non-standard customization and can adjust the pendulum structure, sealing material and nominal diameter according to the medium characteristics, reversing frequency and installation space requirements 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.
