Introduction

The diverter valve is also called the speed synchronization valve. It is a general term for diverter valves, collecting valves, one-way diverter valves, one-way collecting valves and proportional diverter valves in hydraulic valves. Synchronous valves are mainly used in dual-cylinder and multi-cylinder synchronous control hydraulic systems. There are many ways to achieve synchronous motion, but among them, the synchronous control hydraulic system using diverter and collector valves-synchronous valves has many advantages such as simple structure, low cost, easy manufacturing, and high reliability. Therefore, synchronous valves have been widely used in hydraulic systems. The synchronization of diverter and collector valves is speed synchronization. When two or more cylinders are subjected to different loads, the diverter and collector valves can still ensure their synchronous motion.

Basic Functionality of a Diverter Valve

The basic structure of the diverter valve includes a fixed throttle hole, a variable throttle port of the pressure reducing valve, a valve body, a pressure reducing valve and a spring. Among them, two fixed throttle holes of equal area are used as flow sensors to convert the two load flows into corresponding pressure differential values. These pressure differential values will be fed back to the common pressure reducing valve core, and the pressure reducing valve core will be driven to adjust the flow after comparison, so that the load flows of the two paths tend to be equal.

When the oil of the hydraulic system enters the diverter valve, it will be divided into two paths, passing through two fixed throttle holes of equal area respectively. These two throttle holes convert the flow into pressure differential values, which are then fed back to the pressure reducing valve core. If the load flows of the two paths are not equal, the pressure reducing valve core will move under the action of asymmetric hydraulic pressure, thereby changing the size of the variable throttle port and adjusting the flow until the load flows of the two paths are equal. In this way, the speed of the two actuators can be synchronized or a certain proportional relationship can be maintained.

Key Functions of Diverter Valves

‌Equal flow split‌

The splitter valve can supply the same flow from the same oil source to two or more actuators in the hydraulic system, ensuring that the speeds of these actuators remain synchronized. This is particularly important when multiple actuators are required to perform the same action at the same time.

‌Proportional split‌

In addition to equal flow splitting, the splitter valve can also supply flow to two actuators in a certain proportion, thereby achieving a fixed ratio relationship in speed. This function is very useful in systems that require precise control of the movement speeds of multiple actuators.

‌Synchronous control‌

The splitter valve (also known as the synchronization valve) is mainly used in dual-cylinder and multi-cylinder synchronous control hydraulic systems. The splitter valve can ensure that multiple hydraulic cylinders can still maintain synchronous movement when subjected to different loads, thereby improving the stability and reliability of the system.

‌Simple structure and low cost‌

The design of the splitter valve usually has the characteristics of simple structure, low manufacturing cost and high reliability, which makes it widely used in hydraulic systems.

‌Flow combining function‌

The flow dividing and combining valve not only has the flow dividing function, but also has the flow combining function, which can collect equal flow or proportional return oil volume from two actuators, further ensuring speed synchronization or fixed ratio relationship.

Common Types of Diverter Valves

‌Fixed diverter valve‌: This type of diverter valve has a fixed structure and does not adjust with flow changes. It can be further divided into two structures: reversing piston type and hook type.

‌Adjustable diverter valve‌: This diverter valve can adjust the flow distribution ratio as needed, and is suitable for occasions where precise flow control is required.

‌Self-adjusting diverter valve‌: This diverter valve can automatically adjust according to flow changes to ensure the stability of flow distribution.

In addition, diverter valves can also be divided into equal flow type and proportional flow type according to the flow distribution method. The proportional flow type often uses a 2:1 flow distribution method.

Electric vs. Mechanical Diverter Valves

Homemade diverter valve 

The valve core position is controlled by manually operating a handle or clump to achieve fluid diversion and inflow direction control. This type of valve is easy to operate and suitable for simple hydraulic systems.

Electric diverter valve 

The valve core position is controlled by electrical factors similar as motors or solenoid valves to achieve automatic control. This type of diverter valve has a fast response speed and is suitable for hydraulic systems that bear precise control.

Operations Across diligence

Hydraulic system

Diverter valves are used in hydraulic systems to control the inflow direction of hydraulic oil painting and control hydraulic selectors similar as cylinders and hydraulic motors. This includes construction ministry similar as excavators, payload, bulldozers, and process control similar as  nonstop casting, rolling and cooling in metallurgical outfit.

Curvaceous outfit

In curvaceous outfit, diverter valves control the inflow direction of compressed air so that curvaceous factors similar as cylinders can act according to a destined program. This enables curvaceous systems to achieve high- speed rotation and high- effectiveness  product.

Chemical process

In chemical processes, diverter valves not only control the flux direction of fluids, but also handle harsh conditions analogous as sharp fluids, high temperatures or high pressure surroundings. This requires the material selection and design of diverter valves to be largely adaptable and reliable.

Material conveying

Diverter valves are also used in pneumatic conveying systems, especially in positive and negative pressure conveying, to guide paraphernalia in different directions. This includes the conveying of cream paraphernalia analogous as cement and lime, as well as coal cream conveying, stovepipe gas dust dumping and other operations.

Automotive Industry

In the automotive sedulity, diverter valves are used to control steering systems, suspension systems, and braking systems to meliorate the handling and safety performance of the vehicle.

Common Issues and Conservation

1. Synchronization failure

2. Large synchronization error

3. Abnormal movement of the chooser end point

Conservation

Regular examination

Check the working status of the diverter valve to ensure that it works generally and flexibly without abnormal sounds or leakage.

Conservation of sealing rings and sealing shells

Regularly check and replace worn and aged corridor.

Lubrication treatment

For diverter valves that have not been used for a long time, lubrication treatment should be performed to ensure their normal operation.

Safe operation

When maintaining the diverter valve, the motorist should close the flux of the corresponding medium and set up obvious safety warning signs in the working area.

Concluding the Right Diverter valve 

When concluding a diverter valve, there are several pivotal factors to consider to ensure system performance and effectiveness.

Diverter rate

Diverter valves can achieve different diverter rates by changing the size of the internal perforation. Choose the applicable diverter rate predicated on your operation conditions. For illustration, if a 12 diverter rate is demanded, where one bay flux is twice the flux of the other, also a diverter  valve with the corresponding perforation arrangement should be named.

Operations

Diverter valves are used in situations where two or further pickers(analogous as cylinders) need to operate synchronously. Make sure the diverter valve is suitable for your synchronization system needs, especially in operations where weight differences may beget problems.

Use conditions

The parameters of the pickers need to be harmonious and fed by the same pump. At the same time, the input flux of the diverter valve should be within the range handed in the product canon to  ensure diverting delicacy and normal operation of the valve.

Cargo pressure effect

In diverter mode, the end with advanced weight pressure will affair more flux. Understanding this point can help you better design the system and take measures, analogous as installing a replenishing valve, to address possible cumulative error problems.

System cleaning and conservation

Choosing a one- piece cast ball draw and a reasonable sealing design can reduce the conservation conditions of the system. Such a design can help impurities analogous as dust from entering the  valve, thereby reducing the frequency of conservation and cleaning.

Conclusion

Diverter valves are considerably used in various hydraulic systems that need to achieve synchronization or a fixed rate of chooser faves. For illustration, in artificial product, diverter  valves are constantly used to control the coterminous movement of multiple hydraulic cylinders or motors to ensure the stable operation of product lines. Diverter valves also play an important part in agrarian ministry, construction ministry, metallurgical ministry and other fields.

As an important control element in hydraulic systems, diverter valves achieve precise control and synchronization of selector pets through their unique working principles and structural design. Its wide operation in colorful fields provides strong support for the development of ultramodern assiduity.
