When is a Pilot Operated Solenoid Valve Required

In the operation of construction machinery, fluid control of hydraulic and pneumatic systems plays a vital role. And in these complex control systems, solenoid valves play a key role. Among them, driven solenoid valves, as a special type of solenoid valves, show their unique value in some cases. In this article, we'll take a closer look at when actuated solenoid valves are needed to meet specific needs in construction machinery.

High pressure and high flow requirements

In some construction machinery applications, the flow and pressure requirements for liquids or gases can be quite high. Typical solenoid valves may not be up to the task, and this is where actuated solenoid valves become important to help other components, such as starter motor and alternators, work better together. For example, large excavators require high-flow hydraulics for smooth operation of heavy loads, which requires the use of actuated solenoid valves that can withstand higher flows and pressures.

Complex operation and precise control

Some construction machinery needs to realize the precise control of multiple steps, positions or parameters. This may involve different flows, pressures and changes in direction. Actuated solenoid valves are particularly useful in such cases because they enable more precise control of fluid flow for complex operations. For example, the lifting and lowering of a construction crane requires precise control, which necessitates the use of actuated solenoid valves for delicate operations.

High durability and reliability needs

Some construction machinery requires long hours of continuous operation, and the equipment is required to have a high degree of durability and reliability. Driven diesel solenoid valve usually have a stronger structure and design, and can maintain stability under continuous high-intensity work. For example, concrete pump trucks need to deliver concrete continuously, so they need to use actuated solenoid valves that can withstand high-frequency operation.

Harsh environment and high temperature requirements

The diesel engine parts in construction machinery usually need to operate in a variety of harsh environments, such as high temperature, low temperature, humidity, and so on. Driven solenoid valves usually have better sealing and resistance, and can work properly in harsh environments. For example, agricultural machinery works in outdoor environments and requires solenoid valves that can cope with various weather conditions.

Versatility and adaptability

Some construction machinery needs to operate in a variety of applications, such as the need to handle different work tasks or work media. Actuated solenoid valves offer greater adaptability and versatility to meet different fluid control needs. For example, a city sanitation vehicle used for cleaning and hygiene may need to handle different types of fluids, which requires the use of actuated solenoid valves that can be adapted to different media.

The application of actuated solenoid valves in construction machinery depends on specific needs and working conditions. They show their unique value when faced with challenges such as high pressure, high flow, complex operations, and harsh environments. Therefore, when selecting solenoid valves, it is a crucial decision to determine whether a driven solenoid valve is required based on the actual application requirements.
