What is a Dual Coil Solenoid Valve

Solenoid valves are indispensable components in the hydraulic and pneumatic systems of construction machinery, used to control the flow of fluids. Among them, dual coil solenoid valves are a special type of solenoid valves that offer unique advantages in certain applications.

Basic Principles of Humbucking Solenoid Valves

A humbucking solenoid valve contains two coils, often referred to as an opening coil and a closing coil. These two coils are located inside thediesel solenoid valvevvv and interact with the body and valve.

The operating principle of a humbucker solenoid valve is based on electromagnetic excitation. When an electric current passes through one of the coils (usually the opening coil), it generates a magnetic field which causes the valve to move, opening or closing the valve, depending on the design. When it is necessary to change the state of the valve, the current is switched to the other coil (usually the closing coil) so that the direction and strength of the magnetic field changes, resulting in a change in the state of the valve.

Highly Reliable Operation

Dual coil solenoid valves are typically more reliable than single coil solenoid valves because they do not rely on springs or other mechanical parts for operation. This design reduces failures due to worn parts and allows the solenoid to respond more quickly when needed to match other diesel engine parts.

Applications for multifunctional systems

Construction machinery often requires multiple functions, and dual-coil solenoid valves are ideal for responding to this need. They can be used to switch between different hydraulic circuits to achieve multi-functional operations such as lifting, lowering, tilting and rotating. This versatility makes dual-coil solenoid valves ideal for use in a wide range of construction equipment, as well as other components such as starter motor and alternators.

Energy saving and precise control

Dual-coil solenoid valves provide precise control of fluid flow, thereby improving the energy efficiency of the system. They can be switched quickly, reducing wasted fluid while lowering the system's energy consumption, which is especially important for construction machinery that needs to run for long periods of time.

Installation and maintenance

Dual coil solenoid valves are often relatively simple to install and maintain. They are designed so that coil replacement or maintenance can be done quickly, reducing downtime and repair costs.

Humbucking solenoid valves are an important component in the hydraulic and pneumatic systems of construction machinery, offering the advantages of highly reliable operation, versatility, energy savings and precise control. Understanding their operating principles and applications will help to better understand and utilize this technology to improve the performance and efficiency of construction machinery. When selecting a solenoid valve, a dual coil solenoid valve may be an ideal choice, taking into account the specific needs of the application.
