Hydraulic Solenoid Valve - Structure and Operating Principle

What is a hydraulic solenoid valve? What is its structure and operating principle? Join Truong Linh Parts to learn about hydraulic solenoid valves and the structure and operating principles of this device along with applications in the article below.

1.Hydraulic solenoid valve

Hydraulic solenoid valves are electromagnetically controlled directional valves used in hydraulic systems to open, close or change the flow direction of fluid. The valve operates using a solenoid, which is a coil of electrical wire wrapped around a ferromagnetic core at its center. Valves consist of various chambers also known as ports. The solenoid is used to slide the spool in the valve, opening or closing the ports. The spool is a cylindrical part that serves the function of a valve by blocking or allowing the flow of fluid through these ports, depending on its location.

Hydraulic solenoid valves are widely used in industries such as manufacturing, aerospace, construction and many other industries that require hydraulic systems.

2. Structure and operating principle of hydraulic solenoid valve

2.1. Structure of hydraulic solenoid valve

Hydraulic solenoid valves are composed of the following main components:

1. Valve housing: Usually a block of metal or alloy that can withstand high pressure and capacity.

2.Valve Body: The valve body is the main part of the valve, usually made of materials that can withstand pressure and hydraulic fluid such as stainless steel or alloy. The valve body has holes or ports that allow fluid to flow in and out of the valve.

3. Solenoid coil: An important part of the solenoid valve, consisting of an electrical coil made from copper or aluminum wire. The coil generates a magnetic field for the device and is sealed by an insulating material to prevent electric shock and corrosion.
