Hydraulic Directional Valve Function

Elephant Fluid Power has attracted a large number of customers with its careful and rigorous production and excellent after-sales service, and its sales network is very developed, with customers in more than 30 countries. Elephant Fluid Power also has a lot of experience in the production of hydraulic directional valves, so what is the hydraulic directional valve used for? Let's find out together.

Hydraulic steering valve is a valve that controls the direction of hydraulic oil flow in the hydraulic system, also known as the reversing element of the hydraulic system, and the flow valve and pressure valve control valve in different directions directly control the load.

Introduction to directional control valve of hydraulic system: Directional control valve only needs a small force to toggle the handle of the directional valve to control it very much

Heavy loads. For example, excavators, loaders, truck cranes, etc., are through the joystick to control each group of actions, this type of machinery is characterized by complex working conditions, requiring delicate operation, requiring compound actions, some old drivers with this type of machinery to complete a lot of incredible operations.

Classification of directional control valves for hydraulic systems:

According to the function: directional control valves include check valves and directional valves. Check valves and directional valves come in many different forms. Check valves include ordinary check valves and hydraulic check valves, hydraulic check valves can be used as filling valves, and two hydraulic check valves can be combined into hydraulic locks.

According to the control mode: manual directional valve, hydraulic directional valve, electromagnetic directional valve, electro-hydraulic directional valve, etc. Multiple directional valves can be combined into multi-way valves that can manipulate multiple sets of actions.

Working principle of hydraulic system directional control valve:

The directional valve is made axial movement in the valve body through the spool, so that the corresponding oil circuit is connected or disconnected. There are multiple sinking grooves in the valve body, which are connected to the outside through the orifice, and there are multiple steps on the valve core. The directional valve is switched by changing the connection between the steps on the spool and the sinking groove on the valve body.

In addition, there is a "function" in the directional control valve, which refers to the connected state of the directional valve, and when designing the hydraulic system, the selection of the neutral function of the directional valve is very important, which has a direct impact on the hydraulic system.
