What Does a Hydraulic Directional Valve Do

Hydraulic directional valves are directional control valves with more than two flow forms and more than two oil ports. It is a valve that realizes the communication, cutting and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. The valve is controlled by the direction of the relative movement of the spool and the valve body. There are two types: rotary valve type and spool valve type. According to the number of working positions that the valve core stays in the valve body, it is divided into two positions, three places, etc.; According to the number of oil circuits connected to the valve body, it is divided into two-way, three-way, four-way and six-way; The operation of the valve core movement includes manual, motorized, electric, hydraulic, electro-hydraulic and other types. The function of the hydraulic directional valve is to control the start, stop and movement direction of the actuator.


  1. The directional valve is a directional control valve with more than two flow forms and more than two oil ports.

  2. Adjust the flow direction of hydraulic oil and adjust the flow to the working mechanism.

  3. It is a valve for communication, cutting and reversing of hydraulic oil flow, as well as pressure relief and sequential action control. The directional control valve is by the relative movement of the spool and the valve body. It can be divided into rotary valve type and spool valve type.

  4. What oil circuit the oil port is connected to need to be determined according to the actual situation, such as feedback oil circuit, cylinder port, motor leaching oil port, and other actuators, control oil circuit, logic oil circuit and so on.

  5. The way of valve core movement is manual, motorized, electric, hydraulic, electro-hydraulic, etc.


Directional control valves are used to control the direction and on/off of fluid flow in hydraulic systems. It is divided into two categories: check valves and directional valves. Check valves are mainly used to control the one-way flow of oil; Directional valves are mainly used to change the flow direction of oil or to open or cut off the oil circuit.

In petroleum, chemical, mining and metallurgical industries, six-way directional valve is an important fluid reversing equipment, the valve is installed in the thin oil lubrication system to transport lubricating oil pipeline, by changing the relative position of the sealing assembly in the valve body, so that the valve body channels are connected or disconnected, so as to control the fluid reversing and start and stop.


In recent years, the demand for hydraulic directional valves in major related industries has become more and more large, and the precision requirements for their production and manufacturing have become higher and higher. Since its establishment, Elephant Fluid Power has been adhering to the business philosophy of quality first, customer first, spending a lot of time and money on the production technology team, not only introducing German advanced equipment, but also recruiting a large number of talents, and striving to produce the best quality products, it is so, Elephant Fluid Power has a very large number of repeat customers, choose Elephant Fluid Power, you will have the best quality products and services at the same time.
