Hydraulic Control Valve

Hydraulic Directional Valve Manufacturer in China

What is a Hydraulic Directional Valve?

The directional valve is responsible for regulating the fluid flow direction. It functions by starting, changing, or stopping the fluid flow. These types of valves are also considered as controllers. They regulate the flow of pressurized fluid. So, the hydraulic system’s cylinders or actuators will fully function. It also allows the fluid to flow in a certain direction. These valves are specifically designed to ensure efficient, precise, effective, and smooth fluid control. Thus, allowing different machines and equipment to accurately deliver their tasks.

Directional valve allows seamless operation of construction equipment to lift heavy loads. The smooth execution of complicated aerospace system operations is possible through hydraulic direction valves. Using a directional valve for your hydraulic system applications can increase safety. It also increases your system’s performance level. Hydraulic directional valves also significantly reduce energy consumption.

Brief History

The technological development for directional valve has historical roots in ancient civilizations. It is the time when water power is utilized for operating watermills.

During 20th century, modern directional valves were developed through the advancement of control systems and hydraulic technology.

Industries today such as manufacturing, agriculture, and more operate through hydraulic systems. This leads to the increasing need of efficient flow control. To address the needs, highly precise DCVs today are produced.

Applications

Target Hydraulics offers an efficient hydraulic directional control valve that is used across different industries including:

Industrial Automation

Automated equipment integrated with a hydraulic directional valve is guaranteed to have controlled movement. This equipment include conveyor belt, robotic arm, and more. Thus, allowing trouble-free assembly processes.

Construction

Directional valves are crucial for operating heavy machines in the construction industry like loaders, excavators, bulldozers, and more. They provide precise controls for different functions such as lifting or digging.

Agriculture

Agricultural equipment commonly have attachment. These attachment moves when the equipment is operating. To control the movement, a hydraulic directional valve is needed.  This allows precise farming operations.

Different Types of Hydraulic Directional Valve

Spool

As its name implies, a cylindrical spool is integrated in the valve. This spool moves within its body. Based on its position, you can identify the path of fluid flow. Thus, determining the fluid flow direction. Its configurations include:

  • 2-way – Allow or block the fluid flow in one direction, without affection the flow in the opposite direction
  • 3-way – Redirecting the fluid flow from one source into two distinct pathways
  • 4-way – Selectively route the fluid flow to the desired cylinder or actuator
  • 5-way – It has the same functionality with 4-way valve, however, it has an additional port for exhausting pressure
Poppet
Poppet

These types of DCVs regulates the flow of fluid using its cone-shape poppet feature. It can provide less leakage. Thus, making it ideal for applications with high pressure or critical systems. Poppet valves have two configurations including:

  • Direct-acting – actuated using only mechanical force. Does not require separate pilot system
  • Pilot-operated – actuated using pilot pressure. Thus, offering better versatility and control ability
Rotary
Rotary

It controls the flow of fluid through rotary motion. The rotary motion is caused by a rotating cylinder. There are two types of rotary valves including:

  • Sliding cylinder – the sliding cylinder feature of this valve is responsible for regulating the direction of fluid flow
  • Rotary spool – the rotary spool feature of this valve is specifically designed to control the path of fluid flow

Working Principle

Actuation Methods

Our hydraulic directional valve is designed with various actuation method. It includes:

Manual – valves are actuatable using either a lever or a knob. Thus, enabling simple and direct position control.

Solenoid – solenoid valves utilize an electrical signal as a means of actuation. Their ability to be remote controlled makes it ideal for automated system applications.

Hydraulic – a hydraulic pressure is needed to change the position of the valve. This actuation offers efficiency and precision.

Symbols/Positions

Hydraulic directional valve uses symbols. These symbols help to convey information about the valve position. Its position includes:

  • Regenerative Center
  • Open Center
  • Closed Center
  • Float Center
  • Tandem Center
