What is a 4/3 Hydraulic Valve? How It Works

4/3 hydraulic valves play an important role in optimizing the performance and precision of hydraulic systems, helping to improve the operation of equipment and machinery in various industries. So what is a 4/3 hydraulic valve? How does it work? Let's learn more about this type of valve with Truong Linh Parts.

1.What is a 4/3 Hydraulic Valve?

4/3 hydraulic valve is a type of hydraulic valve widely used in industrial hydraulic systems to control the pressure, flow and direction of movement of hydraulic fluid. The number "4" in the name refers to the four connection ports and the number "3" refers to the three working positions of the valve.

This valve usually includes four holes: three holes are responsible for controlling the fluid flow and one hole is used as a discharge or balance hole. The operating mechanism of the 4/3 valve allows controlling the direction of fluid flow in the hydraulic system.

Typically made from high-pressure materials such as stainless steel or aluminum alloy, 4/3 valves have a reliable and durable design. Flexibility in fluid control, especially in applications requiring direction switching or position control of hydraulic cylinders and motors, is this valve's strong point. 4/3 hydraulic valves play an important role in optimizing the performance and precision of hydraulic systems, helping to improve the operation of equipment and machinery in various industries.

2. Structure and working principle of 4/3 hydraulic valve

2.1.Basic Structure of 4/3 Hydraulic Valve:

1.Valve Body: The valve body is the main frame of the 4/3 hydraulic valve and contains all internal components. Valve bodies are often made of high-pressure materials such as steel or aluminum to ensure durability and safety.

2. Connection Ports: 4/3 hydraulic valve has four ports connecting to the hydraulic system:

Four Connection Ports: The 4/3 hydraulic valve has four ports that connect to the hydraulic system. These ports are usually numbered from P, A, B and T.

P: Pressure Port - Where hydraulic fluid pressure is supplied.

A and B: Two working ports (Actuator) - Where pressure is transferred to control the direction of movement of actuators, such as hydraulic cylinders.

T: Return port (Tank) - Hydraulic fluid returns to the tank.

3.Working Position: 4/3 hydraulic valve has three different positions to control the fluid flow and direction of movement:

Neutral Position: When the valve is in this position, there is no fluid flow and pressure is not transferred to the actuator.

Working Position 1: Pressure is transferred from port P to port A, pushing the actuator to move in direction 1.

Working Position 2: Pressure is transferred from port P to port B, pushing the actuator to move in direction 2.
