Classification and application of hydraulic cartridge valves

Hydraulic cartridge valve is a common hydraulic component, widely used in various hydraulic systems. It can control the flow and pressure of the fluid to achieve the stable operation of the system.

Hydraulic cartridge valves can be divided into various types according to different functions. The following will introduce the classification and application of hydraulic cartridge valves.

Directional control valve

The directional control valve is the most common hydraulic cartridge valve, which is mainly used to control the flow direction of the fluid, so that the actuators (such as hydraulic cylinders) in the hydraulic system can achieve positive and negative rotation and stop motion. Directional control valves usually consist of a set of spool and seat, and control the flow direction of liquid through different spool positions. Directional control valves are widely used in various hydraulic systems, such as construction machinery, agricultural machinery, ships, aircraft and automobiles.

Pressure control valve

The pressure control valve is mainly used to control the pressure of the hydraulic system. It can regulate the pressure in the system and keep the system stable under different working conditions. There are many types of pressure control valves, including relief valves, check valves, safety valves, etc. Pressure control valves are widely used in various hydraulic systems, such as hydraulic elevators, hydraulic door operators, hydraulic presses, etc.

Flow Control Valve

The flow control valve is mainly used to control the flow of liquid to realize the speed control and flow control of the hydraulic system. It usually consists of a spool and a valve seat, and controls the flow of liquid through different spool positions and orifice sizes. Flow control valves are widely used in various hydraulic systems, such as hydraulic cylinder control, hydraulic motor control, automatic production lines, etc.

Proportional control valve

Proportional control valve is a valve that realizes accurate flow control by adjusting the position of the control spool and the size of the orifice. It can control the flow and pressure of the fluid, and can accurately control the flow of the fluid to meet the complex control requirements. Proportional control valves are widely used in engineering machinery, automated production lines, metallurgical equipment, petrochemical equipment, textile machinery and other fields.
