Vickers PA5DG4S4LW-0133C-H-60-S471 Direction Hydraulic Valve Stainless Steel

Product Description:

Directional valves are mainly used to control the flow direction of fluid in hydraulic systems to meet the requirements of starting, stopping and moving direction of actuators. Directional valves can be divided into two categories: one-way valves and reversing valves.

One-way valves
The one-way valve, also known as a check valve, is characterized by allowing fluid to flow in only one direction and being cut off in the reverse direction. According to the structure of the valve core, one-way valves can be divided into ball valve type and cone valve type. The ball valve type has a simple structure but poor sealing performance and is suitable for low-pressure occasions; the cone valve type has good sealing performance and is widely used. The main function of the spring in the one-way valve is to help the valve close quickly when there is no oil flow, but at the same time it will increase the resistance when opening and cause pressure loss. In some occasions, when the one-way valve is required to allow the oil flow to pass in the reverse direction, a hydraulically controlled one-way valve can be used, which relies on controlling the fluid pressure to make the one-way valve flow in the reverse direction.

Reversing valves
The function of the reversing valve is to connect or close the oil circuit or change the flow direction of the oil to the actuator through the relative movement of the valve core and the valve body to achieve the start, stop or change the movement direction of the actuator. Directional valves are divided into slide valve type and rotary valve type according to their structure; they are divided into two-position, three-position and multi-position according to the number of working positions of the valve core; they are divided into two-way, three-way, four-way and five-way according to the number of inlet and outlet channels; they are divided into manual, motorized, electric, hydraulic and electro-hydraulic according to the operation and control methods; they are divided into pipe type, plate type and flange type according to the installation method.

Application scenarios
Directional valves are widely used in various hydraulic systems, especially in situations where it is necessary to control the unidirectional flow of fluid or to frequently change the flow direction of fluid. For example, in engineering machinery, directional valves are used to control the extension and contraction of hydraulic cylinders and the power assistance of steering mechanisms. In addition, directional valves are also commonly used in hydraulic support equipment, such as hydraulic support equipment for coal mine machinery, to achieve functions such as locking and supporting hydraulic cylinders by controlling fluid pressure.
