A hydraulic valve is an important element of the hydraulic system, designed to regulate pressure and other parameters of the working fluid. The principle of operation is based on changing the flow area. For this purpose, the design provides a shut-off and control element, with which you can change the pressure and direction of the working fluid.
Areas of use
Hydraulic valves are used in different types of hydraulic equipment:
- in hydraulic cylinders used in special equipment — excavators, loaders, earth-moving machines;
- in auto service equipment — transmission racks, jacks, cranes;
- in drilling rigs.
Vehicles typically use solenoid-controlled hydraulic valves in the engine power supply, windshield wiper systems, and preheaters.
Types of hydraulic valves
According to their purpose, these devices are divided into regulating and guiding.
Regulating (throttle)
Regulating valves include hydraulic valves — safety, overflow, pressure reducing, differential pressure, pressure ratio. A common option is hydraulic safety valves of direct and indirect action, used in hydraulic systems of presses, metalworking machines and other production equipment, and lifting and transport equipment.
Guides
Guides include hydraulic check valves that allow the working fluid to flow in only one direction and prevent its unauthorized movement in the opposite direction. Also included in this group are sequence and time delay devices.
