Hydraulic Valves
Hydraulic control distributors: how to choose and buy?
A hydraulic distributor is a special device that controls the flow of working fluid: it can change direction and start or stop the flow to control hydraulic cylinders or motors. The principle of operation is simple: channels are switched using moving elements.
Hydraulic distributors are essential for the smooth operation of specialized transport systems used in construction, agriculture, and manufacturing.
By design, hydraulic distributors can be:
- Spool valves: have a spool that controls the working fluid;
- Poppet valves: here the fluid flow is controlled by a valve;
- Rotary valves: flow control is achieved by rotating the rotor.
By control type, a hydraulic distributor can be: manual (controlled by a lever or handle), electromagnetic (an electromagnet initiates valve movement), hydraulic (controlled by working-fluid pressure), or pneumatic (control element movement is achieved by air-flow pressure).
A hydraulic distributor has the following technical characteristics:
- Working pressure: indicates the maximum power of the device and compatibility to work in a specific hydraulic system of special equipment;
- Number of sections: indicates the ability to control a certain number of actuators;
- Control types: manual, electromagnetic, and hydraulic;
- Compatibility with hydraulic systems: determined depending on the type of working fluid, pressure capabilities, and operating conditions;
- Housing material: cast iron, aluminum, or steel. It determines the structure's strength, weight, pressure capacity, and usage conditions.
When choosing a hydraulic distributor, pay attention to the technical characteristics, namely: whether the hydraulic system is compatible with other components of the structure. Choose a convenient mounting method and check the quality of the materials and the reliability of the fasteners.
