Hydraulic Valves

Hydraulic control valves - an important element of special equipment: how to choose and buy?

A hydraulic control valve is a special device that controls the flow of working fluid: it can change direction, start or stop the flow to control hydraulic cylinders or hydraulic motors. The principle of operation is simple: channels are switched using moving elements. 

Hydraulic control valves are necessary for the comfortable operation of special transport systems used in construction, agriculture, and manufacturing.

By design, hydraulic control valves are: 

• 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 control valve can be: manual (controlled by a lever or handle), electromagnetic (valve movement is initiated by an electromagnet), hydraulic (using working fluid pressure), pneumatic (control element movement is achieved by air flow pressure).

A hydraulic control valve 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: this can be cast iron, aluminum, or steel - determines the strength and weight of the structure, pressure capabilities, and usage conditions. 

When choosing a hydraulic control valve, 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 also check the quality of materials and the reliability of fasteners.
