What is a float section in a hydraulic directional control valve?

A float section is a function in a hydraulic control valve that allows the controlled elements (e.g., cylinders) to move freely in both directions without the need to supply pressure from the hydraulic system. In practice, this means that hydraulic oil flows freely between the cylinder and the tank, which allows, for example, working tools to adapt to uneven terrain. Thanks to this function: Working elements of the machine can rise or fall under their own weight or external forces. There is no excessive load on the hydraulic system, which increases the durability of the entire system. This solution is often used in agricultural, construction, and forestry machinery, where operational flexibility plays a key role.

What distinguishes directional control valves with a float section? 

Float section in a hydraulic control valve is a special function that enables free movement of controlled elements, such as machine arms, without the need for constant hydraulic pressure supply. This allows cylinders to move naturally, adapting to terrain conditions or loads, which is particularly useful in machines such as excavators, loaders, or plows.

Why is it worth choosing directional control valves with a float section?

Directional control valves with a float section can be used in machines requiring smooth operation of arms or other moving parts. The float section function minimizes the risk of damage to cylinders and mechanisms as a result of excessive loads. These valves provide full control over the flow of hydraulic fluid, regardless of the number of sections. The products available in this category are characterized by solid construction and high-quality workmanship.
