SECTIONAL VALVES


SECTIONAL VALVES
A valve that directs oil flow to hydraulic motors and cylinders is known as a sectional directional control valve. They're called switching valves a lot.

An essential part of every fluid power system are directional control valves. They are employed to regulate the hydraulic fluid's passage through a system. They are able to reroute the flow in various directions, for example, from the return line to the actuator or from the source to the actuator.
There are two primary factors to take into account when selecting a directional control valve: the quantity of fluid ports and the amount of directional states or positions the valve can accomplish.

Some characteristics of sectional directional control valves are as follows:
They are able to hold ten spools.
They can choose to mount primary relief valves, secondary relief valves,
check valves, and anti-capitation check valves
They have a compact construction design
They have low pressure drop
They are highly efficient
