2 Spool Hydraulic Monoblock Loader Control Valve 11gpm With Floating Spool
This is a brand new high quality valve, it is designed for Front end Loaders, tractors or any application where you need to control one function or cylinders. It has a 'float' function on the second spool with detent, which means your Blade will 'skim' the ground . The other spool is a cylinder spool for an alternate function. It is a 'four' position lever, up, down, centre plus all the way down, is detent 'float'. The oil is open to tank in this position allowing your blade to rise & fall freely with the grounds contours.
Hydraulic Valve
The Hydraulic Valve actually, is a device that can change the opening degree of liquid(oil) flow path
They are manufactured in a variety of styles to function in different applications. Valves are used to manipulate the flow of hydraulic fluid within a hydraulic circuit and are activated either mechanically or electronically.
By Control Way
Manually Operation, Mechanical Drive, Hydraulic Transmission, pneumatic Transmission ,Solenoid Drive, Electric-Hydraulic Drive ,Solenoid Proportion Drive
Directional Control Valves
Directional control valves can control the start, stop and change in direction of flow of a pressure medium
Hydraulic directional control valves should be selected based upon both the size of the circuits and the components,
both upstream and downstream to the valve
A directional control valve comprises at least two spool (switching) positions and two working ports.
Flow ratings should be based upon the highest possible flow the valve will need to achieve.
