Dual winch brake valve is a kind of hydraulic brake? What's the principle of hydraulic brake?

Hydraulic brakes mainly generate braking force through hydraulic pressure, thereby achieving braking. Its main structure includes brake discs, brake cylinders, pipelines connecting brake discs to brake cylinders, and control valves. When the brake handle is operated, the oil in the hydraulic system is pressed into the brake cylinder, causing the piston inside the cylinder to move, thereby pushing the brake disc to generate braking force. Hydraulic brakes have the characteristics of high braking force and smooth operation, and are suitable for large lifting equipment.

The brakes of lifting equipment mainly generate braking force through friction or hydraulic pressure, thereby achieving the braking and protection effects of lifting equipment. According to different principles and structures, suitable brakes can be selected to meet the specific working requirements of lifting equipment. 

What is the function of the brake valve?

The brake valve is used to act as a follower and ensure a strong enough pedal feel, that is, when the input pressure is certain, its output pressure has a certain increasing function relationship with the input control signal - the pedal stroke and the pedal. The change of its output pressure should be subtle enough within a certain range.
