Brake Valve, service brake - 01.35.152 TRUCKTEC AUTOMOTIVE

As the title implies, the TRUCKTEC AUTOMOTIVE brand Brake Valve, service brake to ensure the smooth operation of hydraulic motors (hydraulic motor or hydraulic cylinder), and also performs the function of a hydraulic lock. Under the action of passing loads, the motion vector of which coincides with the direction of movement of the hydraulic cylinder or hydraulic motor, jerks and oscillations occur, which leads to instability of the hydraulic system. Brake valves help to achieve the necessary smoothness in the operation of hydraulic motors.

The operation of a service brake valve

A spool is installed in the valve body, which is acted upon by a spring; a screw regulates the preload force. Under the action of the spring force, the spool moves to the right (according to the scheme), the belt on the spool blocks the channel for the movement of fluid. Pressure from the control line acts on the opposite end of the spool, under the influence of this pressure the spool moves to the left (according to the scheme), tearing off the channel for the fluid flow. In the absence of pressure in the piston cavity, the spool of the brake valve will block the flow area under the action of the spring, the liquid will not be able to flow out of the rod cavity of the cylinder, the rod will remain in place.
