There are a variety of pressure reducing valves that are designed to meet the highest safety requirements of braking systems
Depending on the application, our product range ranges from single function components (for service brakes, emergency brakes, and accumulator charging valves) up to fully customized compact solutions that can be fully customized in order to meet the specific requirements of the specific application.
A brake valve performs the same function as a counterbalance valve, but it is designed with a number of advantages in order to overcome some of its disadvantages. This point will be illustrated with the help of an example. In a motor circuit, let us assume the use of a direct-operated counterbalance valve. There are times when the motor load can overrun, and in this case, the motor needs to be braked in order to prevent damage. The pressure across this valve is set to 350 psi, and the pressure drop across the motor to supply the required torque is also 350 psi. It is necessary for the pump to develop a pressure of 350 + 350 = 700 psi.
There are three types of Eaton brake valves available
power, manual and hybrid styles, with single or double spools. In a double-spool brake valve, there are two identical valves mounted together in the same casting, which can be used as a pair for brake-assisted turning or individually for brake-assisted turning if desired. Two types of Eaton brake valves are available: the power brake valve and the manual backup brake valve. A power mode valve operates in the same way as a pressure-reducing valve when it is in power mode. To increase the safety of the system, the manual mode of the valve operates as a two-stage pump.
