This model shows an example of how a brake valve can be used in a hydrostatic transmission. The brake valve closes when the pressure drops on its pilot port. This allows pressure to build up on the motor outlet, which causes it to slow down faster.

Fig. 1 shows how the motor initially accelerates and then stops. Fig. 2 shows how the brake valve closes when the motor is brought to a halt. Fgi. 3 shows how the pressure at the motor outlet is kept high as long as the motor is rotating and the brake valve is closed.
