A motor balancing valve is a kind of external control and hydraulic motor supporting the use of internal leakage one-way sequence valve, by a check valve and a sequence valve and together in the composition of the hydraulic circuit, can block hydraulic motor oil in the oil circuit, so that the hydraulic motor will not be due to the load of self-weight down to ensure that the load is in a certain position in order to ensure that the load is reliably stopped at a certain position, at this time, the role of the blocking.
When the hydraulic motor needs to move, the other oil is through the liquid, and at the same time through the internal oil circuit of the balance valve to control the sequence valve to open the circuit to achieve its movement, because the sequence valve itself in the working circuit to establish a certain back pressure, you can control the balance of the movement of the load when it falls to prevent over-speed sliding of the motor due to the weight of the hydraulic motor to produce shocks and vibration. This valve is widely used in hydraulic circuits with high speed and heavy load and certain requirements for speed stability.
