Function and configuration
DZ10DP sequence valve is direct-acting valve. It is for sequence switching related with secondary loop and pressure. Set sequence pressure through adjusting elements (1).
Compression spring (2) holds valve element (3) in initial position and the valve is closed. Pressure of Port A enters the valve element end through control route (4), of which the produced force acting on the valve element (3) on the opposite side of spring (2).
When the pressure reaches the set valve of spring (2), valve element (3) is pushed to connect port A and B; systems connected with oil port B is connected in sequence while the pressure of port A will not drop; control signal is acquired from port A via control route (4) or acquired from the outside via port X.
According to the valve purpose, leaked oil can return from the outside of port Y or the inside of port B.
