ZDR...D type pressure reducing valve is a stacked pressure reducing valve. It is designed as a three-way valve. It has secondary oil circuit pressure protection. It is used for pressure reduction in hydraulic systems.
The valve is mainly composed of a valve body (1), a control spool (2), one or two pressure springs (3), a pressure regulating mechanism (4) and optional
The one-way valve composition. The pressure valve of the secondary oil circuit is adjusted to the original position through the pressure regulating mechanism (4), and the oil in the open state freely flows from the P channel to P1 (DP type) or from A to A1 (DA type).
At the same time, the pressure oil in the P1 channel acts on the end face of the spool (6) through the control channel (5). If the pressure oil in the P1 channel is greater than the set value of the spring (3), the control spool (2) will move to the set value. value position, and will maintain this set value in the P1 channel pressure as a constant value.
The control signal oil is input through the internal (5) channel of the spool (6). If the load is acted by an external force, causing the pressure of P1 to continue to rise, the spool (2) is pushed to the side of the spring (3), and the oil returns to the oil tank from the P1 channel through the control side (7), keeping the pressure no longer rising, and leakage The oil leaks out through the T (Y) channel through the spring cavity (8). The "DA" type valve can be equipped with an optional check valve to allow oil return from A1 to A freely.
At port (9) of the valve, a pressure gauge can be installed to read the pressure of the secondary oil circuit.
