rexroth type hydraulic pilot operated sequence valve for helmet manufacturing machine
Model No.: DZ10
Product Description rexroth type hydraulic pilot operated sequence valve for helmet manufacturing machine
|The valve utilized line pressure for controlling the Other Hydraulic parts acting in sequence and to realize automatic controlled in Hydraulic System. It can act as an unloader or a back pressure valve.|
|Symbol of diagram|
The leakage oil of the controlling piston will flow to B cavity with inner passage(10).
If the oil flows from B cavity to A cavity, please elect the structure with inner check valve. Type DZ…30/21X The principle of operation is the same for the type DZ…-30/21. Only the input mode of controlling oil is different. The controlling oil of type DZ…-30/21X flows through passage(2)from outside. Type DZ…-30/21Y The principle of operation is the same for DZ…-30/21. Only the drain mode of the controlling piston with leakage is different.
The leakage oil of the controlling piston for the type DZ…-30/21Y must exhaust from passage(10)or (11) to reservoir under no back pressure condition.
The controlling oil goes through passage(9)to B cavity. Type DZ…-30/21XY The pressure oil of X cavity goes through passage(2),damper(1)which acting on the controlling piston(3)of the pilot valve(4). At the same time, the pressure of A cavity goes through the damper(5)which acting on the top cavity of the main spool(6). When the pressure of X cavity exceeds the rated valve of the spring(7), the controlling piston will move to the spring(7). Because of the piston(3)moving, the oil of top cavity main spool through(8)and hole(15)to the spring cavity(12)of the pilot valve(4). Thus the pressure oil flows from A cavity to B cavity under hardly any pressure loss condition. In order to attain the goal of unloading.
The oil of the spring cavity(12)exhausts from passage(10)or(11)to reservoir under no back pressure condition. If the pressure oil flows from B to A, please elect the structure with a check valve.
Structure with check valve Structure without check valve. Characteristic curve (test condition: ν=41mm2/S,t=50°C) Outer dimension These curve are available to control oil with no back pressure for outer return conditions. External and connecting dimensions 1.Adjusting scale cover 2.Adjusting mode 1 3.Adjusting mode 2 4.Adjusting mode 3 5.Position pin 6.Connection port Y1 ( as back pressure valve and sequence valve puter drain port for controlling oil ) 7.Name plate 8.Connection port Y ( as unloader and sequence valve spring cavity outer drain port for controlling oil )
