★Functional Description
TY-DZ type pressure valves are pilot-operated sequence valves. They are used for pressure-related secondary circuit switching
switching. The sequence valve consists of a main valve (1) with a main spool insert (7), an optional check valve (3) with a pressure regulating assembly, and a pilot valve (2).
The sequence valve consists of a main valve (1) with main spool insert (7), a pressure regulating assembly, an optional check valve (3) and a pilot valve (2). Depending on the pilot return of the pilot control oil, these valves are functionally differentiated as follows.

(Control lines 4.1, 12 and 13 open: control lines 4.2, 14 and 15 blocked) The pressure in line A acts on the pilot spool (5) in the pilot valve (2) via the control line (4.1). At the same time, it is applied to the spring chamber of the main spool (7) through the liquid resistance (throttle orifice) (6). When this pressure exceeds the setting value of the spring (8), the pilot spool (5) moves against the spring (8). This pressure signal is obtained internally from port A via the control line (4.1). The oil from the spring chamber of the main spool (7) flows into channel B via the liquid resistance (9), the console shoulder (10) and the control lines (11) and (12). In this way, a pressure drop is generated at both ends of the main spool (7), ports A to B are opened and connected, and the pressure set by the spring (8) remains constant. Leakage oil from the pilot spool (5) is introduced internally via the oil circuit (13) into the oil channel B. An optional check valve (3) is installed for the free return of oil from ports B to A. DZ... DZ...-5X/... DZ...-5X/...X... Sequence valve type DZ...-5X/...X (control lines 4.2, 12 and 13 open; control lines 4.1, 14 and 15 blocked) The function of this valve is in principle the same as that of the DZ...-,-5X/...X sequence valve. In principle, the function of this valve is the same as that of the DZ...-,-5X/... type valve. The function of this valve is in principle the same as that of the DZ.

(control lines 4.1, 12 and 14 or 15 open; control lines 4.2 and 13 blocked) The function of this valve is in principle the same as that of the DZ...-5X/...Y...-5X/...Y... valve.

However, the function of the DZ... -5X/... type valve is the same in principle. - 5X/....... However, for DZ...-5X/... type valves, leakage from the pilot valve (5) must be discharged into the tank via the oil line (14) or (15) without pressure. Pilot control oil is introduced into channel B via line (12). DZ...-5X/... DZ...-5X/...XY... DZ...-5X/...XY... type sequence valve (control oil opens via lines 4.2, 14 or 15; control oil lines 4.1, 12 and 13 are blocked) Pressure at port X acts on the control piston (5) in the pilot valve (2) via the control oil line (4.2). At the same time, the pressure at port A acts on the spring chamber of the main spool (7) through the hydraulic resistance (6). When the pressure at port X exceeds the setting value of the spring (8), the control piston (5) overcomes the spring (8) and moves, allowing the oil to flow from the spring chamber of the main spool (7) into the spring chamber (17) of the pilot valve (2) via the liquid resistor (9) and the hole (16) and the pressure peak in the spring chamber of the main spool (7) decreases. As a result, the oil can flow with minimum pressure loss from port A to port B. The control oil in the spring chamber (17) should be discharged to the tank without pressure via line (14) or (15). An optional check valve (3) can be fitted for the free return of oil from port B to port A. The oil in the spring chamber (17) should be discharged without pressure into the tank via line (14) or (15).
