►Product parameters

02P is a 6-way overflow valve.

The overflow valve can adjust the pressure, which is equivalent to a pressure regulating valve. It mainly plays the role of voltage stabilization, constant pressure relief system unloading and safety protection in hydraulic equipment.

Function, Section

The pressure valves of the ZDB and Z2DB types are pilot operated relief valves and are of a stacked disc design.
These valves are used to limit the pressure within the hydraulic system.
Their basic composition is the shell (7) and one or two relief valve spools.
The system pressure is set by the regulating element (4).

When the eye is resting, the valve is closed. The pressure at port A acts on the spool valve (1). At the same time, pressure acts on the spring-loaded side of the spool valve (1) via the orifice (2) and on the pilot seat (6) via the orifice (3). If the pressure at port A rises and exceeds the value set on the spring (5), the pilot seat (6) opens. This allows fluid to flow from the spring-loaded side of the spool valve (1) to port T through the orifice (3) and passage (8). The resulting pressure drop moves the spool valve (1), opening the A to T connection, while maintaining the pressure set at the spring (5).
The pilot oil is returned externally from the two spring chambers via port T.

The pressure valves of the ZDB and Z2DB types are pilot-operated residual valves with a stacked disc design. These valves are used to limit system pressure. These valves mainly consist of a housing (7) and one or two pressure valve spools. System pressure can be set using adjustment type (4). Closed at initial position time. The pressure at channel A acts on the spool (1). At the same time, this pressure is also applied to the spring-loaded side of the spool (1) via the nozzle (2). And applied to the pilot spool (6) through the orifice (3). If the pressure at channel A exceeds the value set on the spring (5), the pilot spool (6) opens. Hydraulic oil flows into passage T (TA) from the spring loaded side of the spool (1), orifice (3) and passage (8). The resulting pressure drop moves the spool (1), opening the A to T (TA) connection. The pressure set on the spring (5) is set in channel A.
