Proportional Pressure Sequence Valve EPDZA 06
The proportional pressure sequence valve EPDZA allows oil coming from channel P to flow from a defined, proportionally adjustable opening pressure to channel A.
If the pressure in channel P drops under the setpoint value, the valve closes with low hysteresis.
In contrast to pressure relief valves, with EPDZA the actual opening pressure in channel P remains constant, regardless of pressure variations in channel A (requirement P < A).
The EPDZA consists of a remote-controlled mechanical pressure relief valve, which is piloted by a proportional pilot valve. The spring chamber of the pilot stage of the mechanical valve is relieved separately via channel T.
If the pressure fluctuations in the T-channel are negligible, the control oil of the proportional pressure relief valve can be channelled to T (plug 1, see icon). Otherwise, it must drain to channel B (plug 2). The valve has a mechanical maximum pressure setting. Below this setting, the valve works proportionally.
Fields of application:
- The EPDZA is used for a more precise adjustment of consumer or system pressures, as it is independent of pressure fluctuations in the flowing oil.
- For clamping and braking functions, to ensure that a certain pressure is present before the oil can flow to further consumers.
