SUMMARY:  Pressure valves: ZDB 10D.-2X

Add to Cart

Pressure valves of type ZDB10D and Z2DB10D are direct operated pressure relief valves in sandwich plate design.

The valves basically consist of housing (1) with seat (2) and control spool (3). The system pressure is set via the adjustment type (4).

The valves are closed in their rest position and protect a hydraulic system and its components against excessive pressures.

These valves respond quickly, noiselessly and in a virtually leakage-free manner. Thanks to the seat design, they are resistant against oil contamination. The integrated damping of the control spool (3) ensures extremely stable behavior and a low pressure increase with increasing flow.

In the state as delivered, the valves are set to the minimum possible pressure. The system pressure applied to channel P acts on the control spool (3). If the system pressure increases above the set value, the control spool (3) opens and the hydraulic fluid flows from channel P in channel T. This limits the system pressure to the set value.

For version “MP”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions)

Important information on hydraulic fluids!

For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The ignition temperature of the hydraulic fluid used must be [si]50 K[/si][imp]90 °F[/imp] higher than the maximum solenoid surface temperature.

Flame-resistant – containing water:

Maximum operating pressure [si]210 bar[si][imp]3050 psi[/imp], otherwise, increased cavitation erosion Life cycle as compared to operation with mineral oil HL, HLP 30 … 100 % Maximum hydraulic fluid temperature [si]60 °C[/si][imp]140 °F[/imp]

Bio-degradable and flame-resistant: If these hydraulic fluids are used, small amounts of dissolved zinc may get into the hydraulic system.

1) Not recommended for corrosion-protected version "J3" (contains zinc)

For applications outside these parameters, please consult us!
