ZDBDP
DESCRIPTION OF FUNCTION
16
They consist of
• Housing (1)
• Adjustment spring (2)
• Adjustment mechanism (3)
• Ball (4)
• Dampening sleeve (5)
Pressure relief valves are normally closed. Pressure at
the port (6) acts upon the exposed surface area of the ball
(4). If the pressure at the port (6) exceeds the value set on
adjustment spring (2), then the ball (4) opens. Fluid flows
from the spring-loaded side of the ball (4) into tank.
These valves should be used only as pilot valves !
Pressure relief valves type ZDBDP06 are direct operated
pressure relief valves in sandwich plate design. They are
used to limit the maximum pressure in a hydraulic system.
