DESCRIPTION OF FUNCTION, SECTION
They comprise of the following:
• housing (1)
• adjustment spring (2)
• adjustment mechanism (3)
• poppet (4)
• poppet seat (5)
• plug (6)
• cartridge body (8).
Pressure relief valves are normally closed. Pressure at the port
(7) acts upon the exposed surface area of the poppet (4). If the
pressure at the port (7) exceeds the value set on the adjustment
spring (2), the poppet (4) opens. Fluid flows from the spring-
loaded side of the poppet (4) into tank.
These valves could be used also as main stage valves!
Pressure relief valves type N-ZDBDHP06 are direct operated
poppet type valves in sandwich plate design. They limit maxi-
mum pressure in a hydraulic system.
