Model Code: DZT-XA2-10/160
Pressure relief valves of type DBT are remote control valves with seat design and are used for limiting a system pressure. The setting is completed manually, via the adjustment type (4). The valves basically consist of the housing (1), the valve poppet (2) and the related valve seat (3).

In the unloaded position, the valve poppet (2) pushes onto the valve seat (3) and blocks the connection between P and T connection. If the hydraulic force equals the force set at the adjustment type (4), the valve controls the set pressure. By lifting off the valve poppet (2) from the valve seat (3), the excessive hydraulic fluid may flow off from P to T.
