Description Size 6 Component series 1X Maximum operating pressure 350 bar Maximum flow 3 l/min Features Direct operated valves for limiting a system pressure Use as pilot control valve For subplate mounting and control panel design Product description 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. With completely unloaded spring (5), the minimum pressure of 3 bar (spring preload force) will settle. These valves are basically used as pilot control valves for the indirect control of larger flows.
