DBDH6P Hydraulic Direct Controlled Pressure Relief Valve
 

Pressure Relief Valves of type DBD are direct operated seat valves. They are used for limiting a system pressure.

The valves basically consist of sleeve, spring, poppet with damping piston (pressure rating 25 bar - 400 bar) or ball (pressure rating 630 bar) and adjustment type. The system pressure can be set steplessly via the adjustment type. The spring pushes the poppet or the ball onto the seat. Channel P is connected to the system. The pressure existing in the system acts on the poppet surface (or the ball). If the pressure in channel P exceeds the value set at the spring, the poppet or the ball opens against the spring. Now, hydraulic fluid from channel P flows into channel T. The stroke of the poppet is limited by the embossing.

In order to achieve good pressure adjustment over the entire pressure range, the entire pressure range has been divided into 7 pressure ratings. One pressure rating corresponds to a certain spring for a maximum operating pressure that can be set by means of that spring.
