Produktuaren Deskribapena

Proportional Pressure Relief Valve DBE

The DBE series proportional pressure reducing valve can smoothly set the system pressure through the operation of a proportional solenoid, meeting different working requirements. The characteristics of this product include precise control, stability and reliability, and easy to maintain. Proportional pressure reducing valve DBE is available in multiple models and specifications to satisfy different needs. For example, Huade Hydraulic produces models such as the DBE10-30B/315YMDREM and DBE20-30B/200XYM proportional pressure reducing valves, which have different working pressure ranges and flow characteristics, allowing users to select according to their needs.

Product Feature And Application of Proportional Pressure Relief Valve DBE

Features:

▶For subplate mounting

▶Encased in block

▶Optional additional maximum pressure limitation by means of a spring loaded pilot control valve

▶Valve and electronic control form one source

Application:

The DBE series proportional pressure relief valve are widely used in various hydraulic systems that require precise pressure control, such as construction machinery, metallurgical equipment, shipbuilding, and other fields. They play a crucial role in these fields, enhancing the stability and reliability of the systems.

Function and section of Proportional Pressure Relief Valve DBE

These valves basically consist of the pilot control valve (1) with proportional solenoid (2) and the main valve (3) with main spool insert (4).

Type DBE:

The adjustment of the pressure is command value dependent via a proportional solenoid (2). The pressure present in port A acts on the underside of the main spool (4). At the same time this pressure acts on the spring loaded side of the main spool (4) via orificies (5). The hydraulic force acts on the pilot poppet (6). When the hydraulic force over comes the solenoid force then the pilot poppet (6) opens. Due to the fact that the pilot oil can now flow to tank via port Y, a pressure drop occurs at the main spool (4) which acts on the main spool and lifts it against the force of the return spring . The connection from A to B is opened and there is no longer any increase in pressure
