Prop-Druckbegrenzung SVT DBEM20-7X/315YG24-8K4V - Bosch Rexroth R901368025
A fixed cut-off pressure is not enough when a process runs through several pressure stages. This proportional pressure relief valve DBEM20-7X/315YG24-8K4V sets the pressure steplessly through an electrical signal, at up to 550 l/min in size 20.

Description
When a machine needs several pressure stages during its cycle, a proportional valve replaces switching between several fixed valves. This size 20 proportional pressure relief valve sets the pressure through an electrical signal and is rated for 550 l/min at a maximum of 350 bar.
Benefits
- Stepless electrical pressure command instead of a fixed mechanical setting.
- Flow up to 550 l/min at a maximum operating pressure of 350 bar.
- Electrical with external electronics, supply voltage 24 VDC.
- Two switching positions on four ports, spool symbol P to T, P to Y.
- Subplate mounting to ISO 6264, FKM seals.
- HL hydraulic fluid, weight 5.28 kg.
Application
Valves of this kind sit in presses, injection moulding machines and test rigs where system pressure changes with the cycle. Control runs through external electronics that convert the command value from the controller into solenoid current. That amplifier module has to be sourced separately.
Manufacturer
Bosch Rexroth lists the valve under material number R901368025. Characteristic curves, command value ranges and the requirements on the amplifier electronics are given in the data sheet for the proportional pressure relief valve (RE 29361) and in the overview RE 07600-B.
