A new customer required a Parker Denison R5U (R5U12) relief valve, which was to be mounted directly onto a pump. The valve is now being delivered to the customer.
Bosch Rexroth Proportional Pressure Reducing Valves, Pilot Operated - DRE(E) and ZDRE(E)
The valve types DRE(E) and ZDRE(E) are electrically pilot operated 3-way pressure reducing valves with pressure limitation of the actuator. Operation is effected by means of one proportional solenoid. The solenoid is either controlled via external or via integrated electronics (OBE).
The size of the 1X series valve is 6. The maximum operating pressure for the DRE is 210 bar and 315 bar for the ZDRE. They both have a maximum flow of 30 l/min.
Some of the features of the proportional valve include:
- For subplate mounting.
- Sandwich plate valve.
- Porting pattern according to ISO 4401.
- Valve for pressure reduction in ports A and P1 with pressure limitation.
- Integrated electronics (OBE) with type DREE and ZDREE.
- Low manufacturing tolerance of the command value pressure characteristic curve.
