Pressure Reducing Valve DRE20-6X/50YMG24-8K4M - Bosch Rexroth R901475022

When one actuator has to run at a lower pressure than the rest of the system, and that value must change during operation, pressure reducing valve DRE20-6X/50YMG24-8K4M takes over. It follows the command value signal of external electronics and controls secondary pressure at a flow of up to 300 l/min.

Benefits

• Electrically adjustable reduced pressure via external electronics, so the command value can be changed while the process runs.
• Flow up to 300 l/min in size 25 at a weight of 6 kg.
• Maximum operating pressure 315 bar at the primary port.
• Three ports and two switching positions with spool symbol B to A, the secondary circuit is relieved to tank on overpressure.
• Subplate mounting to ISO 5781, which keeps the piping inside the manifold.
• Supply at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803.

Application

The valve is used where clamping, pressing or feed forces change from recipe to recipe, for example on machine tools and forming presses. External electronics allow connection to a higher level controller that supplies the command value. At 300 l/min there is enough reserve for fast traverse movements in the same circuit.

Manufacturer
