Pressure Reducing Valve 3DREE16P-7X/250YG24K31F1V - Bosch Rexroth R901305422

Not every reduced circuit runs far below system pressure, some sit close beneath it. The 3DREE16P-7X/250Y build covers that case and holds the pressure from P to A along a 4...20 mA current command. The external pilot drain keeps the pilot stage clear of return pressure, and up to 300 l/min maximum flow at 315 bar is permitted.

Benefits

• Pressure reduction from P to A with an external pilot oil drain
• 4...20 mA command value, a broken wire shows as a reading below 4 mA
• Up to 300 l/min maximum flow in size 16
• Operating pressure up to 315 bar, hole pattern ISO 4401-07-07-0-05
• On-board electronics, 24 VDC, 7-pole connector (6 + PE) to EN 175201-804
• FKM seals for HL hydraulic fluid, 10.24 kg unit weight, UKCA conformity for EMC SI2016/1091

Application

Typical circuits are main clamping stages on forming machines, test cylinders and auxiliary drives that work only slightly below system pressure. Draining the pilot oil externally stops back pressure in the collecting return from shifting the set value. When replacing, compare the type designation and pressure range of the old valve.
