Pressure Relief Valve DB52P2-3X/150UE - Bosch Rexroth R901555075

Not every large hydraulic system runs at high pressure, and many high flow circuits stay below 150 bar. The DB52P2-3X/150UE is tuned for that case and limits between 4 bar and 150 bar while still relieving up to 1500 l/min. Operating pressures up to 315 bar are permitted.

Benefits

• Setting range 4 bar to 150 bar, finely resolvable for circuits of medium rated pressure
• 1500 l/min relieving capacity across the two ports of size 52
• 315 bar permissible operating pressure as a reserve against pressure peaks
• Internal hexagon under a protective cap, the setting stays secured in service
• Pilot-operated poppet valve with NBR seals for HL hydraulic fluid
• 30 kg valve mass, subplate mounting, CE conformity

Application

Circuits of this kind are found in hoists, conveying equipment and plastics machinery with large cylinders and moderate pressure. The valve protects the pump outlet there without the limit pressure having to be set within the wide span of a high pressure valve.
