Pressure Relief Valve DB52P1-3X/50UE - Bosch Rexroth R901077830

A circuit with a low set pressure can only be adjusted coarsely with a widely spanned spring. The DB52P1-3X/50UE therefore covers the band from 4 bar to 50 bar and stays finely resolvable there. The relieving capacity of 1500 l/min and the permissible operating pressure of 315 bar are unaffected by this.

Benefits

• Narrow setting range from 4 bar to 50 bar, giving fine resolution at the rotary knob
• 1500 l/min relieving capacity despite the low pressure stage
• 315 bar permissible operating pressure as a safety reserve against pressure peaks
• Rotary knob as the adjusting element, adaptation without tools
• Pilot-operated poppet valve with NBR seals for HL hydraulic fluid
• 28.36 kg valve mass, subplate mounting, CE conformity

Technical data

Application

It is used in low pressure circuits of large installations, for instance flushing and cooling loops, prefill systems of presses and return manifolds with a defined back pressure. Large oil volumes have to be relieved safely there at small pressures.
