Pressure Relief Valve DB52P2-3X/315YU - Bosch Rexroth R900379002

In the DB52P2-3X/315YU a small pilot stage controls the large main poppet, which yields an accurate cracking pressure from modest adjusting forces. The setting between 4 and 315 bar is made through the internal hexagon with protective cap.

Benefits

• Pilot-operated design for accurate response pressures from 4 to 315 bar
• Internal hexagon with protective cap keeps the setting in place
• Up to 2000 l/min flow at 315 bar maximum operating pressure
• Poppet seat design with low leakage, two ports
• Subplate mounting of size 52, NBR seals, weight 27.3 kg

Application

The valve caps pressure in power units with a high oil flow, such as presses and injection moulding machines. The pilot stage keeps the cracking pressure largely constant across the flow range. It is fitted to a size 52 subplate.
