Pressure Relief Valve DBW10B2-5X/200YS6EG125N9K4R12 - Bosch Rexroth R901583940

A pressure relief valve defines at which pressure a circuit blows off, and a mounted solenoid valve can additionally unload it. This size 10 valve combines both. The adjustment range runs from 4 to 200 bar, up to 250 l/min are discharged and the permissible operating pressure is 350 bar.

Benefits

• Adjustment range 4 to 200 bar through an internal hexagon with protective cap
• Flow up to 250 l/min at an operating pressure of up to 350 bar
• Pilot-operated seat valve that closes tight when shut
• Electrical unloading through a solenoid stage at 125 VDC
• Port pattern ISO 6264-06-09 with 2 ports, symbol B
• Connector, 3-pole (2 + PE) according to EN 175301-803, NBR seals, UKCA conformity, mass 5.2 kg

Applications

The valve protects pump circuits in power units, presses and test rigs. The solenoid stage lets the pump idle without pressure during start up and pauses, which cuts drive power and oil heating.
