Pressure Relief Valve DBW30A2-5X/315S6EG24N9K4R12=CSA - Bosch Rexroth R900976974

A valve that cannot take the whole delivery of a large pump drives pressure above the set value during relief. The pilot-operated DBW30A2-5X/315S6EG24N9K4R12=CSA is laid out for size 32 and 650 l/min and limits from 4 to 315 bar.

Benefits

• Relief flow of up to 650 l/min through the subplate mounting to ISO 6264-10-17
• Setting range 4 to 315 bar, adjusted on an internal hexagon with protective cap
• Maximum operating pressure 350 bar with HL hydraulic fluid and NBR seals
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
• Weight of 7.04 kg in size 32, spool symbol A

Technical data

Application

The valve sits in the main circuit of power units delivering up to 650 l/min, as found in presses and large machine tools. Adjustment on an internal hexagon under a cap keeps the value from being turned in rough service. The poppet seat design keeps leakage low when the circuit stands under pressure for longer periods.
