Pressure Relief Valve DBW 30 B2-5X/315-6EG24N9K4/12=CSA - Bosch Rexroth R978012941

The common case in pressure protection is a subplate valve that caps the circuit and unloads it between cycles. That is what the DBW 30 B2-5X does, over a setting range of 4 to 315 bar, to symbol B, from a 24 VDC solenoid.

Benefits

• 4 to 315 bar setting pressure, protected by a cap over the internal hexagon.
• 650 l/min rated flow at operating pressure up to 350 bar.
• 5.61 kg in size 32 on connection diagram ISO 6264-10-17.
• Two switching positions to symbol B across two ports.
• NBR seals for HL fluid, connector 3-pole (2 + PE) according to EN 175301-803.

Application

Its usual place is the pressure port of a power unit feeding several actuators that should idle without load between cycles. The pilot stage holds the set value over the whole flow range rather than drifting upward as throughput rises. Size 32 requires a subplate to ISO 6264-10-17.
