Pressure Relief Valve DBW 30 BG2-5X/315YU6EG24N9K4/12 - Bosch Rexroth R978024152

A pump delivering against full pressure between two cycles turns drive energy into heat in the oil. The pilot-operated pressure relief valve DBW 30 BG2-5X/315YU6EG24N9K4/12 takes the pressure away through a built-on directional spool valve and works from 2 to 315 bar.

Benefits

• Electrical unloading through a built-on directional spool valve at 24 VDC.
• Setting range 2 to 315 bar, symbol B, three ports.
• Threaded connection in size 32, maximum operating pressure 350 bar.
• Up to 650 l/min relief flow in the unloaded state.
• Pressure valve in poppet seat design, NBR seals, 6.5 kg, HL hydraulic fluid.

Application

In cycled operation the pump stays loaded between strokes unless something unloads it. The built-on directional spool valve switches the circuit pressureless without stopping the motor. Oil heating and power draw both drop during the pauses.
