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.

Technical data

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.
