Pressure Relief Valve DBW10A3-5X/350YS6SMG24K4B12 - Bosch Rexroth R901440317

A pressure relief valve holds system pressure at the value you set and protects the pump, the lines and the actuators against overload. The pilot-operated DBW10A3-5X/350YS6SMG24K4B12 in poppet seat design covers a setting range of 4 to 350 bar and lets up to 250 l/min flow off to tank.

Benefits

• Setting range 4 to 350 bar on a lockable rotary knob with scale.
• Relief flow of up to 250 l/min in size 10 through the subplate mounting to ISO 6264-06-09.
• Maximum operating pressure 350 bar with NBR seals and HL hydraulic fluid.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• Weight of 4.88 kg with two switching positions across two ports.

Application

The valve is fitted to size 10 power units and control manifolds carrying flows of up to 250 l/min. The poppet seat design keeps leakage low in the closed state, which counts during long holding phases under pressure. The lockable knob with scale fixes the value once it is found, useful where changing personnel operate the machine. NBR seals and HL hydraulic fluid define operation on mineral oil.
