Directional Poppet Valve M-4SED6D1X/350CG24K4QMBG24/B20 - Bosch Rexroth R901223832

A spool valve has clearance leakage by design, a poppet valve does not. The direct operated M-4SED6D1X/350CG24K4QMBG24/B20 therefore uses a seat and holds a pressurised axis in size 6 at up to 25 l/min and a maximum of 350 bar.

Benefits

• Poppet seat design instead of a spool, tight shut-off even at 350 bar maximum operating pressure
• Reliable switching also after longer standstill periods under pressure
• Direct solenoid actuation at 24 VDC, two switching positions on spool symbol D
• Flow of up to 25 l/min across four ports, subplate mounting to ISO 4401-03-02-0-05
• Weight of 2.46 kg in size 6, NBR seals matched to HL hydraulic fluid

Application

The typical use is on clamping equipment, presses and lifting gear whose load is held for hours or days. Because no oil escapes across a spool clearance, the pump does not have to top up and pressure stays where it was. The subplate mounting to ISO 4401-03-02-0-05 makes the valve a direct replacement for a spool valve of the same size.
