Directional Poppet Valve M-4SEW6Y3X/420MG24N9K4QMAG24/B15V - Bosch Rexroth R901352688

A valve that stays in one position under pressure for a long time has to move again on demand and must not pass oil while it is closed. The direct operated M-4SEW6Y3X directional poppet valve in size 6 solves both through a seat seal and withstands operating pressures up to 420 bar.

Advantages

• Operating pressure up to 420 bar in the compact size 6, suited to holding and safety duties in high pressure circuits.
• Poppet design instead of a spool, switching stays reliable after longer standstill periods under pressure.
• Two switching positions to symbol Y across four ports in connection diagram ISO 4401-03-02-0-05.
• Direct solenoid actuation at 24 VDC, with no pilot stage and no separate pilot oil supply.
• Flow up to 25 l/min at a weight of 2.46 kg, so the valve adds little load to the manifold block.
• FKM seals for HL hydraulic fluid, matched to raised temperature demands.

Application

The valve serves holding and clamping circuits, tool clamps and pilot circuits where pressure stands for long periods yet switching must remain possible at any moment. The seat design keeps the blocked port tight, so a cylinder does not creep down while at rest. With 25 l/min in size 6 it also works as a pilot valve for larger pilot-operated valves in the same block.
