The M-3SEW6C37 poppet valve belongs to the M-SEW Poppet Valves series produced by Bosch Rexroth and serves as an electrically actuated shut-off element in hydraulic automation. With valve size 6 it fits compact manifolds while providing a maximum flow of 25 l/min for medium-capacity circuits. A maximum switching frequency of 15 000 operations per hour at pressures up to 350 bar supports rapid cycle machinery. The solenoid is rated for a 100 % duty cycle so the coil may remain energized continuously without damage, and it draws 30 W, defining the power supply load. The electrical input may vary within ±10 % of nominal voltage, maintaining reliable actuation under line fluctuations. Thermal limits are set by a coil surface temperature of 120 °C, allowing high ambient or oil temperatures without exceeding insulation ratings.
In service, the valve carries protection class IP65, sealing the enclosure against dust and water jets. It can be installed in any position, simplifying layout constraints in complex hydraulic blocks. Interface compatibility is ensured by the porting pattern DIN 24340 Form A together with ISO 4401-03-02-0-05, and correct sealing depends on a mounting surface flatness of 0.01 mm per 100 mm and a surface roughness not exceeding Rzmax 4. Approved hydraulic fluids include HL, HLP, HLPD, HVLP, and HVLPD, and circuit filtration must achieve a cleanliness level of 20/18/15 according to ISO 4406 to protect the poppet seats. The assembled unit weighs 1.5 kg, permitting manual handling during installation and maintenance.
