Directional Spool Valve 4WEH 32 H6X/6EG24N9TS2DAL - Bosch Rexroth R978014843

Some circuits take the pilot oil from a separate source but return it together with the main flow. The 4WEH 32 H6X/6EG24N9TS2DAL covers that combination and passes up to 900 l/min at 280 bar operating pressure.

Benefits

• External pilot oil supply with internal pilot oil return, matching power units that have their own pilot pump.
• 900 l/min flow in size 32 at 280 bar maximum operating pressure.
• Spool symbol H with three switching positions and four ports to pattern ISO 4401-10-09-0-05.
• 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, electrical connection as a cable gland.
• 41.8 kg weight with NBR seals and HL fluid.

Applications

The valve is used in rolling mills, presses and test rigs whose pilot pressure comes from a separate pump. The internal return saves an extra line to tank. Watch the permitted tank back pressure, because the pilot stage is tied to port T.
