Directional Spool Valve 4WEH16J7X/6EG48N9ETK4/B10 - Bosch Rexroth R901488537

The pilot-operated 4WEH16J7X/6EG48N9ETK4/B10 weighs 8 kg and draws pilot oil internally, with the control oil return running internally as well. On a subplate mounting to ISO 4401-07-07-0-05 it distributes up to 300 l/min across four ports following spool symbol J.

Benefits

• Weight of 8 kg as a planning figure for manifold and mounting.
• Internal pilot oil routing on supply and return without external X and Y lines.
• Flow of up to 300 l/min in size 16 to ISO 4401-07-07-0-05.
• Operating pressure up to 280 bar with NBR seals and HL hydraulic fluid.
• Control voltage 48 VDC on a connector, 3-pole (2 + PE) according to EN 175301-803.

Application

With no external control oil ports, piping at the manifold comes down to the four working ports. That assumes port P is permanently pressurised and the tank port carries no appreciable back pressure. The 48 VDC control voltage suits plants whose switchgear is built at that level.
