Directional Spool Valve 4WEH16E7X/6EG24N9EK4/B10P4,5 - Bosch Rexroth R901135586

Internal pilot supply saves a pipe run, while a shared drain costs switching accuracy. The 4WEH16E7X/6EG24N9EK4/B10P4,5 combines both, taking pilot oil internally behind a 4.5 bar pre-load valve and draining it separately. That keeps 300 l/min at a maximum of 280 bar manageable.

Benefits

• Internal pilot supply with a 4.5 bar pre-load valve and external pilot drain for clean switching times.
• Spool symbol E in three switching positions across four ports.
• Up to 300 l/min at a maximum of 280 bar, hole pattern ISO 4401-07-07-0-05.
• 3-pole connector (2 + PE) to EN 175301-803 at 24 VDC.
• 10 kg with NBR seals for HL hydraulic fluid.

Technical data

Application

It fits manifolds on presses and power units whose return line carries back pressure. A Y line takes the pilot drain, while a pre-load valve provides enough pilot pressure in an unloaded circuit.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16E7X/6EG24N9EK4/B10P4,5 under material number R901135586. Data sheets RE 24751 and RE 07600-B show characteristic curves, installation dimensions and the connection diagram. Operation calls for a Y port at a subplate and a connector to EN 175301-803.
