Directional Spool Valve 4WEH16D7X/6EG24N9TSK4 - Bosch Rexroth R900931559

Moving a large double-acting axis safely in both directions calls for a main valve with a clearly defined switching sequence. The 4WEH16D7X/6EG24N9TSK4 works to symbol D with two switching positions and a flow of up to 300 l/min.

Advantages

• Symbol D across four ports fixes the assignment of pump and actuator ports in both switching positions.
• Pilot-operated design with external pilot oil supply and internal return keeps the pilot circuit separate from the main circuit.
• Maximum operating pressure of 280 bar at a flow of 300 l/min in size 16.
• Connection diagram ISO 4401-07-07-0-05 means a swap for another valve of the same size needs no new subplate.
• 3-pole connector (2 + PE) to EN 175301-803 with a 24 VDC supply.

Application

The valve controls lifting, feed and closing axes in presses, power units and heavy special-purpose machinery. It is bolted onto a size 16 subplate and driven through a pilot oil circuit. The NBR seals are matched to hydraulic fluid HL.
