Directional Spool Valve 4WEH16D7X/6EG220N9TK4 - Bosch Rexroth R901008275

On a crowded manifold every port saved counts. This 4WEH16D7X/6EG220N9TK4 takes its pilot oil from outside but returns it internally into the tank channel, at a flow of 300 l/min.

Benefits

• External pilot oil supply with internal return, only one extra port on the manifold
• 300 l/min at a maximum of 280 bar in the ISO 4401-07-07-0-05 interface
• 220 VDC through a 3-pole (2 + PE) connector to EN 175301-803
• Spool symbol D with 2 switching positions and 4 ports
• 9.4 kg, NBR seals for HL hydraulic fluid

Applications

The version is used where a dedicated pilot pump exists but the tank channel carries little back pressure. Pilot pressure stays constant without a second line having to be routed. The version is declared to UKCA under Low-Voltage Directive SI2016/1091.

Manufacturer

Bosch Rexroth lists the valve under material number R901008275. Permissible back pressure in the tank channel is named in data sheet RE 24751, supplemented by RE 07600-B.
