Directional Spool Valve 4WEH16R7X/6EG24N9TK4 - Bosch Rexroth R900927833

Seal material and hydraulic fluid have to suit each other, otherwise the seals swell. The 4WEH16R7X/6EG24N9TK4 carries NBR seals for HL hydraulic fluid and on that basis switches symbol R at up to 300 l/min and 280 bar.

Benefits

• NBR seals for HL hydraulic fluid throughout the valve
• Symbol R in three switching positions with four ports
• Up to 300 l/min at a maximum operating pressure of 280 bar
• External pilot supply with internal return, version 6EG24N9TK4
• Size 16, subplate mounting ISO 4401-07-07-0-05, 9.79 kg
• 24 V DC solenoid with a 3-pole connector (2 + PE) to EN 175301-803

Application

In power units running mineral oil HL the material pairing stays predictable over the full service life. If the plant changes to a fire resistant medium, a valve with a different seal kit is required. The external pilot supply lets the pilot stage be fed independently of the main circuit.
