Directional Spool Valve 4WEH 16 J7X/6EG24N9DAL - Bosch Rexroth R978917831

A plug connection is convenient, but in damp or heavily vibrating surroundings it is often the first weak point. The pilot-operated directional spool valve 4WEH 16 J7X/6EG24N9DAL is therefore hard wired through a cable gland and carries up to 300 l/min.

Benefits

• Cable gland instead of a plug connector, fixed wiring with no separable contact in the field.
• Three switching positions to symbol J across four ports.
• Up to 300 l/min at a maximum of 280 bar in size 16.
• External pilot oil supply and external pilot oil return for a self-contained pilot circuit.
• 8.9 kg, solenoid actuation at 24 VDC, NBR seals for HL hydraulic fluid.

Technical data

Applications

Plants in foundries, rolling mills and outdoor installations expose plug connectors to moisture, dust and constant vibration. A cable gland clamps the cable and leaves no separable contact at the solenoid. The trade-off is a longer valve change, since the cable has to be disconnected, but the most common cause of intermittent switching failures disappears.
