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.

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.
