Directional Spool Valve 4WEH16F7X/6EG24NK4 - Bosch Rexroth R901033222

The spool symbol decides which centre position an axis takes up when the solenoid is de-energised. The pilot-operated 4WEH16F7X/6EG24NK4 in size 16 is built to symbol F and carries up to 300 l/min at a maximum of 280 bar.

Benefits

• Three switching positions to symbol F, defined across four ports.
• Up to 300 l/min on the size 16 port pattern ISO 4401-07-07-0-05.
• External pilot oil supply and external pilot oil return, independent of how the working pressure behaves.
• Maximum operating pressure 280 bar with NBR seals for HL hydraulic fluid.
• 9.85 kg, solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803.

Technical data

Applications

In systems with several consumers on one pump, the centre position decides whether an idle axis releases the flow for the others or blocks it. Symbol F assigns this size a fixed arrangement of the four ports, which has to be known when the manifold is laid out. Subplate mounting to ISO 4401-07-07-0-05 keeps the valve interchangeable in the block with other symbol variants of the same series.
