Directional Spool Valve 4WEH16M7X/6EG24ES2K4/B10 - Bosch Rexroth R900973672

Filters, coolers and long pipe runs create counter pressure in the return that the pilot stage should never see. Pilot-operated directional spool valve 4WEH16M7X/6EG24ES2K4/B10 drains pilot oil separately while carrying up to 300 l/min at 280 bar.

Benefits

• External pilot oil return, the pilot drain bypasses back pressure in the main return.
• Internal pilot oil supply, no separate pilot pressure line required.
• Spool symbol M, three switching positions across four ports.
• 300 l/min in size 16 at a maximum of 280 bar.
• 10.88 kg, subplate mounting ISO 4401-07-07-0-05, 24 V DC.

Application

The valve sits in power units of injection moulding and machine tools whose return runs through filters and oil coolers. Its own pilot drain keeps switching times steady even as a filter loads up. Pilot supply comes from the main circuit, which saves a line.
