Logic Cover LFA63EWA-7X/CA20DQMG24 - Bosch Rexroth R900964277

The higher the pressure, the more the tightness of the switching element in its closed condition matters. The LFA63EWA-7X/CA20DQMG24 logic cover controls a 2-way cartridge valve that works up to 420 bar and releases up to 5000 l/min.

Benefits

• 420 bar maximum operating pressure in size 63.
• Flow up to 5000 l/min through the cartridge rather than a spool cross section.
• Flow A to B and B to A with 2 switching positions on 2 ports.
• Spool position monitoring as feedback to the plant control.
• 42.3 kg on a cavity to ISO 7368, driven at 24 VDC.

Applications

The cover is used on manifolds of forming presses, injection moulding machines and test rigs that switch large flows at high pressure. Because the cartridge is built as a seat valve, leakage in the blocked condition stays low. The cavity follows ISO 7368, so cartridge and cover find their place in the existing manifold.
