Description
The rapid stroke of a large press cannot be covered by the pump, since drive power and line sizes would be unaffordable. Instead this valve fills the cylinder directly from the elevated reservoir and passes up to 6700 l/min while doing so.
Benefits
- Flow up to 6700 l/min in size 150, laid out for the rapid stroke of large cylinders.
- Operating pressure up to 350 bar, seat design closing tightly during the pressing phase.
- Version without pre-decompression, for circuits that control decompression themselves.
- Hydraulic actuation, 2 switching positions, 4 ports, flow direction A to B.
- Cartridge valve to thread standard ISO 228-1, NBR seals for HL hydraulic fluid.
- Weight 79.4 kg, for installation in the press head or in the cylinder cover.
Applications
The valve is fitted into hydraulic presses, forging lines and sheet forming machines with an elevated reservoir. During the rapid stroke it opens and lets the cylinder draw oil, during the pressing phase it closes tightly. Since this version has no pre-decompression, the circuit has to control pressure release itself.
