Description
If the plant runs on mineral oil of the HL range within the usual temperature band, NBR seals are the fitting choice. The SF125K0-1-4X prefill valve is built that way, releases up to 3800 l/min on the rapid stroke and holds up to 350 bar operating pressure.
Benefits
- NBR seals for mineral oil of the HL range in the usual temperature band
- 3800 l/min flow in size 125, two switching positions
- Hydraulically actuated seat valve, without an electrical connection
- 350 bar maximum operating pressure, passage from A to B
- Cartridge valve to ISO 228-1, weight 47.28 kg
Applications
The valve is used in the prefill circuits of large presses, stretching lines and forging units. It lets the cylinder draw from the reservoir on the rapid stroke and drain back on the return. Compared with the FKM version only the seal material differs, the hydraulics stay the same.
