Füllventil SF125K0-1-4X/V - Bosch Rexroth R901161329
On the rapid stroke of a press the cylinder needs more oil than the pump could ever deliver. The SF125K0-1-4X/V prefill valve opens the path to the reservoir and lets up to 3800 l/min pass. It is designed as a cartridge valve and is hydraulically actuated.

Description
On the rapid stroke of a press the cylinder needs more oil than the pump can deliver in the same time. The SF125K0-1-4X/V prefill valve closes that gap by opening the path from A to B as a hydraulically actuated seat valve, passing up to 3800 l/min.
Benefits
- 3800 l/min flow in size 125, sized for the rapid stroke of large cylinders
- Seat valve design, sealing the path when closed
- Hydraulically actuated, no electrical connection is required
- 350 bar maximum operating pressure with two switching positions
- Cartridge valve with a threaded port to ISO 228-1, FKM seals for HL
Applications
The valve is built into the head or manifold of large press cylinders that draw oil from a reservoir mounted above them on the rapid stroke. On the return stroke the same path gives the oil back to the reservoir. The version without pre-decompression assumes that pressure release in the cylinder is controlled elsewhere.
Manufacturer
