Product questions
What is the flow rating of the 157B9122 spool?
The listed spool flow is 40 L/min for each of the P-to-A, P-to-B, A-to-T and B-to-T paths. This is a spool specification, not a guarantee of flow in a complete machine.
What happens at the work ports when 157B9122 is in neutral?
Danfoss lists both A-to-T and B-to-T neutral functions as drained, or throttle open. Check that this neutral behavior is appropriate for the hydraulic circuit before selecting the spool.
Will 157B9122 fit my PVG 32 valve assembly?
The spool has a PVB32 load-sensing shuttle interface and is listed for hydraulic actuation and spring return. A PVG 32 designation alone does not establish fitment: provide the valve identification, equipment model and serial number so the configuration can be verified.
