The prefill valve inputs vast fluid from oil box to oil vat when oil vatenters quickly. It can cut down return flow from oil vat to oil box during increasing pressure process. Pilot control pressure oil opens prefill valve and makes fluid which is at oil vat inside vent back to oil box when oil vat returns.
