Hertswood started slowly and almost fell behind, Simon Englander with a clearance off the line but they pushed on from then.
Some great football found Weinstein in space up front, he took on the defender, rolled it onto his left foot before slotting into the far corner to mark his debut with a goal.
1-0 became 2-0 soon after as Josh Cohen played a beautiful ball over the top of the defence from out wide to find Alkalay who managed to get a header just past the keeper and into the top corner.
The second half was much of the same with some great football being played from the Vale.
Raiders pulled a goal back with 14 minutes to go as a through-ball found its way through to their striker but it never really looked in any doubt.
Jubilant Hertswood joint-manager Jacob Emanuel told JC Sport: "It was a much-needed win and a deserved three points."
