A company needs 500 tons of raw materials to produce a batch of Product A, and each ton of raw material can generate a profit of 1.2 million yuan. Through equipment upgrades, the raw materials required to produce this batch of Product A were reduced by $x (x > 0)$ tons, and the profit generated per ton of raw material increased by $0.5x\%$. If the $x$ tons of raw materials saved are all used to produce the company's newly developed Product B, the profit generated per ton of raw material is $12(a-\frac{13}{1000}x)$ million yuan, where $a > 0$.

$(1)$ If the profit from producing this batch of Product A after the equipment upgrade is not less than the profit from producing this batch of Product A before the upgrade, find the range of values for $x$;

$(2)$ If the profit from producing this batch of Product B is always not higher than the profit from producing this batch of Product A after the equipment upgrade, find the maximum value of $a$.
