Why is this the best? We start with the standard aluminum casting valve body and then mill out the throat to reduce the restriction by 50%. We also mill the end of the brass fitting to create a bevelled edge rather than the blunt end that blocks the media flow.
PLEASE SEE THE PICS FOR DIRECT COMPARISONS OF OUR SPECIALLY MODIFIED VALVE WITH THE BASIC UNMODIFIED CAST ALUMINUM VALVE.
These changes turn this good metering valve in a great one. Use less air to move your media. Reduce air compressor cycling on and off. Get the job done faster.
We are the only seller offering this greatly improved cast aluminum metering valve because we developed the modifications and we do the machine work ourselves in our shop.
We have been selling blast cabinet and parts washer upgrade kits and components for five years.

Here is just some of the feedback on this HI-FLO valve
Alan P. check VERIFIED PURCHASE
The High Flow Metering Valve was a great upgrade to my Harbor Freight Sandblast Cabinet. The media is consistent and abundant. I can only say the best from Ron Best Tools Upgrade. Shipment was sent out immediately and with all necessary parts to attach to Cabinet.

Finally got my Harbor Freight blast cabinet working like it should. Make sure to follow the adjustment instructions. Super fast shipping even though they just got back from a trip the day before. Very happy with the results and the service! - I installed the metering valve and stripped an entire dirt bike swingarm before lunch, in the HF cabinet which basically didn’t even work before this

The high flo really does make a considerable difference. Well worth the cost. Speeds up
the process considerably. Highly recommended improvement for your blast cabinet!
