Exact replacement
Replaced the compressor unloader valve on a gas 5hp twin. Throttle works perfectly and was set at 152-on and 175-off right out of the box. Great deal

Easy installation
This valve will work on most of any type of portable air compressor that has a gas engine. Very easy to install right out of the box. You may want to wrap all of the threads with pipe tape. Other than that it's a great product and I will be looking to purchase two more of them as preventive maintenance for my other compressors. I rate and review all the items I buy honestly and with that being said. I would recommend this to anyone. Thanks

You will need to fine-tune the adjustment via the nuts on the end - once done it's good. It did not come w/ any instructions
Works as advertised - This was used to vent to my unloader valves on the aircompressor. You will need to fine-tune the adjustment via the nuts on the end - once done it's good. It did not come w/ any instructions, however they are available on the net and that would be nice. Very solid feeling.
