hawkins cooker safety valve in stock

I installed this safety valve on a vintage PC 2340 Universal 4 qt pressure cooker to replace the failed one. It comes with no instructions for installation, which shouldn"t be a problem, but is equipped with a washer that was not present on the old one that was removed. I installed the washer on the outside of the lid, in the normal arrangement between bolt, washer and nut, only to find that it leaked that way. Tried tightening it down super tight, still no joy. Removed the washer and cinched it down well and it sealed up as it should. Upon further examination, I noticed that the washer may work as a spacer on the inside of the lid, since getting a good hold with a wrench on that side, without stripping the hex head, is difficult as it sits into a recessed area. I"m leaving it as is for now, since it"s working again, but if you run into a problem tightening things down sufficiently, you might try using the washer as a spacer on the inside of the lid. Be careful because after a few failed tries to tighten things down, the hex head can easily round over, making it very difficult to get a good hold with a wrench. Subtracted one star for lack of instructions.

The pressure relief valve is a warning device that is designed to provide both visual and audio signals to indicate that the vent pipe has been blocked and is no longer regulating pressure and there is excessive pressure in the cooker.
