Thanks for the info found them they are genisis valve’s. By the way the valve’s I have a problem with are the one’s I took to the shop to be vip and charged me for unneeded cleaning but did not pick up on the bad seats in the 2 valve’s. It has been very annoying that everytime I try to check my o2 content the air is wide open on or off. No cracking the valve for a slow steady stream. Seems to me a trained so called profesional would pick up on this problem right away!
