The handle no longer fits (rectangular hole worn too big) on the main ball valve for my sprinkler system. I am not good at sizes, but it looks to me like the valve is maybe 1” coming in and 1 1/2” out? By any chance do all 1 1/2” valves have the same rectangular stem that the handle fits over? If not, any idea what brand this is? the handle says 600 wog MATCO 754DT, but google searches don’t find it. The opening in the handle looks to be about 3/8 x 1/4”. Can I just use a vice grip or will I run the risk of screwing up the stem....don’t want to have replace valve because of the handle! I tried to add photos but I chose site album which I guess was wrong?
