Gerardo decoded the manufacturer of our 2 1/2 all metal valves
(For future reference) The 2 1/2" all metal angle valves used for the VE vent/purge valves and for some of the VE RGA isolation valves are Kurt J. Lesker Co. valves. These are the ones whose only markings are a hand-scribed "CR60R". These are rated for 300C bake out when closed and while under vacuum on both sides of the seat and have operating closing torque range of 14 - 22 (ft*lb).
