Which is the size for drain and vent connections? I means, a valve 3 1/16" must have a port size of?
when to use autoclave connections
Is PR2 Class 2 (slurry test applicable only in gate valves?

400 micron is required only by Total Spec. The std thk. is 150 or 200 micron and, if the adhesion is ok, is enough for any service. Moreover, a bigger thk. is fragile and doesn't add anything to the hardfacing point of view.
