What do SC, KY, and KV mean in the image?
KY programmable relay, KV programmable valve
Is SC a mass flow meter? There should be a legend earlier; KY refers to solenoid valves, while KV refers to programmable valves
KV is a cut-off valve, KY is a solenoid valve; I’m not sure what SC means.
It’s obvious that these are diagrams provided by the equipment package supplier. It’s not standard at all. They only know how to sell equipment.
SC: Sample Connection； KY: K stands for time or a timing mechanism, Y represents auxiliary equipment; KY refers to a programmable solenoid valve (an accessory device) whose function is to switch the air path of the programmable valve ； KV: Programmable valve; the symbol indicates it is a cylinder valve.
