Great video. I really liked the animations you used to explain the pressure switch.

SOR stands for "Static 'O' Ring", which was part of the original pressure switch design created in the 1950's. The design worked flawlessly, and because the o-ring was static, wear and tear was virtually eliminated!

Hello, on the hydraulic diagram of my boiler the differential pressure valve carries three pipes. One pipe is connected on the delivery pipe of the heaters, the other two pipes are connected on the pump suction. Can you tell me why two pipes are connected to the pump suction? Where can I send him a photo? Thanks

Please explain about connection for this pressure switch

[@สุภัคทิพย์พิทักษ์-ฅ3พ]

The switch has 3 poles. The center pole connects to one pole. But when the pressure is increasing high enough, the center pole changes to connect to other pole.

What it mean SOR?

[@Luiferhoyos]

The company wich manufactures the switches, and the one who uploaded the video

[@Thetrucky69]

Yes but ALL abbreviations have a meaning and that has been explained.

Our letters "SOR" stand for Static-O-Ring! Our founder, Roy Dunlap and Kansas University Physics professor Ben Brown invent the static o-ring pressure switch in 1956
