OS & Y Gate Valve is preferred for pendent and sidewall type sprinklers. Used for covering gaps in ceilings and walls or to make adjustments. They are defined as local control valves. Generally they are used in water feed lines as interruption valves in vorder to separate (to control) zones in the location. Butterfly valves or rising stem valves are used in order to shut off or to control the flow. The OS&Y valve in full open position is a type of gate valve that does not hinder the flow; the open position enables the observation of the pin moving up and down and allows for electrical tracking with a tracking (supervisory)switch. Compared to a butterfly valve it has less hydraulic losses.
