What is OS&Y in gate valve?
How it works
-
Handle:The handwheel is attached to the top of the stem, and as you turn it, it rotates the stem.
-
Stem:The stem is threaded and is part of the yoke, which holds it in place. As the handle turns, the stem either rises (opening the valve) or lowers (closing the valve).
-
Gate:The gate is attached to the bottom of the stem. When the stem is lowered, the gate blocks the flow of water; when it's raised, the gate moves out of the flow path, allowing water to pass through.
Why it's used
-
Clear position indicator:The rising stem provides an obvious, visual confirmation of the valve's state (up for open, down for closed).
-
Fire protection:Because of the clear indication, these valves are vital in fire sprinkler systems, as they ensure a system hasn't been accidentally shut off.
-
Slow closing:The design requires multiple turns to close the valve, which helps prevent a sudden pressure surge known as water hammer .
-
Tamper detection:Some systems use a tamper switch on OS&Y valves to trigger an alarm if the valve is turned without authorization.
