FAQs

What is OS&Y?

OS&Y stands for Outside Screw and Yoke. This design places the threaded stem outside the valve body, with the yoke supporting the stem. It allows users to visually verify whether the valve is open or closed by observing the stem’s position.

OS&Y gate valves are commonly used in fire protection systems, including sprinklers, hydrants, and standpipes, due to their reliability and clear open/close indication.

Что такое OS&Y?

"Outside Screw and Yoke" (наружный винт и вилочный рычаг) — это конструкция клапана, при которой резьбовой шток (винт) находится снаружи корпуса клапана, а вилочный рычаг (йок) удерживает шток на месте. В отличие от других типов затворных клапанов, положение клапана OS&Y (открыт или закрыт) можно визуально определить по положению штока.

Затворные клапаны OS&Y широко используются в системах пожаротушения, системах гидрантов и стояковых системах. Их способность чётко показывать, открыт клапан или закрыт, делает их важными для безопасности и соблюдения нормативных требований.
