OS&Y (Outside Screw and Yoke) globe valves are designed with a stem and handle that work in tandem due to their threaded connection. When the handle is turned, it directly moves the stem, which, in turn, raises or lowers the valve disc. The external screw mechanism, visible on the outside of the valve, allows for straightforward operation and easy monitoring of the valve’s position. This design is particularly beneficial in applications where visual confirmation of the valve’s status is essential for safety and operational purposes.
