Flanged OS&Y Gate Valve

The Flanged OS&Y Gate Valve provides a manual isolation point in a compatible fire-water pipe. Select it as part of a coordinated equipment specification, with the connected components identified on the project drawing. The product details below distinguish the offered component from a complete installed system.

The outside screw and yoke arrangement exposes the rising stem as the handwheel operates the gate. This helps distinguish the valve position visually while the flanged ends connect it to the pipework. The valve should be selected as an isolation component, with adequate space above the body for stem travel and access to the handwheel.

Check the flange drilling, face-to-face length and full-open height for the selected size. Confirm any supervisory switch separately, since the bare valve does not establish a monitored installation. Use the specified operating position and maintenance procedure for the project, and verify approvals against the exact model if they are required.

Before purchase, provide the required quantity, connection details and installation location so the supply scope can be checked. Where a model has several versions, the quotation should identify the selected version and any separate accessories. Installation labour, commissioning, pipework and associated equipment are not included unless they are expressly listed in that quotation.

On receipt, compare the delivered item with the order, check visible condition and retain its identification and documentation for the site records. Installation and any functional checks should follow the selected manufacturer instructions and the approved project arrangements. Keep the component accessible for inspection, and use compatible replacement parts when maintenance is required. Any proposed change to the specified component should be reviewed against the connected system before it is fitted.
