SR-FSV-OSY-150
OS&Y Gate Valve (Flanged)
Rising-stem OS&Y gate valves give an at-a-glance visual indication of open/closed status — critical for fire-riser isolation points that must never be left inadvertently shut. Bronze-mounted wedge and seat rings resist seizing over years of standby service.
UL Listed (on request) FM Approved (on request) IS 780
- Visual open/closed position indication by design
- Bronze-mounted wedge for smooth, long-life operation
- Optional supervisory tamper switch for monitored systems
