Overview
1 in. OS&Y Gate Valve controls the flow of water in plumbing and fire protection systems, including fire sprinkler and standpipe systems.

Each 1 in. OS&Y Gate Valve's listings and ratings make it suitable for installation above-ground and underground in many NFPA-compliant fire sprinkler and standpipe systems.

This 1 in. OS&Y Gate Valve may be fitted with external tamper switches for monitoring by a fire alarm control panel. Designed for installation to pipes threaded with National Pipe Thread (NPT). Not suitable for use in potable water systems.
