Product Description
Expertly engineered gate valve designed specifically for fire protection system applications. Constructed from durable brass with UL/FM approved flanged end connections for secure installation in wet, dry, or preaction sprinkler systems, standpipe networks, and water spray configurations.
Features an Outside Screw and Yoke (OS&Y) design with a rising stem to allow full pipe bore during operation, resulting in high flow capacity when open. The OS&Y gate ensures bubbletight shutoff when closed to prevent water leakage.
Ideal gate valve for commercial, industrial, and institutional fire protection. Fully customized orientations, dimensions, trim materials like bronze or stainless steel, and accessories available.
Rigorously tested and certified to meet strict performance standards. The brass body, flanged ends, and rugged OS&Y design are purpose-built to provide reliable operation in demanding fire protection environments for years.
