The NIBCO Press System® bronze gate valve features a screw-in bonnet for service where infrequent maintenance is required. The gate valve is designed with press-to-connect end connections with an inboard bead and EPDM O-ring with leak detection for quick and easy copper to copper joinery. Properly applying pressure from a press-fit tool tightens the O-ring onto the tube, ensuring a clean, permanent, watertight seal in seconds, with no flame, solder or flux. The gate valve is constructed of highmore quality lead-free* dezincification-resistant (DZR) Performance Bronze® silicon alloy per ASTM specifications. Rising stem gate valves are used when positive shutoff is required and a quick visual indicator of open/closed position is needed. The NIBCO Press System is user friendly, quick and easy to install. When properly crimped a unique “N” witness mark is clearly visible. The lead free HydraPure® Performance Bronze® gate valve is specifically designed for use in systems that deliver water for human consumption.
