6" 350 PSI Grooved Check Valve for Fire Protection
Shipping calculated at checkout
The 6" 350 PSI Grooved Check Valve operates as a critical directional flow control component within commercial fire sprinkler and suppression assemblies, safeguarding systems by preventing unwanted backflow. Designed to install seamlessly into high-pressure piping networks, this commercial fire valve ensures unimpeded forward water flow during an active fire event while immediately sealing against reverse pressure. It fulfills stringent life safety mandates outlined in NFPA 13 for the installation of sprinkler systems and complies with NFPA 25 requirements for periodic backflow prevention device inspection and operational testing.
Engineered for demanding commercial environments, this grooved check valve features a robust, durable body construction capable of withstanding extreme stresses up to its maximum 350 PSI working pressure rating. The mechanical grooved connection design simplifies pipe integration on the job site, significantly reducing installation time compared to flanged alternatives while maintaining a secure, leak-free seal under high-demand operating limits.
