By stopping backflow before it reaches downstream equipment, this valve protects system integrity while preventing water hammer.
This component supports general fluid control and fire system applications in alignment with NFPA 13 and NFPA 25 installation guidelines. It also complies with lead-free regulations for safe drinking water systems.
