Description

The Zurn Wilkins Double Detector Check Valve with Grooved Butterfly Valve assembly installs within the main water supply line of commercial, industrial, and institutional fire suppression systems. This assembly prevents dangerous backpressure and backsiphonage from contaminating the potable water supply while maintaining continuous system readiness. Its integrated double detector configuration provides early detection of backflow or unauthorized water usage.

This assembly satisfies stringent regulatory requirements under NFPA 13 for fire sprinkler system installation and NFPA 25 for water-based fire protection system inspection, testing, and maintenance. It also meets code compliance for metered fire protection systems.
