LEDE 6″ (DN150) Ductile Iron Grooved Butterfly Valve with Tamper Switch ? PN16/300 PSI

Description
The LEDE Model XD381X (6-inch) is an industry-leading fire protection valve designed for seamless integration into Schedule 40 (SCH40) grooved piping systems. This valve serves as a critical zone control component, allowing for system isolation while providing electronic supervision of the valve’s status.
Equipped with a high-torque Gear Operator, the XD381X ensures smooth, slow-close operation to prevent damaging water hammer in the pipeline. The internal Tamper Switch is factory-installed and pre-wired with two sets of SPDT contacts, allowing for simultaneous connection to a fire alarm control panel and a local signaling device. The ductile iron disc is fully encapsulated in EPDM rubber, utilizing LEDE?s patented self-sealing technology to ensure zero-leakage performance and a long service life.

Key Features
Dual-Signal Monitoring: Integrated supervisory switch with two internal sets of contacts (Form C) for remote and local alarm monitoring.
Water Hammer Prevention: Gear-driven handwheel ensures slow closure, protecting the piping system from pressure surges.
Self-Sealing Technology: Features a specialized disc design that provides a bubble-tight seal proportional to the fluid pressure.
Rugged Construction: Body and gear housing made from high-strength Ductile Iron (ASTM A536).
Corrosion Protection: Coated internally and externally with high-quality, Red Fusion Bonded Epoxy (FBE) conforming to AWWA C550.
Easy Installation: Grooved ends compatible with AWWA C606 standards for fast assembly with standard mechanical couplings.
