Description The LEDE Model XD381X-100 (4-inch) is a high-reliability isolation valve specifically engineered for the fire protection industry. This valve features Grooved Ends compliant with AWWA C606, allowing for rapid and secure assembly with standard mechanical couplings on Schedule 40 (SCH40) pipes. The valve is equipped with a high-performance Gear Operator that provides a slow-close mechanism to prevent the risk of water hammer in the fire main. It features a built-in Supervisory Tamper Switch pre-wired to the internal gearbox. This allows for immediate notification to the Fire Alarm Control Panel (FACP) if the valve is moved from its fully open position. The ductile iron disc is fully encapsulated in EPDM rubber, ensuring bubble-tight shut-off and zero-leakage performance under high-pressure conditions. Key Features Integrated Supervision: Pre-installed dual-contact (SPDT) tamper switch for reliable electronic monitoring of the valve position. Durable Sealing: EPDM-coated ductile iron disc provides 100% leak-proof sealing and resists scale buildup. Anti-Water Hammer: Manual gear operator ensures controlled opening and closing speeds to protect system integrity. High Pressure Rating: Rated for 300 PSI (PN16) service, meeting the demands of modern high-rise fire systems. Corrosion Protection: Coated internally and externally with a high-visibility Red Fusion Bonded Epoxy (FBE). Certified Quality: Fully UL Listed and FM Approved, ensuring compliance with international fire safety codes.
