Watts 1/4" LFN388-SC Hot or Cold Water Anti-Siphon Vacuum Breaker (Satin Chrome)

Series LFN388 represents a line of vacuum breakers designed to prevent backsiphonage of contaminated water into the potable water supply. The LFN388 features Lead Free* construction to comply with Lead Free* installation requirements. They feature a lightweight, durable “disc float" suitable for temperatures up to 180°F (82°C) which closes the atmospheric vent to prevent spilling under all rates of flow. They are ideally recommended for low flow installations such as laboratory equipment which use small amounts of water. They also contain a durable silicone disc which has high heat and water hammer shock resistance and assures tight seating with the lightest of seating contact. Full Size Orifice - All Series LFN388 valves have a full-size orifice to assure pipe size capacity. Water passages are streamline to provide high water flow with minimal pressure loss.
