The Flame King Overfill Protection Valve with Float Gauge is designed to help provide safer and more controlled propane filling for compatible 20lb propane cylinders. The overfill protection device helps prevent overfilling by closing when the propane liquid level reaches approximately 80% of the tank’s capacity. The built-in float gauge moves up and down with the propane level inside the cylinder, allowing an external gauge dial to display the approximate amount of propane remaining. Made with high-quality materials and UL Listed for added safety and reliability, this valve is compatible with Flame King 20lb propane cylinders, including Models YSN230 and YSN201. IMPORTANT: The purchaser of this product assumes all responsibility and liability to ensure that it is the proper part for the application and complies with all National, Regional, Provincial, or local codes, regulations, and standards, including, but not limited to, the applicable requirements of CGA, NFPA, CFR 49, and Transport Canada.
