The 440179 Temperature Management valve is used on UV disinfection systems with Sterilume high-output (HO) UV lamps. This fully automatic valve is installed on the outlet port of the disinfection system and will discharge a small amount of water to a drain line when the system reaches a preset temperature. This valve is perfect for applications with extended no-flow conditions, as it allows the lamp to operate within its optimal operating parameters. The valve assembly comes complete with 12' of drain line, manufactured with 316L stainless steel, and is available in 1" FNPT x 1" FNPT connections. The drain line can be routed outdoors or to any other suitable drain pipe.
