Product Information

Specification

Thermostatic mixing valve is a reliable and cost-effective solution for delivering tepid water to emergency eyewash or eye/facewash stations. Built with durable solid brass construction, it features an 8.0 GPM flow capacity at 30 PSI, making it suitable for most single-user applications. The valve comes preset to 85°F but includes an adjustable set point for customized temperature control. It ensures user safety with a 5.2 GPM cold water bypass in case of hot water failure and a positive shut-off if cold water is lost. Fully compliant with ASSE 1071, CSA B125.3, NSA/ANSI 372, and cUPC certifications, this valve is engineered for dependable performance in emergency scenarios.
