Thermostatic Mixing Valves

Guardian thermostatic mixing valves (TMVs) are built for safety shower and eyewash systems that require consistent, tepid water in compliance with ANSI Z358.1. Designed to mix hot and cold water automatically, they ensure water stays within the safe range of 60°F to 100°F for effective first-aid rinsing. Guardian TMVs deliver fast response, dependable shutoff protection, and stable performance even under fluctuating supply conditions. Ideal for laboratories, industrial facilities, and healthcare environments, Guardian valves help maintain code compliance and protect users during emergencies.
