HydroGuard Series Tempering Valves with Internal & External Cold Water Bypass
External bypass emergency tempering valve systems consist of an ES Series emergency tempering valve and an independent external cold water bypass. Under normal operation the valve will thermostatically blend hot and cold water to deliver tepid water to emergency fixtures, quickly compensating for temperature variations due to changes in inlet temperatures.
