Thermostatic Mixing Valve 1/2 in

The Acorn Engineering Company ET71-1-OTG is a thermostatic mixing valve designed for bathware applications. It features a brass body with 1/2 in NPT inlet and outlet connections. The unit regulates water temperature for safety equipment and drench hose systems.

Integral Check Valves and Gauge

The valve includes integral check valves that prevent cross-flow between hot and cold supply lines. An outlet temperature gauge provides a visual reference for the mixed water temperature. These features support reliable operation in emergency equipment installations.

Suits Emergency Eye Wash and Drench Systems

This valve suits facilities needing tepid water delivery for eye wash stations or drench hoses within the specified temperature and pressure range. It is not intended for applications requiring flow rates above 12 gpm or inlet temperatures outside the 40 to 185 Degrees F limits. Builders needing larger connection sizes should look at other models.

Questions about this item

Will the integral check valves need periodic replacement?

The integral check valves are built into the brass body and have no separate replacement schedule published by the manufacturer.

What limits continuous flow during heavy use?

The 12 gpm flow rating and 125 psi maximum pressure are the first constraints you will reach under sustained demand.

How hot does the valve body get when supplying tempered water all day?

Outlet temperature is capped at 95 °F, so the brass body stays near that temperature during continuous operation.
