Pre-Installation Information

Overview

The Model HL 200 Thermostatic Mixing Valve consists of a liquid-filled thermal motor and a
piston control mechanism with positive shut-off of hot when there is a loss of cold water supply
or thermostat failure. The valve body and cap is constructed of bronze with replaceable corrosion-
resistant components, including a stainless steel piston and liner. The valve comes equipped with
integral check stops that have removable strainers. The valve may be mounted in any position. 

The valve controls temperature within ±3° from a low flow to a maximum flow rate for a given
pressure differential. The maximum inlet temperature of the valve is 200°F (93°C), and the
maximum operating pressure is 125 PSI (860 kPA).

Cabinet:

The optional recess-mounted or surface-mounted cabinet is constructed of 18-gauge

stainless steel with a 16-gauge stainless steel door. The cabinet finish is either stainless steel or
baked white enamel. The optional cabinet window is made of Plexiglass.

Supplies recommended for installation:

• lockable shut-off on the outlet if tempered water is supplied to one or more

remote showers
