Series e427 and e428 Hydroguard valves automatically mix hot and cold
water to deliver blended water at any desired temperature within a
specified range. The assembly contains an advanced thermal actuator
which maintains the selected water temperature within rigid tolerances
despite temperature and pressure fluctuations in the water supply.

Construction features include a built in shutoff valve for delivery
water, a poppet type mixing valve, a concealed adjustment for raising
and lowering the temperature range, and corrosion resistant parts.

The Series e427/e428 Hydroguard is simply constructed. All parts are
accessible from the front, to facilitate cleaning and maintenance.

The Series e427/e428 Hydroguard is preferred for a wide variety of
applications because of its accuracy, reliability, and economy of water
and energy. It is chiefly used in showers, baths, hospital hydrotherapy
and residential areas, where precise, consistent water temperature is
required.
