The Series e420 HydroGuard

T/P automatically mixes hot and cold water to

deliver blended water within a speciﬁed range. Using an advanced thermal actua-

tor, the Series e420 quickly compensates for temperature ﬂuctuations induced by

water temperature and pressure changes. In the event of cold water failure, the

thermostatic motor virtually shuts of the ﬂow of hot water.

Featuring heavy, cast-brass construction and integral checkstops, all parts of

the e420 Series valve are accessible from the front of the valve and are corro-

sion resistant. The unit also features a metal to metal temperature limit stop, and

all Series e420 valves open in the cold water position to ensure maximum bather

safety and comfort.

The accuracy, reliability and water economy of the Series e420 HydroGuard

make it preferable for applications that require precise, consistent water control:

showers, baths, hospital hydrotherapy and residential areas.

Many HydroGuard

Series e420 valves and shower systems can be selected to meet

the Americans with Disabilities Act (ADA).

Technical Instructions

IS-P-e420

Advanced Thermal Activation

Valve Construction: Thermostatic mixing valve, with heavy cast bronze

body, metal to metal temperature limit stop, integral checkstops and brass stem.

Available with ADA-compliant lever handle.

All HydroGuard

Series e420 thermostatic mixing valves meet above performance

speciﬁcations based on typical operating conditions as stated in ASSE 1016 [45 psi

pressure differential, hot water supply between 140°-180°F (60°-82°C), cold water

supply less than 70°F (21°C)].

If your operating conditions vary from those stated in the standard, performance

may vary as well. Consult your local sales representative or the Powers technical

support department @ 1.800.669.5430, Press "2" to discuss your speciﬁc application.

All Powers thermostatic mixing valves perform to the requirements of standards

ASSE 1016 Type T/P and CSA B125.

Operation n

Hot and cold water enter respective ports in the valve and mix in a chamber con-

taining an advanced thermal actuator (refer to cutaway view). This actuator senses

and maintains the set point of the valve.

Rotating the adjustment handle repositions the shuttle in the cartridge assembly

to produce the desired temperature. The mixed water passes over the shutoff disc

FAILURE TO COMPLY WITH PROPER INSTALLATION

AND MAINTENANCE INSTRUCTIONS COULD

CONTRIBUTE TO THE VALVE FAILURE, RESULTING

IN INJURY AND/OR DEATH.

TO ENSURE THE ACCURATE AND RELIABLE OPERA-

TION OF THIS PRODUCT, IT IS ESSENTIAL TO:

• Properly design the system to minimize pressure and

temperature variations.

• Conduct an annual maintenance program to ensure

proper operation of all critical components.

• Check outlet temperature to ensure it does not

exceed 110°F (43°C). Make sure temperature limit

stop is properly re-set to maximum 110°F (43°C) fol-

lowing valve maintenance or repair. Tampering with

limit stop in any way may result in scalding tempera-

ture causing serious bodily harm and/or death.

Need for Periodic Inspection: Periodic inspection by a

licensed contractor is recommended. Corrosive water

conditions, and/or unauthorized adjustments or repair

could render the valve ineffective for service intended.

Regular checking and cleaning of the valve’s internal

components and check stops helps assure maximum

life and proper product function. Frequency of cleaning

and inspection depends upon local water conditions.
