Valve operating principle:
The Haws Corporation 9201E Emergency Valve thermostatically mixes hot and cold water to provide a
safe fluid supply for emergency showers and eyewash equipment. Additionally, to ensure a fail-safe water
supply for emergency shower and eyewash stations, a series of cold water by-pass valves open in the
event of hot water pressure loss.
Valve features:
- Paraffin filled thermostat with industry leading response time.
- Tempered water: Temperature is factory set to 85°F (29°C).
- Tempered water: High temperature limit is factory set to 90°F (32°C).
- Cold water by-pass valves open if hot water fails.
- Actively suspends hot water flow when cold water supply is lost to protect against scalding.
- Cold water by-pass valves are closed during normal operation, regardless of flow rate.
Valve sizing:
The flow capacity table shown below contains discharge flow rates @ 85°F (29°C) outlet temperature with
the valve tested under the conditions described by ASSE 1071.

Valve specifications:
- Maximum operating pressure: 125 PSI
- Minimum / Maximum hot water temperature: 120°F / 180°F (49°C - 82°C).
- Tempered water temperature adjustment range: 60°F 90°F (15°C - 32°C)
- Compliance/Listings: ASSE 1071 and applicable sections of CSA B125.3.
IMPORTANT
To ensure the proper operation of the 9201E valve it is essential to:
- Properly size the valve for each application.
- Keep the outlet temperature set between 6F and 90°F (15°C - 32°C).
- Haws recommends a weekly testing and recording of the outlet water temperature.
Failure to comply with installation and/or maintenance instructions could result in
valve failure.
