✅ Fully Certified: Meets ASSE 1071, NSF 61, and lead-free standards.


Model 9201H, lead free Emergency Valve (patent pending), thermostatically mixes hot and cold water to provide a safe fluid supply for emergency showers and eyewash equipment. The valve contains a secondary high temperature limit valve to provide additional protection to the user in the event of main tempering valve malfunction. 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. A flow rate of 1 to 28 GPM for better temperature control across the operating range. Lowest internal pressure drop for this class of valve (advantage where supply pressure is low). Wax based thermostat technology for fast response time with proven highly reliable temperature control. Highest Cold Water Bypass flow rate in the industry (64% of rated tempid flow rate). Broadest inlet pressure operating range in the industry (minimul outlet variation when cold water is reduced). Modular low-lead brass design with internal check stops. Oversized valve seats resist failures caused by foreign matter. A new and efficient shuttle design eliminates valve sticking. A custom funnel design improves temperature control at low flow rates. Outlet temperature is factory set to 85°F (29°C). Tempered water: High temperature limit is factory set to 90°F (32°C). 0.0 GPM cold water failure rate when tested according to ASSE 1071. Cold water by-pass valves are closed during normal operation, regardless of flow rate. CSA Certified to ASSE 1071, NSF 61, California Health and Safety Code 116875 (AB 1953-2006) and applicable sections of CSA B125.3.

Tech Data

BYPASS Best-in-class cold water bypass flow (65% of rated tempered water flow) means continued protection under adverse conditions.

POSITIVE SHUT OFF Actively suspends hot water flow when cold water supply is lost to protect against scalding.

PRESSURE DROP Lowest internal pressure drop for this valve class – essential where supply pressure is low.

TEMPERATURE MANAGEMENT Paraffin-based thermal actuation technology keeps outlet temperature within tight specifications to prevent scalding and hypothermia.

SHUTTLE DESIGN Superior shuttle design combined with premium material selection eliminates valve binding and reduces maintenance costs.

MIXING CHAMBER Innovative funnel design generates turbulent flow to ensure consistent temperature blending across entire flow range.

DEPOSITS RESISTANT Lime and calcium resistant materials used throughout prevent valve sticking and provide a long service life.

FLOW RATES Flow range of 1 to 31 GPM (117.3 L) provides service for one emergency combination shower or multiple eyewashes, reducing complexity and hardware costs.

LEAD FREE Certified to NSF61 and California Health and Safety Code 116875 (AB 1953-2006).

ANTI-SCALD PROTECTION Redundant anti-scald protection with internal cold water bypass ensures reliable protection. Main tempering valve provides primary protection while backup shutoff valve provides secondary high-temp protection. Internal cold water bypass supplies cold water if hot water supply or main tempering valve fails.

MEDICALLY SUPERIOR RESPONSE AXION’s superior design and technology provide a complete safety solution for increased victim comfort.

EXTENDED WARRANTY 3-year extended warranty based on superior engineering and best-in-class material selection means reliable protection you can trust for the long term.
