THERMOSTATIC MIXING VALVES
The AXION® line of thermostatic mixing valves by Haws® is engineered for blending tempered water in emergency equipment like showers and eyewash fixtures. Constructed from lead-free brass, these valves offer redundant anti-scald protection.
Specifications
- Model 9201H: Suitable for emergency showers and eyewash fixtures with a flow rate of 31 GPM (117 LPM) max and 1 GPM (4 LPM) min. Hot inlet temperature ranges from 120° F to 180° F, and cold inlet temperature ranges from 40° F to 70° F.
- Model TWBS.EWE: Designed for emergency eyewash fixtures with a flow rate of 12 GPM (45 LPM) max and 1 GPM (4 LPM) min. Similar temperature specifications as Model 9201H.
- Model TWBS.HF: For emergency showers and eyewash fixtures with a flow rate of 78 GPM (295 LPM) max and 1 GPM (4 LPM) min. Includes a pressure sensing diverter valve and triple redundant anti-scald protection.
- Model TWBS.SHE: For emergency eyewash fixtures with a flow rate of 74 GPM (280 LPM) max and 1 GPM (4 LPM) min.
Certifications
All models are CSA certified to ASSE 1071, NSF/ANSI 61 & 372, and comply with the California Health and Safety Code 116875 (AB 1953) and applicable sections of CSA B125.3.
Features & Benefits
- Modular brass design with one-piece casting.
- Internal check stops and oversized valve seats.
- Custom shuttle design to prevent valve binding.
- Funnel design for improved temperature control at low flow rates.
- Highest cold water bypass flow rate in the industry.
- Components resistant to lime and calcium.
- Extended 3-year warranty.
Flow Capacities
Each model has specific flow capacities detailed in tables, indicating the relationship between pressure drop (PSI/BAR) and flow rate (GPM/LPM). These tables are crucial for understanding the performance under different conditions.
