Thermostatic Mixing Valve – Plumbed In Box
- NSW Health Dept Approved
- A range of stainless steel valve boxes available starting with our standard box which is 305mm square x 75mm deep.
- All boxes have a lockable and easily removable stainless steel access door fitted.
- Ensures rapid shut down of mixed outlet flow in the event of hot, or cold water supply isolation.
Recommended Pressures and Temperatures
| MIXED OUTLET TEMPERATURE | |
| Temperature Adjustment Range | 35°to 45°Celsius |
| INLET TEMPERATURES | |
| Cold Supply | Minimum 5°Celsius Maximum 25°Celsius |
| Hot Supply | Minimum 60°Celsius Maximum 90°Celsius |
| Hot to Mix Temperature Differential for Stable operation | Minimum 10°Celsius |
| Cold to Mix Temperature Differential For stable operation | Minimum 5°Celsius |
| FLOW RATES | |
| To ensure stable outlet conditions | Minimum 4 litres/minute As per Graph 1 |
| DYNAMIC INLET PRESSURES | |
| Hot and Cold Inlet Pressures | Minimum 20 kPa Maximum 500 kPa |
| STATIC INLET PRESSURE | |
| Hot and Cold Inlet Pressures | Maximum 1000kPa |
| INLET PRESSURE RATIO | |
| Maximum inlet pressure ratio for stable operation (Hot:Cold or Cold:Hot) |
10:1 (either supply) |
| NOTE: For optimum operation it is recommended that the hot and coldwater supply pressures be balanced to within +/- 10%. NOTE: Notwithstanding the above, compliance with AS3500 must be maintained. |
