Tempering Valve
Tempering Valve — High Performance
Orange-cap high-performance tempering for solar, instantaneous, and pumped ring-main systems—same family ratings with extended hot-water supply temperature range.
Key Features
- The plumb-mate tempering valve mixes hot and cold water to deliver tempered water at a constant temperature throughout a building or system
- Ensures safe, constant tempered water to bathrooms and ensuites where outlet temperatures must not exceed 50°C
- Lead-free body — fully compliant with the lead-free requirements of the National Construction Code Volume 3
- Automatic temperature regulation — maintains safe outlet temperatures to help prevent injury or serious burns
- Thermal shut-off protection — if cold water supply is interrupted, the fast-acting thermal shut-off stops flow
- High Performance (Orange Cap): designed for solar hot water systems, instantaneous heaters, and pumped ring main distribution systems
The plumb-mate tempering valve is designed to mix hot and cold water to deliver tempered water at a constant temperature throughout a building or system.
It ensures the delivery of safe, constant tempered water to rooms intended for personal hygiene, such as bathrooms and ensuites, where outlet temperatures must not exceed 50°C.
