Thermostatic Mixing Valve (TMV)

Features include:

• Fully approved by WRAS under the TMV3 scheme to the DO8 specification for basin, shower, bidet, and high pressure bath-fill applications
• Rapid thermostatic failsafe on either cold or hot supply failure protects the user from extreme temperature dangers
• Provides extreme mixed water temperature stability under changing supply conditions
• Available in 15mm and 22mm for group mixing

Specifications:

• Factory temperature setting: 41-43c
• Temperature setting range: 38-46c
• Temperature, hot supply: 52-65c
• Temperature, cold supply: 5-20c
• Minimum hot to mix differential temperature: 10c
• Temperature stability: +/- 2c
• Working pressure, static: 16 bar max
• Working pressure: See charts in detailed images
• Flow rate, minimum: See charts in detailed images

PLEASE NOTE: When selecting the required TMV, it is essential that the valve can provide the flow rate required for the application. Where a single TMV is used for group mixing to supply multiple taps, the valve must be sized to meet the combined demand. An undersized valve may result in insufficient mixed water flow at the outlets. For most installations, a separate 15mm TMV for each tap is recommended. If a 22mm TMV is to be used for group mixing to two or three taps, please check the valve's flow-rate performance against the available water pressure and the anticipated simultaneous demand.
