VIBRATITE 3/4" DN20 Thermostatic Mixing Valve for Solar Water Heaters

Keep your household water at a safe, comfortable temperature with the VIBRATITE 3/4" DN20 Thermostatic Mixing Valve (TMV). Engineered for solar heater systems and general domestic plumbing, this copper-body valve blends hot and cold water automatically to maintain a consistent, pre-set outlet temperature — protecting every household member from unexpected temperature fluctuations during bathing, showering, or hand-washing.

Made in Mainland China.

What Is a Thermostatic Mixing Valve?

A Thermostatic Mixing Valve (TMV) is a precision plumbing component that combines hot and cold water supplies to deliver a stable mixed-water temperature at the outlet. It features a fail-safe mechanism that shuts off water flow rapidly if either the hot or cold supply fails, preventing sudden bursts of extreme-temperature water. This makes TMVs ideal for bathrooms, kitchens, and any shared or public water application where consistent water temperature is a priority.

Key Features

Fail-Safe on Hot or Cold Supply Failure — Automatically shuts off if either supply drops, keeping outlet water at a safe temperature
Stable Mixed Water Temperature — Maintains your chosen temperature within ±2°C even when other appliances draw water simultaneously
Extended Mix Temperature Range — Adjustable from 35°C to 55°C to suit bathing, showering, and hand-washing needs
Versatile Installation — Fits under baths, basins, shower fittings, or inline on exposed hot/cold water mixers
Tamper-Proof Cap — Locks the temperature setting to prevent unauthorized adjustments
Durable Copper Body — Silver and black finish; corrosion-resistant construction for long service life
BSP 3/4" (DN20) Connections — Standard BSP thread for straightforward integration into existing plumbing

Frequently Asked Questions

Q: What size plumbing connection does this thermostatic mixing valve use?

A: This valve uses a 3/4" BSP (DN20) thread connection, which is a widely used standard in domestic and commercial plumbing across many countries. It is compatible with most solar heater systems and standard water supply pipes using BSP fittings.

Q: What temperature range can I set on this thermostatic mixing valve?

A: The mixed outlet temperature is adjustable between 35°C and 55°C. The valve accepts a hot water inlet of 55–80°C and a cold water inlet of 5–29°C, maintaining your selected temperature within ±2°C even when water pressure changes elsewhere in the system.

Q: Can this valve be used with a solar water heater?

A: Yes. This valve is specifically designed for use with solar water heater systems, where stored water can reach high temperatures. It blends that hot water with cold water to deliver a consistent, comfortable temperature at the outlet, making it safe and practical for everyday bathing and washing needs.

Q: Is the tamper-proof cap important?

A: The tamper-proof cap locks the temperature setting in place once it has been configured, preventing accidental or unauthorized adjustments. This is particularly useful in households with children or in shared/public facilities where maintaining a fixed safe water temperature is important.
