G1/2 Brass Thermostatic Mixing Valve 3-Way 20–50°C Temp Control
G1/2 Brass Thermostatic Mixing Valve — Precise 3-Way Water Temperature Control
Take full control of your hot water system with this durable G1/2 Thermostatic Mixing Valve. Crafted from solid polished brass and engineered for accuracy, this 3-way blending valve automatically balances hot and cold water to deliver a consistent, comfortable temperature between 20°C and 50°C — perfect for kitchens, bathrooms, showers, and electric water heater systems.
Made in Mainland China.
Key Features
- Automatic Thermal Sensing: A built-in thermal sensing element at the mixing outlet continuously monitors and adjusts the ratio of hot and cold water, delivering a steady, comfortable flow every time.
- Accurate Temperature Control: Designed for hot water systems including electric water heaters, pipe valves, and bathroom fixtures — keeps your set temperature stable even when supply pressure fluctuates.
- Built-In Filters & Safety Device: Integrated inlet filters block sediment and impurities from entering the valve. A built-in safety shut-off automatically cuts hot water flow at 38°C to protect against scalding.
- Solid Brass Construction: Made from corrosion-resistant polished brass for long-lasting durability, a premium gold finish, and easy temperature adjustment.
- Easy Installation: Standard G1/2 thread connection fits most existing hot water systems — no specialist tools required, ideal for DIY home improvement.

Frequently Asked Questions
Q: What thread size does this thermostatic mixing valve use?
A: This valve uses a standard G1/2 thread connection, which is compatible with most domestic water heaters, shower systems, and kitchen or bathroom plumbing fixtures.
Q: What is the output temperature range of this blending valve?
A: The thermostatic mixing valve controls the blended water output between 20°C and 50°C. For optimal performance, the hot water supply should be set between 60°C and 70°C, and the cold supply between 4°C and 29°C.
Q: Does this valve have a safety feature to prevent scalding?
A: Yes. The valve includes a built-in safety device that automatically shuts off the hot water supply at 38°C, helping to prevent accidental exposure to excessively hot water — a great safety feature for households with children or elderly users.
Q: Is this thermostatic mixing valve suitable for electric water heaters?
A: Absolutely. This valve is specifically designed for use with electric water heaters, solar water heating systems, pipe valves, and a wide range of bathroom and kitchen hot water applications.
