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.\u003c\/p\u003e\n\n\u003cp\u003eMade in Mainland China.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is a Thermostatic Mixing Valve?\u003c\/h3\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFail-Safe on Hot or Cold Supply Failure\u003c\/strong\u003e — Automatically shuts off if either supply drops, keeping outlet water at a safe temperature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStable Mixed Water Temperature\u003c\/strong\u003e — Maintains your chosen temperature within ±2°C even when other appliances draw water simultaneously\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Mix Temperature Range\u003c\/strong\u003e — Adjustable from 35°C to 55°C to suit bathing, showering, and hand-washing needs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile Installation\u003c\/strong\u003e — Fits under baths, basins, shower fittings, or inline on exposed hot\/cold water mixers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTamper-Proof Cap\u003c\/strong\u003e — Locks the temperature setting to prevent unauthorized adjustments\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable Copper Body\u003c\/strong\u003e — Silver and black finish;

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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this valve be used with a solar water heater?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the tamper-proof cap important?\u003c\/h4\u003e\n\u003cp\u003eA: The tamper-proof cap locks the temperature setting in place once it has been configured, preventing accidental or unauthorized adjustments.
