Thermostatic Mixing Valve With Bottom Water Outlet
GenTant, a professional manufacturer in temperature control valves for over two decades, supplies precision Thermostatic Mixing Valve With Bottom Water Outlet globally. We invite you to review our technical data, request samples, or discuss your application needs to purchase reliable, cost-effective solutions for your projects.
Our robust valves (using CW617N brass) automatically blend hot and cold water to ensure safe, stable temperatures for domestic hot water (DHW) and floor heating systems, effectively preventing scalding risks. Engineered for high accuracy (±2℃） and durability, GenTant Thermostatic Mixing Valve With Bottom Water Outlet is specified by engineers worldwide.
Product Feature and Application
1.1. GenTant Thermostatic Mixing Valve With Bottom Water Outlet is designed to maintain a given liquid temperature in domestic hot water systems (DHW) and floor heating systems.
1.2. Thermostatic mixing valves are equipped with a safety system against scalding with boiling water (the valve shuts off the mixed liquid flow if there is no cold water supply).
1.3. The constant temperature of the mixed water is set by the valve's adjusting knob within the established temperature range.
