• Key Products: Thermostatic and Pressure Reducing Valves:
At the heart of Zhejiang Xuan'anju HVAC Technology Co., Ltd.’s success lies its innovative, high-performance product portfolio tailored for modern heating and hot water systems. The company specializes in thermostatic valves, pressure reducing valves, safety valves, and mixing valves—each engineered for reliability, energy efficiency, and user safety. The Automatic Thermostatic Valve (TRV), for example, is designed to maintain precise indoor temperatures between 7°C and 28°C with a hysteresis of just 0.40 K. Its bellows-based temperature sensing mechanism responds within 20 minutes, adjusting water flow in real time to match room conditions. A real-world case in point: in 2022, Xuan'anju supplied 150,000 TRVs to a German housing cooperative managing 12,000 apartments. Post-installation monitoring showed a 19% reduction in heating energy consumption across the network, directly attributed to the valves’ accurate temperature regulation. Similarly, the Pressure Reducing Valve ensures stable water pressure in multi-story buildings. With a factory preset of 3 bar and adjustable range of 1–6 bar, it prevents pipe bursts and noise issues. In Ireland, a 2023 residential development in Dublin faced recurring plumbing failures due to fluctuating municipal pressure. After switching to Xuan'anju’s brass-bodied pressure reducing valves, the building reported zero pressure-related incidents over 18 months. The Safety Valve, rated for pressures up to 10 bar and operating temperatures from 5°C to 110°C, automatically vents excess pressure to prevent system failure—a critical feature in Russian district heating networks, where extreme winter conditions demand robust safety measures. Additionally, the Thermostatic Mixing Valve (TMV) offers anti-scald protection: if cold water supply fails, it instantly shuts off hot water flow. This feature proved lifesaving during a 2023 incident in a UK care home, where a sudden cold water outage was detected and isolated by Xuan'anju’s TMVs, preventing any scald injuries. These products are not only certified but also continuously developed—Xuan'anju is set to launch new smart-enabled valves by Q1 2024, integrating IoT sensors for remote monitoring and control.
