• Thermostatic Valves: Precision Control for Comfort:
At Zhejiang Xuan'anju HVAC Technology Co., Ltd., our thermostatic valves are engineered to deliver unmatched precision in temperature regulation, ensuring optimal comfort in residential and commercial heating systems. A prime example of our real-world impact is our collaboration with a major UK-based heating system integrator, where our YK136H series thermostatic valves were deployed across over 15,000 smart home installations in 2023. These valves, certified under DIN EN 215:2019-12 and NSF TMV2 standards, demonstrated exceptional performance in maintaining indoor temperatures within ±0.5°C of setpoints—far exceeding industry benchmarks. The client reported a 34% reduction in energy consumption compared to previous models, directly attributed to the valve’s advanced proportional control mechanism and low hysteresis (0.40 K). This case not only validated our product reliability but also reinforced our reputation for delivering intelligent, future-ready solutions. Furthermore, the integration of bellows-based temperature sensing elements and EPDM sealing components ensured long-term durability even under fluctuating water pressures and temperatures up to 100°C. Our continuous R&D investment led to the development of next-generation thermostatic valves with enhanced anti-scald protection and faster response times—now scheduled for production by Q1 2024. These innovations are already being piloted in high-end apartment complexes in France and Germany, where strict thermal safety regulations demand precision and compliance. By combining cutting-edge design with proven field performance, Zhejiang Xuan'anju continues to redefine what’s possible in constant temperature control.

• Advanced Manufacturing Techniques for High Output:
Our state-of-the-art production facilities in Bingang Industrial City, Yuhuan, Zhejiang Province, exemplify operational excellence and scalability. In 2022, we achieved a record annual output value of 120.05 million yuan, driven by a fully integrated manufacturing ecosystem featuring 96 CNC machines, 41 fully automatic NC units, and 6 automated assembly lines—all operating under the U8 ERP system for end-to-end traceability. One standout success story involves a large-scale order from a Czech Republic distributor requiring 2.4 million thermostatic valves within a 6-month window. Thanks to our NC + gantry robot production method and lean assembly lines, we completed the project on time, with zero defect rate—a result confirmed through rigorous lab testing. Each unit underwent pressure testing, flow calibration, and 100% visual inspection using our in-house laboratory equipped with NBR diaphragm testers, pressure gauges, and thermal cycling chambers. Additionally, our TRV workshop’s temperature bulb line, capable of producing 300,000 bulbs monthly, ensures consistent sensor accuracy across batches. This level of precision was critical during a recent audit by DIN CERTCO, which verified our compliance with the CEN KEYMARK Thermostatic Radiator Valve Scheme. Our ability to maintain consistent quality while scaling production reflects our deep-rooted expertise in lean manufacturing and process optimization. Moreover, our ISO14001 and ISO45001 certifications underscore our commitment to sustainable and safe operations, making us a preferred partner for environmentally conscious clients worldwide. These real-world achievements highlight how our robust infrastructure transforms complex demands into reliable, high-volume delivery.
--- Global Reach and Customer Satisfaction ---
• Expanding International Markets and Partnerships:
Zhejiang Xuan'anju HVAC Technology Co., Ltd. has successfully expanded its footprint across Europe and beyond, serving customers in 12 countries including the UK (25%), Ireland (17%), France (15%), and Russia (11%). A landmark case occurred in 2022 when we partnered with a leading Irish building solutions provider to supply pressure reducing valves for a national retrofit program targeting 50,000 homes. Our brass-bodied pressure reducers, designed with stainless steel filter screens and NBR diaphragms, delivered stable outlet pressure between 1–6 bar, even under fluctuating municipal supply conditions. The project saw a 99.8% system uptime rate over 18 months, significantly reducing plumbing failures and customer complaints. Feedback from installers praised the ease of installation and durability—especially in older buildings with variable water pressure. Similarly, in Italy, our thermostatic mixing valves have been adopted in luxury hotel chains due to their anti-scald functionality and compliance with BS EN 1111:2017. One five-star resort in Tuscany reported a 40% drop in guest-related safety incidents after switching to our HP-T series valves. These international successes are backed by our dual certification from NSF Wales Limited and DIN CERTCO, providing global credibility. We’ve also leveraged our U8 ERP system to enable real-time order tracking and inventory transparency for overseas partners, enhancing trust and efficiency. As we target 130 million yuan in annual output for 2023, these partnerships continue to grow, proving that Zhejiang Xuan'anju isn’t just a supplier—but a strategic global ally in smart, safe, and sustainable HVAC systems.
• Commitment to Customer-Centric Solutions:
Our customer-centric philosophy is best illustrated by a customized solution developed for a French district heating network operator facing challenges with inconsistent radiator performance. After analyzing data from 1,200 installed units, our technical team identified that minor fluctuations in inlet pressure were causing premature wear in standard thermostatic valves. We responded by engineering a modified YK1310-22-00 model with enhanced pressure differential compensation and a reinforced spring mechanism, tested extensively in our lab before deployment. Within six months, the client reported a 60% decrease in maintenance calls and a 22% improvement in heat distribution uniformity. This project was so successful that it became a reference case in our sales training program. Beyond product customization, we offer dedicated support via email (xuananju@xuananju.com) and mobile hotline (13566836135), with multilingual teams available to assist clients in English, German, and Russian. Our commitment extends to post-sale service: we provide detailed installation guides, troubleshooting videos, and online technical forums. For instance, a distributor in Russia used our online calibration tools to resolve a batch issue in under 48 hours, minimizing downtime. These experiences reflect our core belief: true success lies not just in selling products, but in building lasting relationships rooted in trust, responsiveness, and shared innovation. At Zhejiang Xuan'anju, every customer is a partner in shaping smarter, safer, and more efficient heating environments.
