I. Project Background

This project is an expansion and renovation project for the water circulation system of a local manufacturing plant in the UAE. It primarily addresses wastewater treatment, circulating cooling water delivery, and water supply and drainage network shut-off control. The UAE has a tropical desert climate, characterized by high temperatures, dryness, and large diurnal temperature variations. Furthermore, the circulating water in the plant contains a small amount of salt, placing high demands on the valves' temperature resistance, corrosion resistance, and sealing stability.

The client found Yuming Valves' official website through an online search engine and sent their project procurement requirements via email. After confirmation of technical parameters, drawings, and qualification documents, the client ultimately signed a contract for bulk purchase of national standard soft-seal wafer butterfly valves, ranging in size from DN50 to DN500, with a pressure rating of PN16, for the on/off control of the entire water treatment network.


II. Core Customer Needs

1. Wide-Diameter, Full-Coverage Matching: A full range of wafer butterfly valves from DN50 to DN500 are required, with a unified PN16 pressure rating, to achieve standardized matching of pipe diameters within the plant, facilitating unified management of spare parts.

2. High-Temperature and Weather-Resistant Adaptability: Suitable for high-temperature outdoor environments in the Middle East, capable of stable operation within a temperature range of -20℃ to 120℃, resistant to slight salt corrosion from circulating water, and the valve body's anti-corrosion coating must resist sand, dust, and humid heat erosion.

3. Stringent Sealing and Leakage Prevention Requirements: Water treatment pipelines must not allow media leakage. The soft-seal structure must be flexible in opening and closing, and reliably sealed, with no dripping even after long-term frequent switching, avoiding water waste and plant ground corrosion.

4. Comprehensive Factory Quality Inspection: All butterfly valves must undergo 100% shell pressure testing and bidirectional sealing performance testing, accompanied by a factory certificate of conformity and test report, meeting local industrial engineering acceptance standards.

5. Strict Dimensional Accuracy Control: Key dimensions of the valves must be accurately measured and verified before leaving the factory to ensure zero deviation in flange connections and pipeline installation, mitigating the risk of assembly errors at overseas sites.


III. Core Product: D71X-16C National Standard Soft-Seal Wafer Butterfly Valve

This project will supply all Yuming national standard D71X-16C wafer-type soft-seal butterfly valves, with specifications ranging from DN50 to DN500 and a uniform pressure rating of PN16. These valves are specifically designed for water supply and drainage, and circulating water treatment applications:

1. Ductile Iron Valve Body + Epoxy Spraying Process: The valve body and exterior are coated with blue epoxy resin electrostatic spraying, providing excellent corrosion and rust prevention capabilities. This perfectly adapts to the high-temperature, dusty, and slightly saline circulating water environment of the UAE, eliminating valve body corrosion and secondary media contamination problems;

2. Reliable Zero-Leakage Soft-Seal Structure: Utilizing high-quality EPDM valve seat seals, ensuring reliable operation... 1. Low closing torque and excellent sealing performance enable bidirectional zero-leakage shut-off, suitable for water treatment systems with frequent on/off cycles, effectively saving circulating water;

3. Multiple actuator options: This supply includes both handle-type and worm gear-type actuators. Small-diameter valves use handle-type butterfly valves for quick manual operation on-site, while large-diameter valves are equipped with worm gear actuators for effortless opening and closing and precise flow regulation, adapting to different pipeline operation needs;

4. National standard standardized design: Strictly adhering to the GB/T13927 industrial valve pressure test standard, the structure and dimensions are uniform, with strong versatility, and can be directly matched with international standard flange pipelines, significantly reducing the difficulty of on-site installation for customers.


IV. Project Quality Control and Delivery Guarantee

1. 100% Water Pressure Sealing Factory Inspection: All DN50-DN500 butterfly valves undergo shell strength pressure testing and bidirectional sealing pressure holding tests after production. Strict pressure stabilization testing is performed according to the PN16 national standard. Each valve has a qualified test record to prevent quality hazards such as leakage, pressure drop, and seal failure. All products are only packaged after all test results meet the standards.

2. Factory Inspection
Since it's inconvenient for customers to inspect the goods at the factory, quality control personnel use calipers to measure and archive the critical installation dimensions of each batch of butterfly valves, including flange outer diameter, structural length, valve body thickness, and bolt center distance. Photos are then sent to the customer for confirmation to ensure dimensional consistency of valves of the same specification and guarantee precise on-site pipeline assembly.

3. Standardized Factory Documentation and Export-Oriented Moisture-Proof Packaging
Each valve comes with a product certificate of conformity, and the product nameplate parameters are clearly displayed. The valve body code is traceable. Valves are individually sealed with dustproof and moisture-proof protective film and packed in fumigated solid wood crates to protect against moisture, impacts, and sandstorms during ocean shipping, ensuring the goods are delivered intact to the UAE project site.


V. Customer Acceptance and Evaluation

The customer highly praised this cooperation: customs clearance was smooth, the goods were packaged intact, and the product quality exceeded expectations. Yuming Valves not only provided one-stop supply for all diameter specifications, but also verified factory dimensions, fundamentally avoiding common installation deviations and valve leakage problems in overseas projects. The complete set of compliant documentation efficiently passed local customs clearance standards. Yuming Valves is a trustworthy valve supplier, and the customer hopes to have the opportunity to visit the factory.
