In modern fluid handling and process engineering, the transition from traditional metallic valves to high-performance thermoplastic flow control components is accelerating globally. Industrial enterprises, agricultural systems, and municipal water managers are increasingly adopting plastic ball valves (including PVC, UPVC, PP, and PPR) to mitigate the massive cost burdens associated with corrosion, scale buildup, and structural degradation.
Unlike cast iron or brass fittings, engineered polymers resist electrochemical oxidation, chemical degradation from aggressive acids or bases, and microbial scaling. Ehao Plastic Group, a pioneer in Chinese thermoplastic valve manufacturing, recognizes this global transition. Through extensive R&D and strategic engineering, we supply industrial ball valves that endure demanding chemical environments while dramatically minimizing lifecycle operational expenditures (OPEX).
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, pipe fittings, and high-precision injection moulds. Ehao Plastic Group stands as a premier leader of PVC/UPVC ball valves in the domestic market in China, serving as a benchmark for quality and engineering excellence.
Our technological foundation is built upon direct academic and industrial collaboration. Since our inception, Ehao has been supported by the Chinese Academy of Sciences and Zhejiang University in technological innovation and advanced materials testing. To execute these scientific designs with absolute repeatability, we have introduced world-class automated production lines and computer-guided automatic injection molding machinery directly from Germany.
Every single valve produced inside our facilities undergoes an exhaustive 26-step scientific testing protocol, controlling every critical variable from raw resin verification to structural torque and high-pressure burst testing. This rigorous control guarantees a 100% ex-factory pass rate. The mechanical and chemical indexes of Ehao products fully accord with the strict global benchmarks of DIN8077 and DIN8078 standards, securing a world-class tier of performance.
Ehao's engineered plastic valves and piping systems are deployed across diverse global environments, each requiring tailored chemical and mechanical properties. Below are our four core application systems:
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits. Our partnership bridges advanced German engineering and cost-efficient Chinese production to supply customized molds, extrusion, and injection solutions globally.

Exporting to 28 countries, including demanding markets in Europe, North America, and South America, requires compliance with distinct regional standards. Ehao has customized its product lines to accommodate localized specifications:
| Polymer Compound | Standard Reference | Operational Temperature Range | Primary Application Environment |
|---|---|---|---|
| UPVC | DIN 8061 / 8062, ASTM D1784 | 0°C to 60°C (32°F to 140°F) | Water supply, process chemicals, wastewater treatment |
| PP-R | DIN 8077 / 8078, EN ISO 15874 | -10°C to 95°C (14°F to 203°F) | Hot & cold water systems, HVAC circulation |
| PP (Polypropylene) | ASTM D4101 | 0°C to 80°C (32°F to 176°F) | Agricultural irrigation, industrial chemical lines |
Comprehensive size ranges and configurations to meet precise flow path, torque, and pressure limits.
The valve industry is entering a new era characterized by intelligent automation and environmental sustainability. At Ehao, our technical roadmap focuses heavily on these core directions:
Actuator Integration & Automation: Industrial facilities require smart systems that communicate directly with centralized SCADA systems. We are expanding our Double Union valve configurations to integrate directly with electric and pneumatic actuators, facilitating real-time automated remote operation.
Eco-friendly Formulations: In accordance with global carbon reduction initiatives, we are researching bio-based thermoplastic polymers and stabilizer additives that minimize environmental footprints during production without compromising chemical resistance or mechanical performance.
Compact ball valves feature a single-piece body design, providing a lightweight, economical solution for applications where space is limited and piping systems are rarely disassembled (e.g., standard agricultural irrigation). Double Union ball valves feature dual union ends that allow the center body to be unscrewed and removed for maintenance or seat replacement without cutting the pipeline, making them ideal for heavy industrial and chemical processing.
UPVC (Unplasticized Polyvinyl Chloride) contains zero added plasticizers. This makes the polymer significantly harder and more rigid than plasticized PVC, providing higher pressure thresholds, superior chemical resistance to acids and bases, and a broader operational temperature window.
Standard UPVC ball valves are rated for temperatures up to 60°C (140°F). For hot water distribution systems, Ehao recommends our PPR or specialized PP-R configurations, which are structurally rated to handle temperatures up to 95°C (203°F) under pressure in accordance with DIN8077/8078.
Our 26-step system monitors the entire manufacturing process: starting with raw material chemical composition analysis, monitoring temperature consistency during computer-guided injection molding, checking dimensional accuracy with micrometer sensors, and performing hydraulic testing on every finished batch to ensure complete seals under maximum operating pressure.
Yes. Ehao Plastic Group operates a dedicated, high-tech injection mold workshop. We routinely develop custom molds, extrusions, and custom-branded valves according to mechanical drawings, 3D files, or material samples provided by our global clients.
