Explore our high-performance compact valves, ball valves, and sanitary drink taps engineered for heavy-duty industrial applications, municipal lines, and precision home setups.
Ehao Plastic Group is a state-of-the-art, high-tech private enterprise fully integrating the research, development, custom design, and large-scale manufacturing of high-grade construction piping components, PVC/UPVC industrial-grade ball valves, agricultural pipe fittings, and high-precision injection molds. Based in China, we have emerged as a dominant domestic and global industry leader, setting benchmarks for fluid control systems.
Our commitment to technical superiority is backed by deep R&D partnerships with the prestigious Chinese Academy of Sciences and Zhejiang University. By bridging advanced polymer physics with manufacturing automation, we keep our products at the bleeding edge of durability, chemical resistance, and structural integrity.
To assure unmatched consistency across our output, we have deployed advanced, fully automated computer injection molding machines and production lines imported directly from Germany. Combined with our strict inspection protocols, Ehao maintains a flawless standard of quality across the board.
Two-inch PVC pipe fittings represent a crucial diameter in both residential plumbing and complex industrial piping networks. The size balances optimal fluid dynamics with robust mechanical resilience, allowing it to serve a vast array of global sectors:
Ideal for central water filtration entries, main distribution manifolds, and drainage lines, delivering reliable flow with zero chemical leaching.
Built to handle harsh chemical fertilizers and high-pressure cycles in drip irrigation, crop watering, and landscape systems.
Non-toxic, corrosion-proof material formulation ensures optimal aquatic health in marine and freshwater recirculation systems.
Suited for structural conduits, chemical processing pipelines, water-treatment facility loops, and heavy machinery setups.
Ehao Plastic Group's manufacturing process is engineered around strict international benchmarks. By aligning our material science and mechanical designs with DIN 8077 and DIN 8078 standards, we ensure that every valve and fitting performs reliably under demanding thermal and mechanical loads.
| Performance Metric | DIN 8077 / 8078 Requirement | Ehao UPVC / PVC Performance | Industrial Benefit |
|---|---|---|---|
| Hydrostatic Strength (20°C, 1 hr) | ≥ 42.0 MPa | > 45.2 MPa | Resists surge pressures, preventing catastrophic line failure. |
| Thermal Stability (110°C, 8150 hrs) | No cracking / leaks at 4.6 MPa | Exceeds 9000 hrs without deformation | Long-term durability in high-ambient-temperature projects. |
| Tensile Strength at Yield | ≥ 40 MPa | 52 - 55 MPa | Excellent mechanical integrity under high load. |
| VICAT Softening Temperature | ≥ 76 °C | 80 - 82 °C | Expands operational temperature bounds for industrial fluids. |
Every single batch of raw PVC compound undergoes a rigorous, multi-stage testing sequence before it enters our German-engineered injection molding machines. Key stages include:
Ehao Plastic Group's core competitive advantage lies in our comprehensive control over the industrial supply chain. Our industrial complex houses an independent, high-grade mold R&D division. Rather than sourcing standard tooling from third-party manufacturers, our team develops CAD/CAM/CAE designs and machines custom injection molds on-site. This vertical integration provides key advantages to our global partners:
Whether you require standard 2" Octagonal Ball Valves, customized socket profiles, or specialized color paths for regional markets, our German-made manufacturing lines adapt quickly to your project requirements.
As the regulatory landscape moves toward circular economies and reduced environmental footprints, Ehao is investing in sustainable manufacturing. Our technical roadmap focuses on three main areas:
Explore the second part of our range, featuring octagonal compact valves, double union designs, and white/blue socket valves built for residential and industrial water networks.
