EHAO
Premium grade components calibrated for residential networks and agricultural settings in the Czech Republic.
The Czech Republic stands as one of Central Europe's most robust industrial and agricultural landscapes. With extensive manufacturing corridors in Bohemia and agrarian zones across South Moravia, the demands placed on fluid transmission technology are exceptionally high. Over the last decade, there has been a significant market shift from traditional brass and cast iron alloy systems toward advanced polymeric materials, such as our PVC Bibcock EH06 series.
Environmental variables in regions like Central Bohemia often feature high carbonate water hardness. This makes traditional metal components highly vulnerable to decalcification, oxidation, and internal scaling. The high-performance unplasticized polyvinyl chloride (PVC-U) structure of the EH06 series addresses these pain points directly, guaranteeing zero scaling, zero heavy metal contamination, and an extended operational life cycle exceeding 50 years.
Furthermore, local engineering specifications governed by ČSN European norms mandate strict compliance regarding pressure ratings (PN10/PN16) and structural integrity under cyclic thermal conditions. The EH06 has been formulated precisely to balance high tensile strength with impact resilience, allowing it to withstand Central Europe's sub-zero winter temperatures without structural degradation.
Formulated with advanced UV stabilizers and impact modifiers to prevent mechanical degradation.
Engineered in partnership with the Chinese Academy of Sciences and Zhejiang University.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials/pipe fittings/injection moulds. Especially Ehao Plastic Group is a leader of PVC/UPVC ball valves in the domestic market in China. Since its inception, the company has been supported by the Chinese Academy of Sciences and Zhejiang University in Technology. We have also introduced production lines and computer automatic injection molding machines from Germany. Our products undergo 26 steps of scientific testing and strict quality controls to ensure a 100% ex-factory pass rate. The technical indexes fully accord with DIN8077 and DIN8078 standards and reach a world-class level.
By virtue of the comprehensive advantages of large brand influence, excellent product quality, and distinct marketing strategies, our products have covered most provinces and cities in China and other 28 countries and regions including Europe, America, and Southeast Asia. We have won high praise from both domestic and foreign merchants.
We also manufacture plastic moulds and supply customized materials, samples, and pictures of plastic products (extrusion and injection products). Meanwhile, we can develop and make new products according to customers’ specific requirements. We warmly welcome clients at home and abroad.
The spirit of the Ehao plastic group is "honest, dedicated, innovation and return". We adopt a business model focused on quality for survival, science and technology for development, management for benefits, and service for credit. We offer customers high-quality products, reasonable prices, and excellent services.

| Property Matrix | Ehao PVC Bibcock EH06 | Standard Brass (CW617N) | Standard PP-R Tap |
|---|---|---|---|
| Chemical Corrosion Resistance | Excellent (unaffected by acids, bases, or salts) | Fair (susceptible to dezincification) | Good (susceptible to oxidative agents) |
| Scale & Biofilm Build-up | Zero (due to internal smooth finish, Ra < 0.1 μm) | High (rougher copper surfaces promote adhesion) | Low |
| Temperature Limits | -10°C to +60°C (with thermal insulation jackets) | -20°C to +120°C | 0°C to +95°C |
| Tensile Strength at Yield | ≥ 52 MPa (ISO 527) | ≥ 350 MPa | ≥ 25 MPa |
| Raw Material Sourcing | Virgin high-density PVC-U (lead-free formulation) | Recycled or virgin brass alloys (often contains trace lead) | Polypropylene random copolymer |
Our formulation incorporates specific impact-resistant modifiers and organic calcium-zinc stabilizers that comply with REACH and EU chemical safety directives.
Reduces drag and energy expenditure in industrial circulating pumps, yielding superior flow performance compared to metal valves.
Fully compliant with DIN 8077 and DIN 8078 pipelines, allowing smooth integration into existing systems across Europe.
Exploring real-world engineering integrations of our PVC Bibcocks in Czech environments.
In the southern Moravian agricultural zones, especially near Znojmo and Břeclav, efficient water supply management is key for viticulture and vegetable farming. The PVC Bibcock EH06 is widely deployed in outdoor drip-irrigation networks. Its built-in resistance to UV degradation prevents structural brittleness under continuous solar exposure, while the smooth polymer interior prevents scaling from mineral-heavy agricultural water sources.
For chemical and automotive suppliers located in regions like Pardubice and Ústí nad Labem, fluid control valves must resist chemical corrosion. The EH06's UPVC material makes it resistant to diluted acids, alkaline cleaning mixtures, and industrial salts. This offers chemical plants a cost-effective, long-lasting alternative to stainless steel valves.
Modern housing developments in Prague and Brno require building materials that meet strict European lead-free certifications. Unlike conventional brass taps that can leach heavy metals over time, the lead-free EH06 PVC Bibcock guarantees clean drinking water and aligns with local green building certifications.
Freshwater aquaculture is a vital sector in the Třeboň Basin. Managing filtration loops requires valves that do not corrode in constant moisture. Our PVC bibcocks provide stable, salt-tolerant performance, keeping the filtration loops running smoothly without metallic contamination.
Ehao components are engineered for versatile use across diverse industrial and domestic sectors.
Ehao Plastic Group operates advanced injection molding facilities in China. By using high-speed automated equipment and German-engineered systems, we ensure consistent product dimensions and short production cycles.
To support clients in the Czech Republic and Central Europe, we offer streamlined shipping options through direct rail freight lines connecting major Chinese production hubs to key logistics terminals in Prague and Česká Třebová. This reliable logistics network bypasses maritime bottlenecks, ensuring consistent supply chains for large-scale infrastructure projects.
Our raw material sourcing relies on long-term supplier agreements, shielding our clients from plastic resin price fluctuations. Every batch of PVC and PPR undergoes melt flow index checking and hydrostatic pressure testing before it enters the production line.
From raw material incoming verification to optical inspection and high-pressure sealing tests, we maintain a 100% ex-factory pass rate.
