View Technical Specifications →Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, pipe fittings, and high-precision injection moulds. Most notably, Ehao Plastic Group is a recognized leader of PVC/UPVC ball valves in the domestic market in China. Since our inception, the company has forged technical development alliances with the Chinese Academy of Sciences and Zhejiang University, utilizing advanced polymer research to optimize material molecular density, tensile properties, and wear resistance.
To assure international-grade execution, we introduced fully automated German production lines and computer-controlled automatic injection molding systems. Each valve, bibcock, and pipe connector undergoes a rigorous 26-step scientific testing regime, ensuring a 100% ex-factory pass rate. Ehao's physical and chemical product indices fully comply with DIN8077 and DIN8078 standards, securing our position at the forefront of the global polymer valve and tap manufacturing hierarchy.
"The spirit of Ehao Plastic Group is 'honest, dedicated, innovation and return'. We adopt the business mode of quality for survival, science and technology for development, management for benefits, and service for credit. We offer customers high-quality products, reasonable price and excellent services."
By leveraging our comprehensive scale, distinct global brand influence, and aggressive quality assurance strategies, Ehao products now support infrastructure across most provinces in China and 28 international markets, including major centers in Europe, Southeast Asia, and the Americas.
The Greater Toronto Area (GTA) and the broader Ontario construction market operate under some of the most demanding environmental and regulatory parameters in North America. Rapid urban development, paired with municipal sustainability mandates like the Toronto Green Standard (TGS) Version 4, demands that building systems drastically reduce carbon footprints while guaranteeing long-term system durability.
Under the Ontario Building Code (OBC) and Health Canada guidelines, lead limits in potable water delivery systems are strictly regulated. Ehao's high-purity UPVC, PP, and Polycarbonate bibcocks and taps contain zero trace lead, providing a structurally stable, non-leaching alternative to traditional brass alloy fixtures in institutional and residential developments.
Toronto winters expose outdoor valves and irrigation connectors to intense thermal shock and ice expansion. Traditional metal fixtures split when water freezes inside. Ehao's proprietary engineering polymers feature elastic deformation thresholds that adapt to volumetric changes, minimizing pipeline rupture hazards.
Ontario's water purification processes use varying concentrations of chlorine and chloramines, which accelerate the dezincification of brass. Ehao's UPVC and PP taps are chemically inert to these agents, guaranteeing constant interior surface roughness (low friction) and preventing biofilm accumulation.
Ehao Plastic Group's high-tech valves and tap systems are designed to provide absolute fluid containment and regulation across diverse operating environments. Our systems are routinely specified for:
Industrial fluid control technologies are shifting rapidly toward non-metallic pipelines to enhance system life cycles and reduce carbon footprint. Ehao is at the leading edge of this shift, ensuring all polymer structures meet rigorous global benchmarks including German DIN, American ASTM, and international ISO standards.
Beyond our catalog configurations, Ehao designs and manufactures bespoke plastic moulds, processing customer-supplied materials, specification drawings, and physical prototypes for custom plumbing applications. With our advanced German injection molding systems and high-throughput production lines, we support large-scale OEM runs for municipal plumbing networks, agricultural irrigation, and custom industrial manufacturing plants.
Challenge: An agricultural cooperative in Ontario's Greenbelt required chemical-resistant and freeze-resistant valves to manage automated fertilizer-injection water loops.
Solution: Ehao's 3/4" PP Taps and UPVC unions were installed across 10,000 meters of lateral lines, resulting in zero chemical degradation and reliable flow control throughout winter operations.
Challenge: Recirculating aquaculture system required non-toxic, non-corrosive components to maintain strict water chemistry for organic fish cultivation.
Solution: Ehao Double Union PVC Ball Valves and non-leaching PP taps were deployed, eliminating heavy metal toxicity risks and ensuring system biosecurity.
Challenge: High-rise washroom plumbing required robust, high-pass-rate shutoff valves compatible with varying municipal pressure zones.
Solution: Ehao’s DIN-compliant compact ball valves were installed across sub-piping networks, reducing pressure drop across zones and providing dependable shutoffs during routine maintenance.
The outstanding structural integrity of Ehao products is the direct result of ongoing material science research. Collaborating with the Chinese Academy of Sciences and Zhejiang University, our research and development labs focus on several key polymer advancements:
By blending advanced TPEs with traditional EPDM seals, Ehao has engineered seat rings and gaskets with superior resilience. This technology prevents valve deformation under extreme hydraulic pressures and ensures a leak-free seal across broader temperature ranges.
Our high-impact PC bibcocks incorporate custom UV-stabilizing agents. This protection prevents molecular chain degradation under intense UV exposure, a crucial requirement for both exterior construction sites and open-field agricultural installations.
From selecting and configuring the right machine for your job to helping you finance the purchase that generates noticeable profits, Ehao works in partnership with leading global industrial suppliers to optimize our engineering capabilities. We maintain rigorous standards, utilizing modern injection mold designs to supply reliable municipal, industrial, and agricultural plumbing components.
Our collaborative manufacturing processes allow us to offer tailored product specifications for specialized industrial systems, ensuring every fluid control component performs to the exact tolerances required by high-demand operations.

View Technical Specifications →Unlike brass, polymer fixtures (such as UPVC and PP) are lead-free and immune to dezincification caused by chemical disinfectants (chlorine/chloramines) in the municipal water supply. Additionally, engineered polymer fixtures provide better thermal expansion tolerances during winter freeze-thaw cycles, reducing the likelihood of pipe ruptures.
Ehao’s manufacturing processes are certified to meet DIN8077 and DIN8078 standards. Each unit goes through a comprehensive 26-step testing workflow, including hydrostatic pressure tests, material stress analysis, and dimension checks, ensuring a zero-defect production run for international shipments.
Yes. Ehao Plastic Group integrates specialized mold design and production, allowing us to build customized extrusion or injection-molded components based on engineering drawings, CAD models, or physical prototypes provided by clients in the Toronto and global markets.
Double-union PVC ball valves feature union connections on both ends. This design allows technicians to unscrew the center valve body for maintenance or cleaning without cutting into the pipeline, reducing system downtime and replacement costs.
