Explore our core selection of precision-engineered compact ball valves, double union valves, and water supply components directly from our manufacturing facility.
As a leading high-tech private enterprise, Ehao Plastic Group integrates high-level research and development with modern precision manufacturing of building materials, pipe fittings, and injection moulds. Ehao has established itself as an authoritative market force and a domestic leader in the PVC/UPVC ball valve sector in China.
Our technological advantage stems from strategic alliances with the Chinese Academy of Sciences and Zhejiang University. These institutions provide support in material formulation optimization and fluid-dynamic structural calculations, positioning Ehao at the forefront of polymer piping innovations.
Every product undergoes a rigorous 26-step scientific testing procedure, overseen by internal quality assurance inspectors. This structured process guarantees a 100% ex-factory pass rate. Ehao products meet strict DIN 8077 and DIN 8078 technical standards, matching world-class structural limits for pressure, temperature, and tensile stress resistance.
Ehao also leverages customized plastic mould manufacturing capabilities, allowing us to supply materials, process custom drawings or samples, and develop new injection and extrusion components tailored to custom specifications.
Analysis of emerging material sciences, strict regulatory guidelines, and green engineering trends dictating the future of commercial fluid distribution networks.
With tightening environmental regulations (such as REACH and RoHS), global plumbing infrastructure is transitioning to lead-free calcium-zinc (Ca-Zn) stabilizers in PVC/UPVC compounds, ensuring clean drinking water delivery.
To reduce human error, factories are upgrading to robotic arm handling, centralized raw material feeding systems, and German-engineered injection presses to ensure uniform density and prevent micro-fissures in valve bodies.
Modern system design demands lower pressure drops. By redesigning valve internal pathways and utilizing computer simulations, Ehao minimizes friction losses, reducing pump workload and operational energy costs.
Ehao PVC products deliver reliable sealing, mechanical strength, and chemical resistance across specialized applications.
Modern machine tools can partner with your procurement team every step of the way, assisting from selecting and configuring the right equipment to financing purchases that support long-term growth.
For large-scale infrastructure projects and high-volume wholesale operations, Ehao simplifies supply chains. We provide tailored molding designs, custom colors, and personalized packaging to meet the specific requirements of international distribution centers.
Our business philosophy centers around the principle: "Quality for survival, science and technology for development, management for benefits, and service for credit." We focus on providing high-quality products at competitive prices, backed by responsive post-sale support.
Ehao offers integrated design services for custom fluid handling components. Our in-house mold shop utilizes CNC machining centers to transition design concepts from 3D CAD files to finished steel tooling within brief lead times.
Whether you require custom dimensions, specialized threading standards (NPT, BSPT, DIN), or alternative materials (UPVC, CPVC, PPR, POM), Ehao can manufacture products to your requirements.
