⭐Hydraulic Eccentric Butterfly Valve
With 38 years of expertise in manufacturing hydraulically controlled eccentric butterfly valves, we specialize in water‑hammer protection for pumping stations and leak‑free pipeline sealing. Our valves feature frictionless eccentric sealing and a dual‑stage hydraulic actuation system, making them ideal for demanding applications such as wastewater treatment, raw water supply, and seawater desalination. They comply with EN 1074 and AWWA international standards, and our factory‑direct approach supports project‑specific customization. Widely used in municipal water supply, wastewater treatment, and large‑scale pumping‑station projects both domestically and internationally. ✅
ZHONGNAN VALVE
🔵Double-eccentric butterfly valve
Featuring a double‑eccentric design💡, it delivers bidirectional pressure resistance with zero leakage. The rubber soft seal is compatible with clean water, wastewater, and media containing small amounts of sand. With flanged connections, it offers convenient installation and maintenance, making it the preferred choice for municipal water‑supply projects. In stock at the factory, it also supports custom fabrication for large diameters and can be directly integrated into project bidding processes.
