H76X-16Q Engineered for reliable one-way flow control in industrial pipelines, the H76X-16Q Wafer Double Leaf Butterfly Check Valve is crafted from high-grade ductile iron (DI) – offering superior strength, impact resistance, and corrosion durability compared to traditional cast iron. Its robust construction ensures long-term performance in demanding operating conditions (working pressure up to 1.6MPa, temperature range -10°C to 120°C). Featuring a double leaf butterfly design, the valve delivers fast response to flow changes, minimizing water hammer and ensuring tight shut-off. The wafer-type connection allows easy installation between flanges without extra space, optimizing pipeline layout efficiency. Equipped with high-quality EPDM soft seals, it achieves leak-proof performance while reducing friction, extending service life and lowering maintenance costs. Designed for low flow resistance, this check valve efficiently handles water, sewage, neutral liquids, and light corrosive media. It is widely applied in water supply and drainage systems, municipal engineering, HVAC, chemical plants, power stations, and industrial piping networks – ideal for preventing medium backflow and protecting equipment safety. Compliant with GB/T standards, the H76X-16Q valve combines rugged reliability with cost-effectiveness. Custom specifications and OEM/ODM services are available to meet specific project requirements. As a professional valve manufacturer with integrated industry-trade capabilities, we provide one-stop solutions from production to after-sales support.
H76W-16P wafer butterfly check valve is double-plate swing non-return valve with wafer clamping structure, installed directly sandwiched between two pipe flanges without extra mating flanges. Under forward medium pressure, two semicircular valve discs push open separately for fluid passing; once backflow happens, back pressure pushes discs close tightly to cut reverse flow automatically. Full stainless steel 304/316 construction delivers outstanding corrosion resistance for corrosive working medium. Compact thickness greatly saves installation space compared with flange check valves.
