D341XN worm gear nylon flange butterfly valve WD341JN
Product Introduction:
Turbine nylon plate sewage flange butterfly valveD341XN-10Q worm gear nylon plate flange butterfly valve D341XN-16Q worm gear nylon coated plate flange butterfly valve WD341JN worm gear nylon plate soft seal flange butterfly valve WD341J-10Q/N worm gear ductile iron coated nylon plate flange butterfly valve/worm gear nylon plate sewage special butterfly valve WD341XN worm gear nylon plate rubber soft seal flange butterfly valveIt is composed of a rubber sealed butterfly valve and a ductile iron coated nylon plate. The edge of the valve plate is processed into a spherical surface, polished, and the entire surface of the valve plate is coated with nylon. This nylon is nylon 11, a plant-based coating that meets the hygiene standards for pipelines and is suitable for water supply pipelines, sewage pipelines, and other projects. Nylon coating is rust resistant, which can prevent the growth of bacteria, while also being corrosion-resistant and having a low coefficient of friction.

Product Features:
1. Adopting nylon non pin butterfly plate, it has excellent wear reduction and self-lubricating properties, and the operating torque is reduced by 40% compared to ordinary pin butterfly valves;
2. The sealing surface has good wear resistance (nylon has seven times the wear resistance of copper), which can significantly extend the service life of butterfly valves. Compared with ordinary centerline butterfly valves, the service life can be significantly extended by three times;
3. Nylon material has no toxicity and is antibacterial and enzyme resistant, meeting the increasingly important requirements for green environmental protection;
4. Nylon has excellent alkali and salt resistance, resistance to weak acid corrosion, inertness to organic compounds, and a wide range of adaptability;
5. The no sales connection ensures the isolation between the medium and the metal, improves the reliability of the product, and makes the maintenance of the butterfly valve simple;
6. The connection size between the product and the pipeline flange meets the standards of existing butterfly valve products.
