Usage and features:
Nylon board butterfly valve structure without pin, excellent reduction, self-lubricity, operating torque 40% less than normal butterfly valve. Good abrasion resistance, sealing butterfly valve can be significantly prolongs the service life, compared with the average life-span, line butterfly valve can lengthen 3 times.
Nylon have excellent performance, alkali, salt resistance to erosion and weak organic compounds, adapt to a wide range of inertia. Advanced without pin connections, guarantee the media and metal completely isolated, improve the product' s reliability, simple maintenance of butterfly valves
