SD342X Telescopic Flange Eccentric Butterfly Valve：
SD342X telescopic flange butterfly valve is designed based on eccentric structure principle, optimizing the moving track of sealing face during valve opening & closing. The sealing surfaces keep non-contact and friction-free in operation, paired with high-quality NBR sealing material to guarantee stable sealing performance and outstanding abrasion resistance.
This telescopic flange butterfly valve is widely used in water supply, drainage, HVAC and municipal pipeline systems for medium of clean water at 0~80℃, available in PN10 and PN16 pressure grades. It supports multiple actuator configurations including worm gear manual, pneumatic driving types, standard sizes from DN50 up to DN1200 in stock, custom specification available on clients’ requirements. Key advantages of SD342X telescopic flange butterfly valve:
1. Low operating torque for easy opening & closing, labor-saving and energy-efficient during long-term pipeline running;
2. Unique eccentric design enables the disc to get tighter while closing, realizing zero leakage bidirectional sealing effect.
