Design features >>>
1. Zero leakage: The manufacturing process ensures two-way zero leakage performance for the butterfly valve;
2. Anti-static structure: Conductive springs are placed between the valve stem, body and ball to avoid electrostatic ignition and ensure system safety;
3. The valve seat structure adopts automatic compensation design to ensure reliable sealing;
4. Double eccentric butterfly valve: The butterfly plate and sealing surface quickly separate, reducing friction, and making it suitable for high-frequency operation;
5. The fire protection design meets API607 and other industry standards for fire safety.

Design features of high performance double eccentric butterfly valve >>>
1. Capping: Adopting a balanced pressure root design to prevent the valve stem from coming out, balancing and compressing the seasoning to evenly seal it and prevent leakage. (See Figure ① above)
2. Pressure plate: does not contact the valve seat when opened, has no wear points, reduces torque, and requires relatively small actuator torque. (See Figure 2 above)
3. Insert: Low maintenance cost, easier disassembly and assembly, simply remove the insert to replace the valve seat. (See Figure ③ above)
4. Valve seat: Multiple sealing materials can be selected according to different working conditions. (See Figure ④ above)
