Introduction to SD343H-10/16C Hard Seal Expansion Butterfly Valve
SD343H-10/16C hard sealed telescopic butterfly valve is suitable for regulating flow and intercepting media on water supply and drainage, gas pipelines in food, medicine, chemical, petroleum, power, textile, papermaking and other industries with temperature ≤ 80 ℃ and nominal pressure ≤ 1.6MPa. It has the function of compensating for pipeline thermal expansion and contraction.
Characteristics of SD343H-10/16C hard sealed telescopic butterfly valve
1. Novel and reasonable design, unique structure, light weight, easy operation, and rapid opening and closing;
2. In addition to regulating and intercepting the flow, compensating for the thermal expansion and contraction caused by pipeline temperature differences, the telescopic butterfly valve can also provide convenience for valve installation, replacement, and maintenance.
3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.
