Product Description

 

Product Description

Introduction:

The hard-seal butterfly valve, featuring a triple-eccentric design and multi-layer hard/soft seals, ensures durability and energy efficiency. Comprising a valve body, disc, seat, stem, and drive mechanism, it's ideal for pipelines in metallurgy, power, petroleum, chemicals, gas, and water systems.

Advantages:

• The 815 and 830 series American Standard Butterfly Valves feature a double-flange and three-eccentric structure, while the 815L and 830L series feature a lug-style design with a single-flange structure and threaded holes around the valve body. These valves are widely used in pipelines for petroleum, chemical engineering, industrial water treatment, high-rise buildings, and water supply and drainage systems.
• The main features include:
• The three-eccentric structure ensures reliable sealing performance, with the butterfly plate disengaged from the sealing seat during opening, eliminating uneven load on the sealing seat and extending service life.
• The valves offer reliable sealing performance, with advantages of high-temperature resistance, wear resistance, and corrosion resistance.
