The bidirectional full metal hard seal butterfly valve is a high-performance valve developed by our company based on the three-eccentric butterfly valve. It addresses the issue of ordinary three-eccentric butterfly valves being unable to fully achieve bidirectional sealing. This valve ensures bidirectional sealing during operation, offering high temperature and pressure resistance, wear resistance, and extended valve service life.

Product Features:

1.The bidirectional full metal hard seal butterfly valve adopts a four-eccentric sealing principle with high machining accuracy, achieving bidirectional zero-leakage sealing.

2.Bidirectional sealing, superior sealing performance.

3.Dual safety construction.

4.All-metal sealing structure design.

5.Replaceable sealing pair structure.

6.Powered load packing system.
