Metal hard seal swing butterfly valve

Simac adopts foreign technology to develop and produce the swing butterfly valve. The special spiral groove structure is adopted inside, which makes the butterfly plate deviate from the valve seat before rotating when opening. When closing, it is first closed in place and then pressed to seal, thus eliminating the friction of the butterfly plate, easy opening and closing, reliable sealing and long service life. Is the traditional butterfly valve technology progress.
