There are 3 operation of sanitary butterfly valve, manually, pneumatic and electric. Manually and pneumatic are popular
pull handle and trigger handle, there are 3 or 4 postions of pull handle, and at least 10 positions of trigger handle. The user can get different disc angle by rotating handle.
Pull handle often together with a blue or black ball in the end of a solid stainless bar.
Trigger handle is popular used in brewery becuase it only need a small using space. triggger multi-position handle with plastic cover or in pure stainless steel.
