  • Features of Sanitary Butterfly Valves

    The disc and the sanitary butterfly valve body can be in spheroidal cast iron or in steel. At this valve, when it is in the open position, small localized losses of pressure occur, while strong turbulence and vibrations are created in case of partial closure. Therefore, it is not very suitable for regulation. The maneuvers of the small diameter butterfly valves can be done ...

  • Checking rotary valve clearances

    Rotary valves are precisely machined to accommodate very tight internal clearances. In a smaller standard valve there should be a .003” – .005” gap between the tips and ends of the rotor and the housing / headplate. However, the clearances on many valves are customized to meet the needs of a specific application. For example, in applications with temperature greater than ...
