How to Assemble an SV Series Stabilized Connector with Integrated Valve
A non-rotating stem tip rotates independently from the stem and stops rotating as it is driven axially against the orifice sealing surface while the stem continues its rotational and axial movement.
A one piece valve stem rotates and translates along its axis as it is being driven axially into the orifice. The rotational motion of a one piece stem can produce friction as the stem interacts with the seating area, which could result in galling at the seating surface. This is less of an issue in a soft seat valve or if the media provides lubrication.
