RISING STEM BALL VALVE

Rising Stem Valves – Ball, Gate, vs. Non-Rising

Rising stem valves provide a stem that rises or falls as the valve opens or closes. This means that the actuation system converts rotational motion into linear movement of the valve stem when it is in operation. So, unlike its non-rising counterpart, the valve stem in this design indicates the position of the valve disc. In this article, we will review a rising stem gate valve, a rising stem ball valve, a rising stem globe valve, and compare the rising stem valve vs. its non-rising counterpart.
