GATE VALVE is also classified according to the type of stem. Stem is the device
which connects the disk and the hand wheel of the valve. According to the stem
the valves are classified as follows:
The rising stem valve and the
Non-rising stem valve

a threaded shaft which can be rotated using a hand wheel. The stem rises when
the valve is opened which helps to identify the position of the valve. When the
gate valve is closed, the stem descends.

of stem valve includes the non-rising stem valve where the stem remains
stationary. There is no upward movement even when the valve is opened. It is
used in underground tunnels and places where there is little or no
space.
