Gate valves with rising vs non rising stem

Rising stems are fixed to the gate and they rise and lower together as the valve is operated, providing a visual indication of the valve position and making it possible to grease the stem.  A nut rotates around the threaded stem and moves it.  This type is only suitable for above-ground installation.

Non-rising stems are threaded into the gate and rotate with the wedge rising and lowering inside the valve.  They take up less vertical space since the stem is kept within the valve body.  Our company offers gate valves with a factory-mounted indicator on the upper end of the stem to indicate the valve position.  Gate valves with non-rising stems are suitable for both above-ground and underground installations.

The majority of range are designed with non-rising stem, but we also offer gate valves with rising stem for water, wastewater and fire protection applications.
