Getting to Know the Players

Two key players dominate the scene: Rising Stem Valves and Non-rising Stem Valves. But how
do you pick a side? Just like in any good battle, it all boils down to understanding their unique
strengths, appearances, and potential downfalls.

Rising Stem Valves

At a glance, Rising Stem Valves reveal their current position – open or closed. It’s like the knight in shining armor – a beacon of transparency, particularly vital in complex piping facilities.

What’s inside counts too. In this case, the stem nut (the hero behind the scenes responsible for
the stem’s upward or downward movement) is nestled safely within the bonnet or bracket.

As forthe stem threading? That’s external as well, making it a breeze to maintain.
In action, when the handwheel pirouettes, the stem nut joins the dance, rotating in place while the stem makes its ascent or descent. However, every hero has a kryptonite.

For Rising Stem Valves, it’s the need for extra installation space due to the stem extension.

Non-rising Stem Valves

Sometimes, what you can’t see holds the power. Non-rising Stem Valves keep their position – open or closed – under wraps, calling for an indicator to check its status. Its stem nut hides within the valve body, coming into contact with the fluid.

Although this might pose risks of corrosion and erosion, the surprises don’t end there. The handwheel and stem are connected, making for a synchronized operation with no relative motion.

Plus, its compact design means it’s perfect for tight spaces, opening up a wider range of applications.
