What is the Difference Between Rising and Non-Rising Stem Gate Valves?
The main difference between rising and non-rising gate valves lies in the visibility of the stem: rising stems move up and down, while non-rising stems do not.
Rising Stem Gate Valve vs Non-Rising Stem Gate Valve
For a better understanding of the differences between rising and non-rising gate valves, we provided a chart below:
| Aspect | Rising Stem Gate Valve | Non-Rising Stem Gate Valve |
| Definition | This type of gate valve has a stem that visibly moves up and down as the valve is operated. | This gate valve has a stationary gate valve, meaning it does not move up and down externally. |
| Working Principle | The stem is externally threaded and capable of moving vertically. As the handwheel is turned, the stem rises and falls. This action indicates the valve’s open and closed position. | The gate moves along the internal threads of the stationary stem. The stem is not moving externally. This feature makes the non-rising stem gate valve conserve vertical space. |
| Advantages | Position indication Maintenance Reliability | Space efficiency Protection Cost-effective |
Which Gate Valve Should You Use?
Gate valves have been utilized across diverse industries. They are recognized for their wide-range applications. However, the decision whether or not you should use a rising or non-rising stem gate valve depends on your preferences.
To help you make an informed decision here’s our recommendation:
Best Application for Rising Stem Gate Valves
These valves are preferred when you need a clear visual indicator of the valve’s position. The goal would be to ensure operational safety and efficiency. Rising stem gate valves are perfect for high-pressure and high-temperature systems. Industries such as oil and gas, petrochemical, and power generation industries could benefit from these gate valves.
Best Application for Non-Rising Stem Gate Valves
The next type of gate valve is your go-to choice suppose you face space constraints. Non-rising stem gate valves have a compact design for easy integration into tight spaces. These valves find their proper place in low to moderate-pressure systems. Thus, water treatment, building services, and general industrial processes are the ideal environments for non-rising stem gate valves.
