When it comes to cooling tower efficiency and performance, valve design plays a bigger role than many realize. One important feature to look for in any cooling tower valve is a positive shut-off function.
A positive shut-off means the valve can completely stop water flow when in the closed position. Unlike standard valves that may leak or allow a slow trickle of water, a valve with a positive shut-off prevents persistent leaking, which can compromise system performance and lead to increased operational costs.
In cooling tower systems, water flow must be tightly controlled. Any leakage—no matter how small—can cause:
Installing cooling tower valves with a positive shut-off helps eliminate these issues and ensures your system operates at peak performance.
Not all valves are built the same. Today’s advanced cooling tower valve designs use innovative features to ensure complete sealing.
An internal guide system helps center the valve disc and position it parallel to the seating face. This precise alignment is key to preventing leaks and maintaining long-term performance.
In addition to the guide system, newer valve designs include improved gaskets that provide a tighter seal. This combination allows for a true positive shut-off—something older or conventional valves struggle to achieve.
Our Vari-Flow valves are engineered specifically for cooling tower applications and include:
These valves are designed not only to stop water flow when needed but to do it consistently, even under changing system loads.
If you’re facing issues with valve leakage, unreliable shut-off, or inefficient cooling tower operation, it may be time to upgrade. Choosing a valve with a positive shut-off feature—like our Vari-Flow valves—can improve performance, reduce maintenance, and save costs in the long run.
