In most applications, a brass ball valve can last eight to 10 years. Understanding four factors that can affect a brass ball valve’s lifespan will help you keep your brass valves working for as long as possible.
Media Flowing Through the Valve
The type of media (substance that flows through the valve) can significantly impact the valve’s lifespan. Abrasive substances, for instance, can cause wear and tear on the valve over time, reducing its lifespan. Similarly, corrosive substances can degrade the valve, leading to leaks or failures.
Consider the nature of the media that will be passing through the valve when choosing one. For example, while brass ball valves stand up to corrosion better than plastic valves, stainless steel valves are better for enduring extremely corrosive substances.
Design and Ability to Replace Components
The valve’s design can also influence its lifespan. For example, some brass ball valves feature a three-piece design that allows for the replacement of seals. This means that instead of having to replace the entire valve when a seal fails, you can simply replace the seal itself. This design feature can significantly extend the lifespan of the valve.
The standard material for seals in brass ball valves is PTFE (polytetrafluoroethylene, the substance commonly known as Teflon). However, if you need more protection against corrosives or abrasives, consider custom ordering RPTFE (the “R” stands for “reinforced.”)
Actuation vs. Manual Operation
The method of actuation, or how the valve is operated, can also affect its lifespan. Nonmanual valves use actuators (devices that open and close the valve), which can be pneumatic, electric, or hydraulic. The choice of actuator can affect the valve’s performance and longevity.
Pneumatic actuators, for example, tend to be reliable and have a long lifespan, but they may not be suitable for all applications. Electric actuators, on the other hand, offer precise control but may require more maintenance. Finally, hydraulic actuators are powerful and can handle high pressures, but they can be more complex and expensive to maintain. Whatever its type, the actuator is likely to outlast the valve it controls.
Temperature and Pressure
Finally, temperature and pressure conditions are factors that can significantly affect a brass ball valve’s lifespan. High temperatures can cause the valve to degrade more quickly, while high pressures can put stress on the piece, leading to potential failures. Choose a brass ball valve rated for the temperature and pressure conditions in which it will be operating.
For high temperature and pressure situations, stainless or carbon steel valves, while more expensive, may be better alternatives due to their distinct seat and sealant materials.
Brass ball valves work well in low-pressure, lower-temperature applications. You can use them for water pipes if they are lead-free certified or in HVAC systems and some oil and gas applications. With proper care and maintenance, brass ball valves should last for years.
