Businesses should never compromise on safety, especially when there is a serious risk of injury and loss of life. As a result, it is important to know when to use different solutions, including safety and pressure relief valves. Similarly though, you need to ensure they don’t cause hazards such as dangerously loud noise. You may need equipment like a safety valve silencer to address this.
Key equipment
Pressure can become an issue if it starts to build and exceeds safe limits. In the worst cases, it could cause catastrophic failures such as explosions. Additionally, it could easily damage sensitive, valuable equipment. Safety valves and pressure relief valves can help prevent these problems and protect people. However, they are not interchangeable, even if there are some similarities. You need to know which to use for various applications.
The most important thing to consider is the valves fill unique roles. A safety valve will open to fully release pressure from a system. They are an essential fail-safe to prevent system failure and the damage it will cause. Relief valves are a little different; they open gradually to slow down the pressure increase. The idea is to ensure the system remains within safe limits without having to completely de-pressurise.
Design
If you look at the designs of safety and pressure relief valves you will immediately see the difference. A safety valve cracks when the pressure exceeds a specific limit. When this happens, pressure can reach a lip and interact with a larger surface, applying more force to the disc. In response, the disc will open around 60% of the way. If the pressure continues to build, it will fully open. The opening can result in a very loud noise, so you may need a safety valve silencer.
A relief valve will feature a valve seat with a disc on top. When pressure increases, it begins to lift the disc. This is why the opening varies depending on the amount of pressure.
Types
As you can see, if you need a fail-safe device, you need a safety valve. On the other hand, if you want a device to manage the system and prevent over-pressure, you need a relief valve.
When you decide which product to use, you need to ensure you select the right type. There are three types of safety valve; direct-acting, bellows, and pilot operated. It’s wise to look at each of them and decide which will work best for your scenario. Similarly, you can choose from four different types of relief valves; direct-acting, pilot-operated, remote-controlled, and electric. Again, decide which is most appropriate for each case.

The one thing we can’t stress enough is how important it is to consider noise, especially in industrial facilities. It can easily get loud enough to cause hearing damage if valves need to open to release or manage pressure. This can have a massive impact on people, health services, and the economy.
Ventx is the ideal company to work with if you need to overcome industrial noise. We can provide equipment for different sources, including safety valves, fans, pumps, and more. The best thing about working with us is we design bespoke solutions for each client, ensuring they provide the best possible results.
So, get in touch today if you want to talk to us about designing a safety valve silencer or other products. We can help at any stage, but always recommend thinking about noise and silencers when designing facilities.
