Gas Approved Valves

Have you ever wondered how the flow of fluids is regulated in different industries? The answer lies in control valves, which play a crucial role in managing the flow and pressure of fluids in different systems.

EN331 Gas-Approved Valves

EN331 is one of the most widely recognized standards for gas-approved valves. This standard requires that valves be tested for functionality and safety in a variety of conditions, such as extreme temperatures and pressures.

Gas-approved valves are used in a variety of applications, such as in gas pipelines and distribution systems. They play a critical role in ensuring the safe and efficient transport of gas.

What Valves are Available to EN331 Standard?

There are several types of valves available to EN331 standard, including ball valves, gate valves, globe valves, and check valves. Each type of valve serves a specific purpose and has unique features.

Ball valves are commonly used in gas installations because they have a quick and easy shut-off mechanism. Gate valves are used when a straight-through flow is required, while globe valves are used when more precise flow control is needed. Check valves are used to prevent backflow and ensure a one-way flow.

When selecting a valve to EN331 standard, it is important to consider the application, the required flow rate, and the pressure rating. In addition, the valve must be installed and maintained properly to ensure it functions safely and effectively.


In conclusion, gas-approved valves are an essential component of any gas system. They ensure the safe and efficient flow of gas, preventing leaks and potential hazards. It’s important to choose the right valve for your specific needs. With the right valve and proper care, you can have peace of mind knowing that your gas system is operating safely and reliably.
