Considerations When Buying Pressure Vacuum Valves and Butterfly Valves

 

Pressure vacuum valve (PVVs) and butterfly valve are vital components in industrial systems that handle fluids and gases. PVVs regulate pressure differentials, protecting storage tanks from damage caused by excessive pressure or vacuum conditions. On the other hand, butterfly valves control flow by providing a tight shut-off and allowing precise control over fluid or gas passage. When it comes to purchasing these valves, it is crucial to consider several factors to ensure optimal performance, safety, and compatibility with your specific application.

When buying pressure vacuum valve, you should consider pressure and vacuum ratings. Select PVVs with appropriate pressure and vacuum ratings that match the requirements of your system. Consider factors such as maximum allowable working pressure (MAWP) and the desired vacuum pressure level. Ensure the selected valves can handle the highest pressure and vacuum conditions that may be encountered.

You should also consider material compatibility. PVVs come in various materials such as stainless steel, aluminum, brass, or thermoplastics. Consider the compatibility of the valve material with the fluid or gas being handled, taking into account corrosive properties, temperature variations, and other environmental factors. Ensure the materials used are resistant to corrosion, erosion, and degradation.

When it comes to buying butterfly valves, you should pay attention to valve type. There are different types of butterfly valves, including resilient-seated, high-performance, and triple-offset valves. Each type has specific advantages and limitations. Understand the requirements of your application and choose the appropriate valve type that provides the desired performance and reliability.

Size and pressure rating are also important things to consider to ensure compatibility with your system. Proper sizing and pressure rating are crucial for efficient flow control and to prevent issues such as pressure drops or leakage.

You should also consider disc material and seat design. Evaluate the material used for the valve disc and seat. Common materials include stainless steel, cast iron, or thermoplastics. The disc material should be resistant to corrosion and erosion, and the seat design should provide a tight shut-off to minimize leakage.
