Product type
Pressure relief valves are safety devices designed to control or limit the pressure in a system by releasing excess pressure. They are typically made from materials such as brass, stainless steel, or plastic, depending on the application and the media being handled. These valves operate automatically, opening at a predetermined pressure to prevent system failure or damage.
| Material | Brass, stainless steel, or plastic |
| Pressure range | Up to 300 psi or higher |
| Connection types | Threaded, flanged, or welded |
| Temperature range | Up to 250°F or more |
| Size options | 1/4 inch to 4 inches |
When selecting a pressure relief valve, consider the specific pressure and temperature requirements of your system. It's important to specify the correct set pressure, connection type, and material compatibility with the media. Additionally, inquire about certifications and standards that may be relevant to your industry, such as ASME or API, and determine the quantity needed for your application.
