Product type
A pressure relief valve is a safety device designed to protect pressurized equipment and systems from exceeding their maximum allowable pressure. It automatically releases excess pressure when it reaches a predetermined level, ensuring safe operation and preventing potential failures or explosions. These valves are typically made of durable materials such as stainless steel, brass, or plastic, depending on the application and media being handled.
| Material | Stainless steel, brass, or plastic |
| Pressure range | Up to 10,000 psi |
| Temperature range | -40°F to 400°F |
| Connection types | Threaded, flanged, or welded |
| Size range | 1/4 inch to 6 inches |
| Set pressure accuracy | ±5% of set pressure |
When selecting a pressure relief valve, consider the maximum pressure and temperature of your system to ensure compatibility. Specify the required set pressure, as well as the material based on the media being handled. Certifications such as ASME or API may be important depending on industry standards. Additionally, provide information on the connection type and size needed for installation, as well as the quantity required for your application.
