A stainless steel gate valve is a type of valve used to control the flow of fluids in piping systems. Made primarily from stainless steel, these valves are designed to provide a tight seal and are typically operated by a handwheel or actuator. They are known for their durability and resistance to corrosion, making them suitable for various industrial applications.
| Material | Stainless steel, often grades 304 or 316 |
| Size range | 1/2 inch to 24 inches |
| Pressure rating | Class 150 to Class 2500 |
| Temperature rating | Up to 800°F (427°C) |
| End connections | Flanged, threaded, or weld end |
When selecting a stainless steel gate valve, consider the size, pressure rating, and temperature range required for your application. It's also important to specify the type of end connections needed, such as flanged or threaded. Additionally, inquire about the material grade to ensure compatibility with the fluids being handled. Certifications and compliance with industry standards may also be relevant depending on the application.
