The Ultimate Guide to Solenoid Valves for Ammonia Gas in 2-Inch Pipes
Solenoid valves play a critical role in various industrial applications, particularly in the refrigeration industry where ammonia is commonly used as a refrigerant. These valves offer precise control over fluid flow, ensuring efficient operation and safety in systems handling ammonia gas. In this guide, we will explore the different types of solenoid valves suitable for ammonia gas in 2-inch pipes, their applications, and key technical features.
Comparison of Solenoid Valves for Ammonia Gas
| Valve Type | Application Area | Body Material | Suitable for Ammonia | Operating Pressure | Temperature Range |
|---|---|---|---|---|---|
| SV2 | Refrigeration Systems | Ductile Iron | Yes | Up to 31 bar | -45 °C to 105 °C |
| SV2A | Commercial Refrigeration | Ductile Iron | Yes | Up to 31 bar | -45 °C to 105 °C |
| S4A2 | Industrial Refrigeration | Stainless Steel | Yes | Up to 40 bar | -50 °C to 120 °C |
| S5A | Large Refrigeration Systems | Ductile Iron | Yes | Up to 34 bar | -45 °C to 110 °C |
How Solenoid Valves Work
Solenoid valves operate using electromagnetic coils that control the movement of a plunger within the valve body. When electrical current flows through the coil, it creates a magnetic field that moves the plunger, either opening or closing the valve. This mechanism allows for quick and efficient control of fluid flow, making solenoid valves ideal for systems requiring rapid response times.
Types of Solenoid Valves for Ammonia Gas
