⚙️ How It Works
The valve consists of three core parts: the actuator, stem, and floating ball, all housed within a robust one-piece body. As the actuator turns, it moves the stem, which rotates the ball, opening or closing the flow. Elastomeric seats with seal rings ensure a leak-proof seal, even under fluctuating pressure conditions.
🌍 Applications
| Application | Function |
|---|---|
| Water Tanks / Storage Systems | Automatically controls inflow based on tank levels, preventing overflow. |
| Fuel & Gas Lines | Ensures uncontaminated flow with impervious seals. |
| SIL 3 Emergency Systems | Ideal for rapid-response shut-off in safety-instrumented environments. |
| Pressure Relief Systems | Activates at critical pressure levels to prevent line failure. |
