Float Valves are a type of valve that uses a float to regulate the level of fluid in a tank or container. The float, typically a hollow ball or similar object, rises and falls with the fluid level, controlling the valve to maintain the desired level.
Working Mechanism:
- Float Action: As the level of the fluid rises in the tank, so does the float. As the float rises to a set level, it triggers the valve to close, stopping the inflow of more fluid. When the float drops, it triggers the valve to open, allowing more fluid to flow in.
- Automatic Regulation: A major advantage of a float valve is its automatic operation. It continuously adjusts the inflow of the fluid based on the fluid level, without needing manual intervention or complex control systems.
In addition to these, some float valves feature a unique N.M.M.P (No Moving Mechanical Parts) design. This design includes a reinforced sleeve that forms a drip-tight seal with a corrosion-resistant core, offering additional advantages:
- Instantaneous, Smooth Opening: Upon removal of control pressure, the valve opens instantly yet smoothly, preventing any water hammer effect in the piping system.
- Resistance to False Operation: The N.M.M.P design prevents false operation due to transient surges in fluid supply pressure.
- Durable and Low Maintenance: With the reinforced sleeve as the only moving part, the N.M.M.P design minimizes wear and tear, prolonging its lifespan and reducing maintenance requirements.
Application features:
- Fluid Level Regulation: Float valves are typically used in applications where it’s crucial to maintain a certain level of fluid in a tank or container.
- Automatic Operation: The automatic operation of float valves reduces the need for manual monitoring and intervention, saving time and resources.
- Versatile Use: They can be used with a wide variety of fluids, including water, brackish water, or seawater, making them suitable for industries such as chemical, petrochemical, and offshore platforms.
- Foam/Water Systems: Some float valves can also serve as a control valve in foam/water systems, highlighting their versatility.
- Range of Sizes and Fittings: Float valves come in a variety of sizes and with different inlet and outlet fittings, allowing for adaptability in various piping configurations.
- Durability and Low Maintenance (for N.M.M.P design): The N.M.M.P design makes these particular float valves more durable and requires less maintenance, which can result in cost savings over time.
