What does the double seated balance valve allow in terms of fluid passage?

The double seated balance valve is designed to provide enhanced fluid flow capabilities compared to other types of valves, particularly single port valves. By having two seats and two different fluid paths, this type of valve can manage the flow more efficiently and effectively. This dual seating mechanism allows it to accommodate higher flow rates and pressures, making it suitable for applications where increased fluid passage is necessary.

When comparing it to a single port valve, a double seated balance valve can indeed pass a greater volume of fluid, potentially up to twice as much. This is because the fluid can flow through both seats simultaneously, effectively doubling the available passage area for the fluid, which is especially beneficial in systems that require a robust and controllable flow of fluids.

In scenarios where fluid flow needs to be maximized, using a double seated balance valve is advantageous due to its design, promoting superior performance in fluid handling systems.
