Brandoni Diaphragm Control Valves are used to regulate and shut off the flow of fluids—especially aggressive, abrasive, or high-purity media—in chemical processing, water treatment, and hygienic systems.

A flexible diaphragm is pressed down onto a seat to stop flow or lifted to allow it. The diaphragm isolates the working parts of the valve from the fluid, ensuring clean operation and preventing contamination.

Diaphragm valves offer leak-tight sealing, chemical resistance, and full isolation between the fluid and moving parts, making them ideal for corrosive or sterile applications.

They are used in water treatment, chemical dosing, pharmaceuticals, food & beverage processing, and any system requiring clean or corrosion-resistant flow control.

Brandoni offers diaphragms in materials such as EPDM, PTFE, and other chemically resistant compounds, depending on the application and media being handled.

Brandoni diaphragm valves are available in materials like cast iron, PVC, and polypropylene, offering flexibility across chemical and hygienic environments.

Yes, especially models like the Series 12.0 and Series 13.0 are designed for accurate manual flow modulation as well as shut-off functionality.

Yes, depending on the diaphragm and body material selected. PTFE diaphragms, for example, offer higher temperature resistance than standard rubber options.

The Series 12.0 is a standard diaphragm control valve with compact design, while the Series 13.0 includes an extended bonnet for improved modulation and thermal separation in more demanding conditions.

Some models may be WRAS approved for use in potable water applications. Always check the specific certification of the model before use.

While diaphragm valves are primarily manually operated, certain configurations can be adapted for actuation depending on the system requirements.

These valves are low maintenance, but periodic inspection of the diaphragm and sealing areas is recommended. Diaphragms are replaceable and easy to service.
