roper sizing of diaphragm valves is crucial for maintaining efficiency and longevity. Weir’s advanced weir diaphragm sizing methodology takes into account factors such as flow rate, pressure, and media compatibility, ensuring precise valve operation. This approach is especially vital in straightthrough diaphragm valves, where minimal pressure drop is essential.
Our weir diaphragm sizing technology offers several advantages:
Straightthrough diaphragm valves are designed for applications where unrestricted flow is critical. Weir’s valves maintain a full port design, minimizing turbulence and ensuring smooth fluid passage. This design is particularly effective in pneumatic diaphragm valves, where rapid actuation is required.
Our straightthrough diaphragm valves come with:
neumatic diaphragm valves are favored for their responsiveness and reliability. Weir’s integration of pneumatic diaphragm valves in our product lineup has set a new standard in fluid control. These valves are particularly useful in applications requiring frequent cycling and high precision.

Our pneumatic diaphragm valves stand out due to:
Weir’s weir diaphragm sizing and straightthrough diaphragm valves are versatile, making them suitable for industries such as:
In a recent project this year, our pneumatic diaphragm valves were implemented in a water treatment plant. The precise weir diaphragm sizing ensured minimal pressure loss, while the straightthrough design maintained consistent flow rates, improving overall system efficiency.
