Tips: Flanged diaphragm valve advantages

Flanged diaphragm valves offer several advantages in various industrial applications. Their design features a flexible diaphragm that acts as a barrier between the process fluid and the valve components, providing numerous benefits:

Exceptional Sealing: Diaphragms ensure a tight and reliable seal, preventing leakage and cross-contamination. This is particularly important in industries where purity and sterility are critical, such as pharmaceuticals or food production.
Corrosion Resistance: Diaphragm valves can be made from materials that are highly resistant to corrosion, making them suitable for handling aggressive chemicals and corrosive fluids.
Minimal Maintenance: Their simple construction minimizes the need for maintenance, resulting in reduced downtime and cost savings.
Precise Flow Control: Diaphragm valves offer excellent throttling capabilities, allowing for precise control over flow rates, making them ideal for applications requiring accurate dosing or control.
Biocompatibility: In the medical and biotech industries, these valves are suitable for handling sensitive or biocompatible fluids due to their diaphragm materials.
Reduced Fouling: The smooth, obstruction-free flow path minimizes the risk of fouling and clogging, ensuring consistent performance.
Versatility: Flanged connections make installation and integration into existing systems straightforward.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
