Steriflow sanitary diaphragm valves provide precise, hygienic fluid control with full traceability and regulatory compliance, ensuring reliable, contamination-free operation in critical processes.
How do Sanitary Diaphragm Valves Work?
Sanitary diaphragm valves regulate fluid flow using a flexible diaphragm. When the diaphragm is pressed against the valve seat, it forms a secure seal that stops fluid movement in both directions.
Key Applications of Hygienic Diaphragm Valves
Our hygienic diaphragm valves are used in the Food & Beverage, Pharmaceutical & Biotechnology, and Personal Care & Cosmetics industries for applications including:
General Use
- Single-valve weir design for manual on/off or air-actuated flow control in drug additives, drug products, and clean utility systems.
Upstream Processing
- Bioreactors/Fermenters: Regulation of WFI (Water for Injection), growth media, intermediate drug products, clean dry air and gases, clean steam, and other clean utility fluids.
- Perfused Bioreactors: Precise control of retentate or permeate fluid flow.
Downstream Processing
- Control of WFI, buffers, solvents, intermediates, and finished drug products, along with clean dry air, gas, steam, and utility fluids in processes such as:
- Separation
- Filtration
- Chromatography
- Formulation
- Fill-finish operations
Buffer & Media Preparation
- Flow regulation of WFI, buffers, growth media, clean steam, and other clean utility fluids.
