FAQ

How does a manual diaphragm valve work?

Manual handle adjusts diaphragm lift/lower to open/close flow; diaphragm isolates fluid from external components, ensuring aseptic sealing.

What are the two types of diaphragm valves?

Weir-type: Fluid flows over a weir (curved barrier).

Straight-through type: Linear flow path with minimal resistance.

What is the function of the diaphragm valve?

Controls sterile fluid on/off while preventing external contamination, maintaining hygiene in critical processes.

What are the disadvantages of a diaphragm valve?

Diaphragm requires periodic replacement; limited to low-to-medium pressure/temp; poor flow adjustment precision.
