FAQ
How does a manual diaphragm valve work?
Manual operation (e.g., handle) lifts/lowers the diaphragm to open/close the flow path; the diaphragm isolates fluid from external components, ensuring aseptic sealing.
What are the disadvantages of a diaphragm valve?
Diaphragm requires regular replacement due to wear; not ideal for long-term high-pressure/high-temperature use; limited flow control precision.
What are the two types of diaphragm valves?
Mainly weir-type (fluid flows over a weir) and straight-through type (linear flow path), distinguished by internal structure and flow direction.
What is the alternative to a diaphragm valve?
Ball valves or gate valves, preferred for non-aseptic, high-pressure, or high-flow applications due to better durability and flow efficiency.
