n A-Type Screwed Diaphragm Valve uses a flexible diaphragm to control the flow of media through the valve. Turning the handwheel raises or lowers the diaphragm, allowing the valve to open, regulate flow or provide positive shut-off.

The diaphragm forms a barrier between the process media and the valve’s operating components. This helps protect the working mechanism from the media and reduces potential leakage paths.

The pictured model features manual handwheel operation and female screwed/threaded end connections, providing a compact alternative to larger flanged diaphragm valves and making it particularly useful in smaller-bore piping installations.
