Manual three-way diaphragm valve is a valve that controls the opening and closing of the valve core by manually rotating the handwheel or handle to drive the elastic diaphragm up and down. Its core feature is the use of a diaphragm to completely isolate the fluid inside the valve from the driving mechanism, effectively preventing leakage and contamination. This valve has three channel ports, which can flexibly achieve fluid diversion, merging, or flow direction switching, especially suitable for fluid control applications that require no leakage and corrosion resistance. It is commonly used in industries such as chemical, pharmaceutical, and water treatment.
