Yamada 773174 PTFE AODD Diaphragm Pump Ball Valve

Description:

The Yamada 773174 is a PTFE valve ball used in air-operated double diaphragm (AODD) pump systems to regulate fluid flow and ensure proper sealing during pump operation. It is commonly used in Yamada NDP-80 series diaphragm pumps where large-volume fluid transfer and consistent check valve performance are required. Maintenance teams, OEMs, and integrators purchase this component for replacement of worn valve balls, preventative maintenance, and restoring pump efficiency and flow reliability.

Applications:

The Yamada 773174 PTFE ball is used in industrial fluid handling environments where reliable check valve operation is critical. It is commonly deployed in AODD pumps used for chemical processing, wastewater treatment, coatings, and bulk fluid transfer systems where corrosion resistance and consistent sealing are required to maintain proper pump cycling and system performance.
