It is commonly used in Yamada NDP-20 and NDP-25 series pumps where precise air switching is required for continuous fluid transfer operation. Maintenance teams, OEMs, and integrators purchase this assembly for replacement of worn air valve components, preventative maintenance, and restoration of proper pump cycling and efficiency.\u003c\/p\u003e\n\u003ch3 data-section-id=\"plkbhx\" data-start=\"522\" data-end=\"541\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"542\" data-end=\"945\"\u003eThe Yamada 802809 air valve assembly is used in industrial fluid handling environments where AODD pumps operate under continuous duty. It is commonly deployed in chemical processing, wastewater treatment, coatings, and fluid transfer systems where controlled air distribution ensures consistent diaphragm movement, stable flow output, and reduced system downtime.\u003c\/p\u003e\n\u003ch3 data-section-id=\"68ulmp\" data-start=\"947\" data-end=\"978\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"979\" data-end=\"1792\"\u003e• Manufacturer: Yamada Corporation\u003cbr data-start=\"1013\" data-end=\"1016\"\u003e• Part Number: 802809\u003cbr data-start=\"1037\" data-end=\"1040\"\u003e• Product Type: Air valve assembly\u003cbr data-start=\"1074\" data-end=\"1077\"\u003e• Function: Controls pneumatic air distribution for diaphragm actuation\u003cbr data-start=\"1148\" data-end=\"1151\"\u003e• Application: AODD diaphragm pumps (NDP-20 \/ NDP-25 series) \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cbr data-start=\"1249\" data-end=\"1252\"\u003e• Operation: Pneumatic air shifting valve system\u003cbr data-start=\"1300\" data-end=\"1303\"\u003e• Components Included: Valve body, spool assembly, seals, gaskets, internal hardware \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cbr data-start=\"1425\" data-end=\"1428\"\u003e• Installation: Internal air valve section of pump\u003cbr data-start=\"1478\" data-end=\"1481\"\u003e• Material: Polypropylene (PP) or aluminum variants available \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cbr data-start=\"1580\" data-end=\"1583\"\u003e• Role in System: Drives alternating diaphragm motion for fluid pumping\u003cbr data-start=\"1654\" data-end=\"1657\"\u003e• Compatibility: Yamada diaphragm pump systems\u003cbr data-start=\"1703\" data-end=\"1706\"\u003e• Duty Cycle: Continuous operation component\u003cbr data-start=\"1750\" data-end=\"1753\"\u003e• Status: Active OEM replacement part\u003c\/p\u003e\n\u003ch3 data-section-id=\"1ln9bp8\" data-start=\"1794\" data-end=\"1820\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1821\" data-end=\"1925\"\u003e• Yamada 804608 air valve assembly\u003cbr data-start=\"1855\" data-end=\"1858\"\u003e• Yamada 802362 air valve assembly\u003cbr data-start=\"1892\" data-end=\"1895\"\u003e• Yamada air valve repair kits\u003c\/p\u003e","brand":"Yamada","offers":[{"title":"New","offer_id":51733867135278,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d019b72f-adff-4193-89b4-ba218ed113c9.jpg?v=1770604013","url":"https:\/\/plgautomation.com\/products\/yamada-802809-air-valve-assembly-802809","provider":"PLG Automation ","version":"1.0","type":"link"}
