It is commonly used in Yamada diaphragm pumps such as the NDP-25 series where chemical resistance and reliable check valve operation are required. Maintenance teams, OEMs, and integrators purchase this component for replacement of worn valve balls, preventative maintenance, and restoring pump efficiency and sealing performance.\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=\"938\"\u003eThe Yamada 770691 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 transfer, wastewater processing, coatings, and fluid dosing systems where corrosion resistance and consistent sealing are required for proper pump cycling and flow control.\u003c\/p\u003e\n\u003ch3 data-section-id=\"68ulmp\" data-start=\"940\" data-end=\"971\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"972\" data-end=\"1582\"\u003e• Manufacturer: Yamada Corporation\u003cbr data-start=\"1006\" data-end=\"1009\"\u003e• Part Number: 770691\u003cbr data-start=\"1030\" data-end=\"1033\"\u003e• Product Type: Valve ball \/ check ball\u003cbr data-start=\"1072\" data-end=\"1075\"\u003e• Material: PTFE (Teflon)\u003cbr data-start=\"1100\" data-end=\"1103\"\u003e• Size: ~25T \/ ~35 mm class\u003cbr data-start=\"1130\" data-end=\"1133\"\u003e• Function: Controls flow and sealing in diaphragm pump chambers\u003cbr data-start=\"1197\" data-end=\"1200\" data-is-only-node=\"\"\u003e• Application: AODD diaphragm pumps (e.g., NDP-25 series) \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cbr data-start=\"1295\" data-end=\"1298\"\u003e• Chemical Resistance: High (PTFE suitable for aggressive fluids)\u003cbr data-start=\"1363\" data-end=\"1366\"\u003e• Installation: Internal pump valve assembly\u003cbr data-start=\"1410\" data-end=\"1413\"\u003e• Weight: ~0.048 kg \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cbr data-start=\"1470\" data-end=\"1473\"\u003e• Duty Cycle: Wear component (periodic replacement required)\u003cbr data-start=\"1533\" data-end=\"1536\"\u003e• Status: Active industrial replacement part\u003c\/p\u003e\n\u003ch3 data-section-id=\"1ln9bp8\" data-start=\"1584\" data-end=\"1610\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1611\" data-end=\"1748\"\u003e• Yamada 770693 (larger PTFE ball variant)\u003cbr data-start=\"1653\" data-end=\"1656\"\u003e• Yamada 771524 (smaller PTFE ball variant)\u003cbr data-start=\"1699\" data-end=\"1702\"\u003e• Generic PTFE valve balls (matched size\/spec)\u003c\/p\u003e","brand":"Yamada","offers":[{"title":"New","offer_id":51733869396270,"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_76665fda-c14b-43ca-94b7-d18d628512ee.jpg?v=1770604020","url":"https:\/\/plgautomation.com\/products\/industrial-770691-valve-ball","provider":"PLG Automation ","version":"1.0","type":"link"}
