It is a tandem circuit for the bucket priority circuit.\u003cbr\u003e• The oil from the pump enters port F and the maximum pressure is set by the relief valve.\u003cbr\u003eThe oil passes through the bypass circuits of bucket spool (2) and boom spool (1 ), flows from port E to the drain circuit, then passes through the filter and returns to the tank. If the bucket and boom spools are actuated, the oil flows to the bucket and boom cylinders.\u003cbr\u003eHowever, a bucket priority circuit is used, so when the bucket spool is operated, the boom is not actuated even if the boom spool is operated.\u003cbr\u003e• Two safety valves (with suction) (4) are installed to protect the circuit if abnormal pressure is generated in the bucket circuit. The two safety valves have two functions: acting as relief valves and acting as suction valves to compensate for lack of oil.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53602109325643,"sku":null,"price":58.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-18_bd11b7c0-3f2f-4538-af3c-7c4d33ab0c0c.png?v=1760447934","url":"https:\/\/manualbull.com\/products\/komatsu-wa120-3-wa120-3cs-wheel-loader-service-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
