The pressure of the oil flowing to the pilot valve is regulated by the pilot reducing valve, and actuates the directional and range spools as the solenoid valves are switched ON or OFF.\u003cbr\u003eWhen the directional and range spools are switched, the oil, whose pressure is regulated by the electronic control modulation valve, is supplied to the selected clutch to provide the necessary speed range.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53602123120971,"sku":null,"price":58.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-74.jpg?v=1760447995","url":"https:\/\/manualbull.com\/products\/komatsu-wa450-3-wa450-3ll-wheel-loader-service-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
