It is manufactured to the original Volvo Penta dimensions and interface requirements so calibrated oil flow and pressure are maintained through the lubricating circuit. Brown-coded reduction valve. In service, it reduces and regulates oil pressure within the oil-filter housing circuit to protect downstream components. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1547368 against the installed assembly before ordering.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cp\u003e\n Typically suits:\n\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta TWD740GE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TWD740VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TD640VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD740GE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD741GE\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  TWD, TD, TAD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  OEM Volvo Penta part number 1547368\n \u003c\/li\u003e\n \u003cli\u003e\n  Brown colour-coded variant - colour identifies the correct pressure specification\n \u003c\/li\u003e\n \u003cli\u003e\n  System group: Lubricating and Oil System\n \u003c\/li\u003e\n \u003cli\u003e\n  Net weight: 0.068 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits TD640, TWD740 and TAD740\/741 series diesel engines\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n The reduction valve limits and stabilises oil pressure in the lubrication circuit, bleeding off excess pressure so oil is delivered to bearings and galleries at the correct working value. This protects the oil pump, filter and internal engine components from over-pressure during cold starts and high engine speeds.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Low or erratic oil pressure readings at the gauge or warning lamp\n \u003c\/li\u003e\n \u003cli\u003e\n  Excessively high oil pressure, particularly when cold, indicating a stuck-closed valve\n \u003c\/li\u003e\n \u003cli\u003e\n  Oil leakage or weeping around the valve seat or housing\n \u003c\/li\u003e\n \u003cli\u003e\n  Noisy valve operation or pressure fluctuation at steady engine speed\n \u003c\/li\u003e\n \u003cli\u003e\n  Debris, varnish or wear on the valve plunger and seat preventing proper sealing\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  This is the Brown-coded valve in a range where colour denotes the pressure setting - never fit a differently coloured valve even if the weight looks close, since colour is the only reliable spec identifier here\n \u003c\/li\u003e\n \u003cli\u003e\n  Rule out a worn pump, blocked strainer or faulty gauge\/sender with a mechanical pressure check before condemning this valve - several other faults can mimic a bad reduction-valve reading\n \u003c\/li\u003e\n \u003cli\u003e\n  While it's out, check the bore is clean and confirm the plunger drops freely under its own weight - debris is the common cause of one sticking\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta part\n \u003c\/li\u003e\n \u003cli\u003e\n  Brand new\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied in original or equivalent packaging\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53380773216548,"sku":"9582540","price":96.91,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_2df72c43-e150-4c8b-9eca-15d897ca1e4c.jpg?v=1788055983","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/1547368-reduction-valve-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
