Used Truck Valves, EGR Valves & Engine Control Parts

Used truck Valves

Valves are critical parts of a modern truck engine and emissions control system. On heavy commercial vehicles they may control exhaust gas flow, regulate boost pressure, direct cooled EGR gases, support engine management operation or form part of a larger manifold and pipework assembly. In this Valves category, the focus is on used OEM engine-related valve components for lorries, HGVs and commercial vehicles, particularly parts fitted around the EGR and exhaust gas control system.

VRA Truckparts lists genuine used Valves removed from dismantled donor trucks, with stock changing as vehicles are broken for parts. Current examples include MAN EGR valve assemblies, MAN boost pressure control and EGR exhaust control valves, EGR valve base plates and EGR cooler or exhaust gas transfer pipes. Listings may show OEM and casting references such as 51081506095, 51081506129, 51081506143, KS560124-48, 5846R232, 51259020131, 51.25902.0131, 51057013030, 51.05701-3030, 51081403045 and 51.08140-3045 where these are visible or confirmed. Because valve assemblies can look similar across MAN TGL, TGM, TGS, TGX and TGA models, every buyer should check the individual listing carefully before ordering.

What you will find in the Valves category

The Valves category may include complete valve units and related engine valve hardware, depending on the donor vehicles currently being dismantled. These are usually used OEM parts rather than universal aftermarket items, so identification by part number and physical layout is essential.

• Used MAN EGR valve assemblies for TGL, TGM, TGS and TGX Euro 5 or Euro 6 applications when available.
• Boost pressure control valve and EGR exhaust control valve assemblies, including units listed with references such as 51259020131 and 51.25902.0131.
• EGR cooler pipes and exhaust gas transfer pipes, including MAN TGA, TGS and TGX style pipework with flange-mounted OEM markings.
• EGR valve base plates, support brackets and cast mounting plates used around the valve and exhaust gas routing assembly.
• Valve housings, cast iron manifold sections, stainless pipework and linked components supplied as shown in the product photos.
• Used OEM parts with visible casting numbers, flange numbers, manufacturer marks or alternative references where available.
• Related fixings, brackets, actuator sections or pipe connections only where they are present on the part being sold.

Truck brands & typical applications

The current product examples in this Valves section are strongly focused on MAN commercial vehicles. Typical applications may include MAN TGA, TGL, TGM, TGS and TGX trucks, especially Euro 5 and Euro 6 engine platforms, but compatibility must never be assumed from the model name alone. A MAN TGX EGR valve, for example, may differ by engine code, emissions standard, valve body casting, actuator type, pipe orientation or OEM number.

• MAN TGL and TGM: may use compact EGR valve assemblies and engine control components depending on engine variant.
• MAN TGS and TGX: common applications for EGR valves, boost pressure control valves, cooler pipes and support plates.
• MAN TGA: some EGR cooler pipe and exhaust transfer pipe components may appear depending on donor stock.
• Euro 5 and Euro 6 engines: valve layout and emissions hardware can vary significantly between standards.
• Fleet and workshop use: used OEM Valves can help keep vehicles working when the old part is damaged, blocked or no longer serviceable.

Why Valves matter

Correctly working Valves help the truck engine breathe, control exhaust gas recirculation and maintain the expected relationship between air, boost pressure, combustion temperature and emissions control. An EGR valve that sticks open, sticks shut or fails to seal properly can affect drivability, fault codes, fuel consumption, smoke levels and engine protection strategies. Likewise, a damaged EGR cooler pipe or base plate can cause leaks, incorrect gas flow, exhaust noise or problems around adjacent sensors and pipework.

On Euro 5 and Euro 6 HGVs, valve assemblies are often integrated into a wider emissions system. The part may connect to the EGR cooler, exhaust manifold, intake side, boost control system and electronic engine management. A small mismatch in flange position, pipe connection angle, plug type or actuator arrangement can stop a part fitting correctly. That is why used OEM Valves should be chosen by reference number and visual comparison, not just by the truck badge or a broad model description.

Typical reasons to replace Valves

Commercial vehicle Valves operate in hot, dirty and vibration-heavy conditions. EGR and exhaust gas control parts in particular are exposed to soot, thermal cycling and corrosion. Replacement may be required because the part has failed, because it was damaged during repair work, or because a complete engine assembly is being rebuilt with the correct original equipment components.

• Internal sticking, poor movement or carbon build-up inside an EGR valve assembly.
• Cracked cast housings, broken flanges or damaged mounting points around the valve body.
• Exhaust gas leaks from worn faces, distorted pipe connections or corroded EGR cooler pipe sections.
• Damaged actuator housing, electrical plug, sensor connection or control valve section.
• Missing brackets, base plates or support hardware after previous repairs or engine removal.
• Incorrect aftermarket or incompatible replacement part fitted to the truck.
• Visible impact damage, seized bolts, stripped threads or excessive corrosion on the original unit.

How to choose the correct Valves

Before buying used truck Valves, treat the part as a technical fitment item. Many valve assemblies are specific to engine family, emissions level and installation layout. A part that looks close in a small photo may still differ in the casting number, pipe outlet, actuator position or bolt pattern.

• Check the truck make, model and exact generation, such as MAN TGL, TGM, TGS, TGX or TGA.
• Confirm engine type, engine code and Euro/emission standard, especially for Euro 5 and Euro 6 systems.
• Match the OEM number and alternative references, for example 51081506095, 51081506129, 51081506143, 51259020131 or 51057013030 where relevant.
• Compare casting numbers, stamped flange numbers and supplier references such as KS560124-48 or 5846R232 if shown.
• Look closely at electrical plug shape, actuator position, sensor location and any vacuum or pressure connections.
• Compare flange shape, gasket face, bolt hole pattern, pipe angle and mounting bracket layout.
• Check whether the listing includes only the valve, a base plate, pipework, manifold section or a wider assembly.
• Use the listing photos to compare your old part from several angles before placing an order.

If you are unsure which Valves will suit your truck, use how to find the right truck part and compatibility and VIN checks before ordering. The safest approach is to compare the old part number, VIN or registration details, engine specification and clear photos of your existing valve assembly with the listing information.

Used OEM parts from dismantled trucks

VRA Truckparts supplies used genuine OEM truck components removed from donor vehicles. Valve-related parts are photographed and listed with visible details such as OEM numbers, casting marks, manufacturer references, included fittings and general condition notes where available. Used condition can include normal commercial vehicle marks, surface corrosion, heat staining, soot residue or signs of previous service life, especially on EGR and exhaust gas components.

Each listing should be read on its own merits. Some assemblies may have been checked for basic operation before dismantling if stated in the product text, but this should not be assumed across all Valves. Buyers should review the photos, part numbers and condition description carefully and ask for support if a reference number is unclear. You can also read more about our dismantling and quality process to understand how used truck parts are removed, handled and prepared for resale.

Related categories

Valves sit within the Engines & Components area of lorry and truck parts, so buyers often check connected systems at the same time. Depending on the fault, you may also need related EGR pipework, engine brackets, sensors, cooling parts, manifolds or other engine-mounted assemblies. Current stock changes regularly as different donor trucks are dismantled, so related items may appear elsewhere in the engine parts range.

For technical matching, the most useful internal resources are trucks we dismantle, how to find the right truck part and compatibility and VIN checks. These pages are useful when comparing MAN TGX, TGS, TGM, TGL and TGA parts by VIN, registration, OEM number or visual layout.

Delivery, payment & returns

Once the correct Valves have been identified, check the product listing for the exact item condition, included components and any part references shown. For order information, see delivery and shipping, payment and VAT information, warranty and part condition and returns and refunds. VRA Truckparts supplies used genuine OEM truck parts to trade and private buyers, but compatibility remains the buyer’s responsibility unless the part has been specifically checked against the information supplied before purchase.
