21997096 Valve | Genuine Volvo Penta Part

🔧 Product Description

EGR control valve for TAD870VE-TAD873VE engines. It meters cooled exhaust gas according to ECU command and must match the engine's emissions calibration and connector configuration.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD870-73VE

• Engine Family: TAD

⚙️ Key Features

• Application-specific flow and sealing characteristics
• Designed for the original actuator and connection interfaces
• Materials selected for exhaust gas, air, coolant or fuel exposure
• Control calibration must match the engine

🔌 Function

Controls, isolates or meters flow in the assigned engine system under command from the mechanical or electronic control arrangement.

⚠️ Common Signs of Failure

• Sticking open or closed
• Internal or external leakage
• Engine derate or fault codes
• Poor response to actuator command
• Carbon, corrosion or debris preventing sealing

🛠️ Service Notes

• Work clean — a valve is a precision component, and dirt or swarf carried in on the sealing faces is the commonest reason a new one fails early
• Fit new sealing rings, gaskets or washers wherever the original used them rather than reusing the old ones, and lubricate them lightly so they seat without rolling or nipping
• Check the seat, bore or housing the valve fits into for corrosion, scoring or distortion; a valve only seals as well as the face it beds on
• Tighten fixings and threaded connections to the figures and in the order given in the workshop manual for your engine — a valve body is easily distorted by overtightening
• After fitting, bleed or refill the system as required, then run the engine and check the valve for leaks and for correct operation before the boat is used
