Product Description

Samco Black finish DV/BOV. 

Single Piston (DV)Re-Circulating Valve, with 25mm Inlet & Exhaust Ports, replacement valve for Plastic OEM Valve. SamcoSport fitting kit may be required to fit this Valve.(non VAG applications)

This valve can also be used as a BOV by simply not connecting any recirculating plumbing back into the intake pipe. 

Compared to stock valves, Performance DV valves release more air, faster and piston type valves do not fail like the weaker diaphram type factory versions all while offering the ability to hold higher boost levels. 

-Stealth Black 

-25mm Piston type valve 

-Includes 3 springs for various levels of boost

-Includes a Samco Hose Keychain & Sticker


*FAQ (from Samco engineers)

The spring rates are in three pressures, the stock silver spring which comes in the valve is the same pressure as the stock VW/Audi plastic valve, the white spring lifts at 7~8 Psi and the red spring around 9~10 psi. There is however a misconception that the spring pressure is solely responsible for controlling the piston on the seat when the boost pressure is trapped in the inlet track, but these are more of an aid to keep the piston/ diaphragm in a linear motion on the spring with some benefit at base idle.

 The vacuum signal tube also helps control both vacuum and boost while the valve is operational and under load, the spring is then controlled more by these factors so a good seal would be more critical hence Samco's development of the "U-Tech" seal which work far better than our competitors general "O" ring approach.





direct replacement for 1.8T & 2.7T factory DV's & many Porsche models
