Backpressure Variable Transducer (BVT)
This remotely mounted regulator modulates the vacuum signal to the EGR valve. It is one of the components in the BVT EGR valve system. It uses 2 backpressure inputs to control vacuum supply to the EGR valve. One input is from the EGR valve control chamber, the other is downstream from the flow control orifice.
