Let's have a look at how variable valve timing (VVT) works. For a lot of you this is review, but if we want a new generation of car enthusiasts to care about cars, it can't hurt to explain how ...

vpdd = Δp (qmax) Δp (qmin) where: vpdd=valve pressure drop decay Δp (qmax)=valve pressure drop at maximun flow Δp (qmin)=valve pressure drop at minimun flow Using the vpdd calculation, the control ...

How Flow Control Valves Work Flow control valves have a valve stem that moves up or down inside the valve body, causing the needle, or sealing element at the end of the stem, to restrict the flow of ...

August 2021 Choked Flow in Control Valves Choked Flow in Control Valves By Katherine Bartels, Adam Harmon Summary Choked flow in control valves is a subject of serious concern for industrial users.

1. Flow-to-open cutaway. Control valves equipped with noise-abatement trim, such as a drilled-hole cage or a tortuous path stack, are typically oriented in the flow-to-open direction.

Before we get to the Live Valve, let's take a quick look at how the internal bypass works. Seen here is the 2021 Ford F-150 Raptor's shock piston at normal ride height.

1. Here’s a simple schematic illustrating how the 1967-1978 Mustang climate control vacuum system works. We’re using the engine’s intake manifold vacuum (suction) to do our work for us.
