When a vehicle is started, the control valve acts as a bypass to provide the engine with the necessary air to start and maintain a steady idling speed. Due to the constant flow of air, the valve ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

A new control valve is less vulnerable to damage by high-velocity fluid. Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow ...

OBJECTIVE: Wet flow, pressure excursions ... "pop back" through the air valve. In any case, flow will be established in the intake manifold, beginning at a low flow velocity, rising to a peak ...

Let’s talk about how bore and stroke affect air quantity and velocity. If we look at two engines running at the same rpm, the one with a longer stroke (undersquare) has its piston flying up and down ...

has introduced its new ISD board that is designed to measure air temperature and air flow velocity from two independent sensors. The board can be used to control various devices or to provide read-out ...

Over time, high velocity across ... more significant damage and flow control problems. Courtesy: Conval To try to compensate for the limitations of standard globe valves, some plant operators ...
