If you’re in the business of oxyfuel cutting, heating, or welding, gas control devices are essential to your operation.

With a constant speed feed pump, the lower feedwater flow along with the drop in system head requires the control valve to absorb the additional pressure drop and, as a result, the control valve ...

Referring to the temperature control example in Figure 1, the steam inlet pressure is usually constant. Therefore, the pressure differential (Δp) across the valve is also almost constant, and the ...

A gas regulator may seem like a simple tool, but its role in maintaining safety and efficiency in gas-powered systems is essential. In this video, we’ll break down how a gas regulator works, ...

At this point, the ORIT will begin to open and allow refrigerant to flow into the receiver. Pressure regulating valves can control either upstream pressure or downstream pressure, but not both. When ...

When throttle pressure is constant ... steam flow and thus an increased boiler firing rate. However, because of process latencies, nonlinearities, and interaction, a control system that uses ...

Choked flow in control valves is a subject of serious concern ... By Bernoulli’s law, the total energy at every point in the flow stream is constant, so if velocity is increased, pressure must fall.

Most pumps control the flow of air through the pump using a “constant flow” control mechanism. As back-pressure increases, the pump detects the change and alters the flow accordingly.

A few solutions were attempted, including manual flow-control valves and electronically-controlled pressure regulators, all with limited success. To solve the problem, they contacted the Wilson ...

Consider the steady, flow of a constant density fluid in a converging ... One-dimensional duct showing control volume. When streamlines are parallel the pressure is constant across them, except for ...
