Characterized ball valves provide enhanced flow control along with several additional advantages compared to globe valves. Globe valves have long been the standard for many commercial and industrial ...

Figure 1. Sliding-stem globe and angle control valves. The first distinction among globe and angle valves is whether the valve is post- or cage-guided. In post-guided valves (see Figure 2), the ...

Valve 3 is a 45-degree angle with a 30-degree back cut, while valve 4 is a 30-degree seat angle with a very shallow, 22-degree back cut. Flow testing revealed that valve 4 generated the most low ...

For example, if it’s essential to provide a full pipe opening when the valve is open, the pinch valve designs (see A, Figure 1 below), the full-opening angle valves (B), some of the Saunders valve ...
