Some of the most common types of valves include: ball (full port, standard port, reduced port), gate, check (including swing check and y-pattern swing check), butterfly, globe, pressure relief and instrumentation. The most commonly used is the gate valve....
Abutterfly valve, illustrated in Below Figure, is a rotary movement valve used for on/off flow control and especially in throttling applications. The flow control element in butterfly valves is a circular disk with its pivot axis at right angles to the direction of flow. A 90° turn of th...
To control flow without contaminating media such as blood, pharmaceuticals or reagents, a wide variety of medical devices and analytical equipment utilize media isolation valves. This article explores the characteristics of three main types of valves commonly used to isolate media. By comparing the adv...
