Everything you need to know to get a basic understanding of heart sounds. I cover S1, S2, S3, and S4, what leads to those sounds as well as Systolic and Diastolic murmurs.

Pressure relief valves serve a major role in maintaining the safety and stability of oil and gas valve systems. These relief valves help control the pressure in oil and gas systems which can pose harmful threats to equipment, that if...

Control valves regulate flow, pressure, temperature and liquid levels. These regulations are maintained through a process of partially or fully opening and closing valves. These control valves receive signals from controllers...

An overview of what programming functions are and how they work.

Diaphragm valves use an elastomeric diaphragm to separate the flow stream from the closure element. Diaphragm valves are a great choice for controlling the flow of fluids, containing suspended solids, and offer the...

Butterfly valves are quick opening, quarter turn valves. Butterfly valves regulate or isolates flow in a manner very similar to that of a ball valve, but they are usually less expensive and lighter in weight, giving these...

standard test measure following NISTIR 7383, SOP 18. The methodology is also appropriate for field standard test measure calibrations following NISTIR 7383 SOP 19.

A check valve is a valve that normally allows fluid to flow through it, and only in one direction. Check valves are two-port valves, meaning they have a port for inlet, and a port that acts as an outlet. Various types of...

Video tutorial helping students identify heart chambers, valves and vessels using illustrations and radiographs. Additionally, each of their functions is covered.

In this video, we discuss another type of pressure-volume loop in detail that you may encounter in your anatomy and physiology class.

In this video, the teacher explains how to decode unfamiliar words by breaking them up into syllables. They discuss the differences between long and short vowel sounds and emphasize the importance of identifying the vowels in a word. By...

Plug valves have a very simple design. Plug valves only consist of three components—the body, cover, and plug. In this simple and fast course by CTE Skills, you will begin to master and understand plug valves and their...
