Valve types category. Valves are essential components used to control the flow of fluids in several systems. A description of the types of conventional valves used in piping systems is provided here.
The Basics of Globe Valves: What You Need to Know. The term globe valve applies to a valve whose body is shaped like a globe or has characteristics like those of a globe.
Globe valves are generally suitable for throttling applications, as the valve design determines how closely the flow can be regulated.
Plug Valve. This valve controls the flow of fluid through a conical or cylindrical plug which has a hole through it, and permits the fluid passage when this hole is aligned with the pipe axis.
Diaphragm valves include a valve body with two or more ports, a diaphragm, and a weir or seat against which the diaphragm closes the valve.
Types of Butterfly Valves. A butterfly valve has a circular disk approximately the size of the orifice of the pipe diameter.
The check valves permit flow only in one direction. These valves close when the flow rate is inverted. Also known as non return valve (NRV)
A ball valve is a quarter-turn shut-off mechanism that controls the flow of fluids through a rotating ball that has a bore through it.
Gate Valve Types. The Gate valves have three main components: the valve body, bonnet and TRIM.
This publication begins by providing a description of the types of conventional valves used in piping systems.
Pressure-relief devices are used to remove overpressure, which could result in the failure of a boiler, pressure vessel or other equipments. A pressure relief device is the last line of defense for safety.
