Seafood is a staple in nearly every Chilean's diet. Shellfish such as loco (abalone), erizo (sea urchin) and piure (an unusual red invertebrate) join more widely known fish, including sardines, salmon, congrio (conger eel) and atÃºn (yellowfin tuna).
To work efficiently, pipes need a way of regulating how much fluid can pass through them; they also need a way of switching the flow off completely. That's the job that valves do: valves are like mechanical switches that can turn pipes on and off or raise or lower the amount of fluid flowing through them.
A gate valve is a valve that opens by lifting a gate from the path of the fluid. A ball valve is a valve that opens by turning a handle attached to a ball inside the valve. Th â¦ e ball has a hole in the middle so that when the hole is lined up the input side and the output side of the valve, flow occurs. globe valve is a type of valve used for regulating flow in a pipe, consisting of a movable disk-type element and a stationary ring seat in a spherical body. Usually the globe is moved in and out of the flow by a handle connected to a threaded stem.
