Valves are mechanical devices that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications.

Diaphragm pumps are positive displacement pump which move gases, liquids, or gas-liquid mixtures via a reciprocating diaphragm. They are highly reliable because they do not include internal parts that ...

Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Original ...

This large library of free industrial online webinars available from GlobalSpec's partners covers the big trends in engineering - everything from electrical engineering and power electronics to ...

Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that ...

V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer ...

Gear pumps are positive displacement rotary pumps that transport liquids using rotating gears. They function through the use of two or more internal gears that create vacuum pressure, propelling the ...

There are five common types of temperature instruments. Each has advantages and disadvantages. Thermocouples are accurate, highly-sensitive to small temperature changes, and quickly respond to changes ...

Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary applications. The principal types of roller bearings are cylindrical, spherical, and tapered. In ...
