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 ...

A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction. The diode is built by joining together two ...

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 ...

Pillow block bearings, sometimes referred to as plummer block bearings, are mounted bearings that are used to provide load support for a rotating shaft. Their mounting surface is on a plane parallel ...

Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction. The purpose of a check valve is to prevent process flow from reversing in the system which ...

Spring washers, sometimes called disc springs, are a subtype of washers. They lend their mechanical capabilities to the unique profile of the material: when subject to a load, the irregularities of ...

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 ...

Venturi vacuum generators create vacuums using a venturi chamber designed to move gases or fluids out of a region of space. Venturi or fluid jet vacuum generators rely on the flow of compressed air, ...

Butterfly valves are quarter-turn rotary motion valves used as throttling valves to control flow through a system. They can be used with many different media. Butterfly valves offer several advantages ...

Axial flow pumps, also called propeller pumps, are centrifugal pumps which move fluid axially through an impeller. They provide high flow rate and low head, but some models can be adjusted to run ...
