Diaphragm valves get their name from a flexible disc which comes into contact with a seat at the top of the valve body to form a seal. A diaphragm is a flexible, pressure responsive element that ...

Accelerometers are transducers designed to measure acceleration forces. Accelerometers measure proper — also known as g-force — acceleration, which can be simply defined as "acceleration felt as ...

Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. There are two main forms: the piston actuators and diaphragm actuators. Piston actuators are ...

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 ...

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 ...

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 ...

ISO or intermodal containers are used for the intermodal transport of freight. They are manufactured according to specifications from the International Orginization for Standardization (ISO) and are ...

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 ...

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 ...

Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. They are one of the most common ...

A bolt is a type of threaded hardware fastener that is used to position two workpieces in specific relation to each other. Bolts come in several configurations for their application and specification ...

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 ...
