Gate Valves Selection Guide: Types, Features, Applications
WEBGate valves are usually divided into two types: parallel and wedge-shaped. The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Shut-off is obtained by the free-floating seat or disk gate allow the upstream pressure to seal the seat and disk against any unwanted seat leakage.
Globe Valves Selection Guide: Types, Features, Applications
WEBFeatures. Globe valves are available with features for additional precision and safety. Positioners - Positioners allow operators to identify how open or closed the valve is for throttling. Limit switches - Limit switches limit how far the valve is able to open to close to protect the internal components of the valve.
Diodes Selection Guide: Types, Features, Applications - GlobalSpec
WEBSchottky diodes are also known as Schottky barrier diodes or hot-carrier diodes. They consist of a junction between a metal layer and a semiconductor element. The metal layer, a cathode, is heavily occupied with conduction-band electrons. The semiconductor element, an anode, is a lightly doped N-type semiconductor.
Heat Exchangers Selection Guide: Types, Features, Applications
WEBPlate coil or panel coil heat exchangers are a hybrid of tube heat exchangers and plate heat exchangers. They consist of coils of tube containing a heat transfer fluid connected or adjacent to a plate, panel, or wall which holds another fluid. These devices are relatively inexpensive and simple to maintain since the coils can be easily removed.
Tubing Selection Guide: Types, Features, Applications - GlobalSpec
WEBTubing or tubes are hollow cylinders used for fluid transport, structural applications, or electrical sheathing. They are usually cylindrical in shape, but may have round, rectangular, or square cross-sections. Tubing is specified in terms of outside diameter (OD) and (depending upon the material of construction) is either rigid or flexible.
Pipe Flanges Selection Guide: Types, Features, Applications
WEBPipe flanges are protruding rims, edges, ribs, or collars used to make a connection between two pipes or between a pipe and any type of fitting or equipment component. Pipe flanges are used for dismantling piping systems, temporary or mobile installations, transitions between dissimilar materials, and connections in environments not …
Pressure Transmitters Selection Guide: Types, Features
WEBPressure transmitters are capable of performing various pressure measurements and displaying amounts in different units. Absolute pressure is a pressure measurement that is relative to a perfect vacuu m. Typically, vacuum pressures are lower than the atmospheric pressure. Gage pressure, the most common type of pressure measurement, is relative ...
Condensers Selection Guide: Types, Features, Applications
WEBCondensers are devices which accept a vapor stream and convert it to a liquid using heat transfer and/or compression. A condenser may refer to a heat exchanger used specifically for cooling gases and process fluids below their boiling points. However, condensing units (such as those in air conditioners) are used in systems which cool the ...
Laboratory Tongs Selection Guide: Types, Features, Applications ...
WEBLaboratory tongs are large pincers for grasping and lifting vessels of heat-resistant material used in high temperature chemical reactions. Tongs differ in shape are designed to pick up laboratory items including, hot evaporating dishes, beakers, crucibles, and other laboratory apparatuses. The main type of laboratory tongs are Crucible tongs ...
Lithium Batteries Information - GlobalSpec
WEBLithium manganese dioxide (Li-Mn) and lithium thionyl chloride are two types of primary lithium batteries. Li-Mn batteries make up approximately 80% of the lithium battery market. These batteries are inexpensive, feature high energy densities and can operate over a high temperature range. Lithium thionyl chloride batteries have a liquid cathode.
