Bolts Selection Guide: Types, Features, Applications - GlobalSpec
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 variances. Since the terms "bolt" and "screw" were in use before the advent of easily-produced helix fasteners, they are often synonymous.
Screws Selection Guide: Types, Features, Applications - GlobalSpec
A cone point is very sharp and will provide an accurate pilot for threading. Type-A points are best utilized as replacement screws or with predrilled holes in thin metals. Type-B points are similar to Type A, but are meant for thick metals. Type-AB combines the precision point of Type A with the ruggedness of Type B.
Electrical Connectors Information - GlobalSpec
Electrical connectors are devices that join electrical circuits together. Most connectors are removable or temporary, but some can be permanent. Connectors make electronic products easier to assemble and manufacture. They also ease circuit repairs and allow flexibility in design and modification.
Gate Valves Selection Guide: Types, Features, Applications
Gate 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.
Motor Circuit Breaker Sizing Calculator | GlobalSpec
Pout=mechanical power output. PF=Power factor. V=Line voltage. E=The efficiency of the motor. Keep in mind that this circuit breaker sizing only considers motor overload, which happens when the operation of a motor (in excess of its normal, full-load rating) persists for a long enough time that it damages or overheats the motor.
Pneumatic Valve Actuators Selection Guide: Types, Features ...
Pneumatic actuator for valves and dampers. Video Credit: Industrial Controls / CC BY-SA 4.0 Actuation time is the time it takes to fully close the linear motion valve.. Acting type is an additional specification.. With single-acting devices, fluid pressure actuates the valve in one direction while a compressed spring actuates the valve in the other.. With double-acting devices, fluid pressure ...
Globe Valves Selection Guide: Types, Features, Applications
Features. 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.
Heat Exchangers Selection Guide: Types, Features, Applications
Plate 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.
Washers Selection Guide: Types, Features, Applications - GlobalSpec
There are many different types of washers for a variety of applications. Lock washers are used to secure fasteners. Spring washers are a load bearing device that provides a preload between two surfaces. Other common types include flat washers, C-washers, D-shaped washers, countersunk or finishing washers, fender washers, SAE washers, torque ...
Accelerometers Selection Guide: Types, Features, Applications
A device which measures ±2 g is suitable for measuring the movement of robots, vehicles, or aircraft. For applications involving measurements of sudden stops or violent changes in direction, a ±5 g or greater accelerometer is recommended. Accelerometers are also limited by the range of vibration frequency they can sense, and must be matched ...
