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.
Bolts Selection Guide: Types, Features, Applications - GlobalSpec
WEBA 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.

Rotameters Selection Guide: Types, Features, Applications
WEBThere are several features that make variable area flow meters useful for many applications. Variable area flow meters offer mechanical flow measurement while using a single moving part. This ensures measurement reliability and easy installation. It also means that the rotameter can be used in areas with no power.
Rotary Switches Selection Guide: Types, Features, Applications
WEBThere are two basic styles: single-deck and multi-deck. Each deck is a round plate with an arrangement of contacts. Single deck rotary switches can control several circuits at a time. Multi-deck rotary switches can control several circuits simultaneously. Multi-deck (left) and Single deck (right) rotary switch.
Level Sensors Selection Guide: Types, Features, Applications
WEBA sensor is able to detect a change and communicate that change with a user. Level sensors are generally designed for a specific application, rather than general application. There are two basic level-measurement types, point level and continuous level sensors. Below is a video which explains each measurement.
