Gate Valves Selection Guide: Types, Features, Applications
Types of gate valves. Image Credit: thepipefittings.com . Wedge-shaped gate valves use two inclined seats and a slightly mismatched inclined gate, allowing for tight shut-off.. Disk flexibility is inherent to the split wedge design.This flexibility allows the split wedge to seal more easily and it reduces stickiness between the sealing surfaces in cases where the valve seats are angularly ...

Linear Actuators Selection Guide: Types, Features, Applications ...
Linear actuators are mechanical devices used to move items through a system. The device uses energy to develop force and motion in a linear manner, as opposed to a rotational motion in an electric motor.
Electrical Connectors Information - GlobalSpec
Card edge connectors (also called edge card connectors) are embedded devices that mate with the edges of single-sided or double-sided printed circuit boards (PCBs) in order to provide an external electrical connection.
Motor Circuit Breaker Sizing Calculator | GlobalSpec
Electric motors are essential devices that convert electrical energy into mechanical energy (in the form of rotational torque of a shaft). The electrical energy could be grid-supplied single-phase or poly-phase alternating current or direct current from an alternative source.
Centrifugal Pumps Information - GlobalSpec
Power Source . Pumps can be driven by a number of different power sources. The most common are electric motors, but many other types exist. AC powered pumps operate on a form of alternating current (AC) voltage, typically from an AC motor.; DC powered pumps operate on a form of direct current (DC) voltage, typically from a DC motor or battery.; Air (pneumatic) …
The Task Group responsible for alternative treatments has presented a code update for the 2023 edition of ASME Section III Divisions 1 and 5. This update includes alternative material procurement requirements that expand the existing small
Impellers Selection Guide: Types, Features, Applications - GlobalSpec
Impellers (also spelled impellors or impellars) are rotating devices designed to alter the flow and/or pressure of liquids, gases, and vapors.Impellers consist of various vanes — often blade-shaped — arranged around a short central shaft. When the shaft and vanes rotate, they suck in fluids or gases and impel them out the other side.
Network Equipment Selection Guide: Types, Features, Applications ...
Network equipment is used to combine, split, switch, boost, or direct packets of information along a computer or telecommunications network. This product area includes hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls.
