Butterfly Valve Standards Summary
A butterfly valve is a valve that uses a rotary motion of its circular disc to control the flow rate and pressure of a substance. Butterfly valves come in several standard designs and configurations, and each has its own set of rules and guidelines as set out by ......
Six bearing standards
Introduction
Bearings are mechanical components that support a load while allowing relative motion between two components. The practical use of bearings dates back to ancient Greece, where they were used in simple machines such as pottery wheels.
Bearings are often categorized by their rolling e......
