First of all lets try to get a brief of What is a Pump? Pump is a machine or mechanical equipment which is required to lift a fluid (liquid, semi-solid, gas, steam etc) from low level to high level or to flow fluid from low pressure area to high pressure...
A ball valve is a form of quarter-turn shut-off valve that controls the flow of a liquid or gas by means of a rotary ball with a hole bored through the center and sandwiched between two seats. Ball valves do not use a hand-wheel but instead use a wrench handle to control the...

The purpose of the block and bleed valve system is to isolate or block the flow of fluid in the system so the fluid from upstream...
Butterfly Valves are quarter-turn rotary valves in which a disc-shaped closure member is rotated through 90 degree or less to open or close or regulate the flow passage. Butterfly valves may be used for flow in both directions. Unlike a ball valve, the disc is always present within the flow, therefore...
Check Valves, also known as Non Return Valves (NRV) or One Way Valves, are automatic valves that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valve open with forward flow and close against reverse flow. Check valves differ considerably from other members of the valve family and...
