API valve Archives - Projectmaterials

Type of valves used in petrochemical downstream applications and pipelines (gate, globe, check, butterfly, pinch, plug, y-strainers, etc)

Gate Valve for Piping (API 600, 602, 603)

What is a gate valve? It is a shut-off device to open and close the flow of the fluid conveyed by a piping system (or a pipeline). A gate valve is a bi-directional valve, as the fluid may flow in either direction. The installation of this type of valve creates a modest pressure drop in the pipeline, lower… read more »

Globe Valve BS 1873 and API 602

What is a globe valve? When shall it be used instead of gate and ball valves? In this article, we illustrate the scope of this type of valve (which is, in a word, to regulate the flow), the differences with other types of valve, the alternative designs, and specifications (BS 1873  for the cast steel… read more »

Check Valve BS 1868, API 6D, API 602

A check valve prevents potentially damaging backflows to protect equipment like pumps and compressors. Non-return valves allow the flow of the fluid in one direction only and block reverse flows. This type of valves is available with cast and forged bodies (BS 1868, API 6D, API 602) and in several designs as swing, ball, lift, stop… read more »
