Home Types of Butterfly Valves (API 609) A butterfly valve is used to shut off or modulate the flow of a fluid (isolation and regulation). API 609 Centric butterfly valves (soft seated) are preferred to gate and ball valves for low-pressure and non-critical applications as they are cheaper, lighter, and easier to install. Eccentric butterfly …
Home 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, …
Home Plug Valves Plug valves are quarter turn operated and can be Lubricated or Non-Lubricated. Lubricant is injected under pressure between the plug face and body seat to reduce friction, provides port sealing and allows sealant jacking action to unseat the plug-in tapered designs. The Non-lubricated type shows mechanical design characteristics capable to reduce friction …
Home 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 …
Home Types of Ball Valves (Floating, Trunnion) A ball valve features a spherical disc to open and close the flow of the fluid. They are the industry standard for pipeline shut-off applications, as their design guarantees very tight and leak-free sealing even after years of operation. The two key types of ball valves are the …
FC TYPE GATE VALVES Gate Valve ‘FC’ type is a field-proven valve which provides reliability and interchangeability, bi-directional sealing and a non-rising stem making it ideally suited for drilling Manifolds, X-mas trees and severe service, one piece gate helps to prevent line sediment from entering the body cavity. • Full bore design eliminates efficiently pressure …
