Description
Ball valve VKE 40 is a stainless steel ball valve engineered for KF DN 40 connections in laboratory and process vacuum installations. This larger-format shut-off device provides dependable isolation of vacuum sections where DN 40 small-flange interfaces are specified. Fabricated from stainless steel, the valve delivers mechanical robustness suitable for everyday laboratory service. The VKE 40 model is supplied as one piece, with a net weight of 2,400 kg and a gross weight of 2,600 kg, reflecting its solid construction. Available from manufacturer VACUUBRAND, the component fits directly into KF DN 40 vacuum lines without intermediate fittings. It enables precise control of gas flow, sectioning of manifolds and protection of downstream instruments during pump-down or venting operations. Research and analytical laboratories rely on such valves to maintain system integrity across chemical, physical and materials-science applications. The stainless-steel body ensures long-term dimensional stability under repeated actuation cycles. Packaged as 1 pc, the ball valve is ready for immediate installation into existing KF-based vacuum apparatus, supporting efficient workflow organisation in modern laboratory environments that utilise standardised flange technology.

Questions about Ball valve VKE 40, KF40, stainless
What is this article?
Ball valve VKE 40, KF40, stainless is the article on this page. Luminix Health distributes Vacuubrand for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
