Description
Ball valve VKE 25 is a stainless steel ball valve designed for KF DN 25 connections in laboratory vacuum systems. This compact shut-off component enables reliable isolation of vacuum lines where small flange interfaces are required. Constructed entirely from stainless steel, the valve withstands typical laboratory conditions and integrates directly into KF DN 25 piping. The VKE 25 model is offered as a single piece with a net weight of 1,200 kg and a gross weight of 1,400 kg, making it straightforward to handle during installation. Supplied by manufacturer VACUUBRAND, the valve supports controlled gas-flow management in research, analytical and process-vacuum setups. Its KF DN 25 geometry ensures compatibility with standard laboratory vacuum hardware, allowing quick assembly without additional adapters. Laboratory technicians employ this ball valve for sectioning vacuum manifolds, protecting sensitive equipment and maintaining system integrity during pump-down or venting cycles. The robust stainless-steel body provides long-term mechanical stability under repeated actuation. Packaged as 1 pc, the unit arrives ready for immediate incorporation into existing KF-based vacuum apparatus used throughout chemical, physical and life-science laboratories.

Questions about Ball valve VKE 25, KF25, stainless
What is this article?
Ball valve VKE 25, KF25, 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.
