Description
3/2-way ball valve, manual on/off, DN 10 KF is a compact laboratory vacuum accessory for directional flow control in systems fitted with small KF flange connections. The valve combines a three-port layout with manual on/off actuation, enabling operators to switch or isolate gas and vapour paths by hand during everyday laboratory work. Supplied as one piece, it supports installation or replacement in apparatus that uses DN 10 KF interfaces. Ball-valve construction and manual operation make the unit suitable for bench-top vacuum lines, pump connections and compact manifolds where space is limited and direct tactile control is preferred. This accessory from manufacturer WELCH forms part of the accessories and spare parts range for laboratory equipment and is intended for integration with matching KF hardware and vacuum components. The DN 10 KF size corresponds to small-bore vacuum plumbing frequently used in analytical and research setups. The 3/2-way configuration allows flexible routing between ports while retaining simple manual shut-off capability. Laboratories can employ the valve wherever a compact manual multi-port ball valve with KF geometry is specified.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about 3/2-Way Ball Valve, Manual On/Off, DN 10 KF
What is this article?
3/2-Way Ball Valve, Manual On/Off, DN 10 KF is the article on this page. Luminix Health distributes WELCH 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.
