Description
2/2-way ball valve, manual on/off, DN 10 KF is a compact isolation valve for laboratory vacuum and process lines that use small KF flange connections. The designation indicates a two-port, two-position ball valve operated by hand for straightforward open/close control of the flow path. Nominal size DN 10 with KF (small flange) geometry suits compact vacuum manifolds, pump inlets and accessory branches where rapid manual isolation is required. Supplied as a single piece, the unit is intended as an accessory or spare part for laboratory equipment setups. The clear 2/2-way layout keeps the flow path simple, while the manual actuator allows operators to switch between open and closed states without external power or pneumatics. This configuration from manufacturer WELCH supports routine vacuum work, system segmentation and maintenance isolation on KF DN 10 lines. The valve integrates into existing KF flange assemblies used across analytical, research and general laboratory vacuum installations, providing a dedicated manual on/off element matched to the DN 10 KF interface.

Questions about 2/2-Way Ball Valve, Manual On/Off, DN 10 KF
What is this article?
2/2-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.
