Description
Right-angle valve VA 40 HSE is a manually operated stainless-steel valve configured for DN 40 KF vacuum connections in laboratory and technical vacuum systems. The right-angle geometry supports compact installation where space is limited and pipe runs must change direction without additional fittings. Manual actuation gives direct operator control for isolation, venting or process switching during pump-down, system maintenance and experimental setups. Stainless-steel construction provides robust mechanical strength and chemical resistance suited to demanding laboratory environments. The DN 40 KF interface aligns with standard small-flange vacuum hardware, simplifying integration into existing manifolds, chambers and pump lines. Offered as a single-piece unit from manufacturer WELCH, the VA 40 HSE right-angle valve is intended as a durable accessory or spare part for vacuum apparatus where reliable manual shut-off and KF compatibility are required. Use it wherever a compact stainless-steel right-angle valve with DN 40 KF flanges supports safe, controlled vacuum handling.

Questions about Right-Angle Valve VA 40 HSE, Manually Operated, Stainless Steel, DN 40 KF
What is this article?
Right-Angle Valve VA 40 HSE, Manually Operated, Stainless Steel, DN 40 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.
