Beschrijving
Power failure venting valve SAF 16/4 o is an electromagnetically operated vacuum accessory configured as currentless open for safe system venting when power is lost. The valve is specified with a DN 16 KF connection, matching common small-flange vacuum interfaces used on laboratory pumps and process lines. In normal operation the electromagnetic actuator holds the valve as required; upon power failure it opens automatically, allowing controlled venting and helping protect connected equipment and samples from uncontrolled pressure conditions. This compact single-unit component is intended as a dedicated spare or accessory for vacuum setups that demand a defined fail-safe behaviour. Supplied as one piece from manufacturer WELCH, the SAF 16/4 o power failure venting valve supports reliable integration into laboratory vacuum systems where electromagnetic control and currentless-open safety logic are specified.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Power Failure Venting Valve SAF 16/4 o, Electromagnetically Operated, Currentles
What is this article?
Power Failure Venting Valve SAF 16/4 o, Electromagnetically Operated, Currentles is the article on this page. Luminix Health distributes WELCH for laboratory use. It sits in Kranen & ventielen, inside Slangen, leidingen & koppelingen, in Labmateriaal.
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.
