Description
BOLA GL control valve GL 18 with Ø 6 mm through bore is a two-way stopcock made entirely of polytetrafluoroethylene (PTFE), featuring a straight bore and two GL-thread connections. An integrated bellows provides motion-free sealing without wear parts; the sealing cone on the bellows is spring-preloaded to maintain reliable tightness under pronounced temperature fluctuations. Turning the adjusting nut opens or closes the valve, while the protruding indicator pin shows the degree of opening at a glance. Rated for operating pressures up to a maximum of 6 bar, the design ensures that the flow medium contacts only PTFE, giving broad chemical resistance in laboratory fluid handling. External dimensions are 80 × 44 × 83 mm (L × D × H). Supplied as a single unit with a net weight of 0,254 kg, this compact PTFE valve from manufacturer Bohlender suits demanding chemical and process applications where inert wetted surfaces and stable sealing are essential.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about BOLA GL Control Valves, GL 18, Ø 6 mm Made of PTFE, passage dia. 6 mm, adjusting
What is this article?
BOLA GL Control Valves, GL 18, Ø 6 mm Made of PTFE, passage dia. 6 mm, adjusting is the article on this page. Luminix Health distributes Bohlender 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.
