Product Description
Keeping elastomers out of contact with your process stream reduces contamination and swelling, and this straight valve does it by eliminating the tip O-ring. It offers the same fine, threaded control found throughout the HI-VAC line, with grease-free operation for clean vacuum work.
This listing is for Kimble catalog number 826600-0004: HI-VAC Straight Valve with PTFE Plug, without Tip O-Ring, Bore Range 0-4 mm. The body is borosilicate glass 3.3, and the primary seal is an FKM O-ring on a tapered seat. The non-rotating PTFE shaft handles 230 C continuously or 275 C intermittently. It opens as a bleed up to half a turn and fully at one and a half turns, in three bore ranges. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
