SS304 Stainless Steel KF25 Vacuum Angle Valve — Manual LType Valve Key benefits Reliable vacuum isolation: Designed for use in vacuum systems to provide positive, manual isolation of ports and lines using standard KF25 fittings. Durable materials: Machined from SS304 stainless steel for corrosion resistance and long service life in laboratory and industrial environments. Spacesaving rightangle layout: Ltype (angle) body lets you change flow direction and mount valves in compact or constrained spaces without added tubing bends. Simple, tool operation: Manual actuation offers direct, intuitive control for frequent operations, maintenance, or test setups. What it does and why you need it Provides a compact, stainlesssteel solution to isolate, redirect, or shut off vacuum flow on KF25 (NW25) flanges. It simplifies system layouts and reduces the need for extra tubing or adapters. Useful when you need reliable, repeatable manual control of vacuum lines—such as isolating gauges, switching between pump lines, or temporarily sealing chambers during maintenance. Key attributes Material: SS304 stainless steel body and internal components where applicable for strength and corrosion resistance. Connection standard: KF25 (also known as NW25) flange compatibility — compatible with standard KF centering rings and clamps. Valve type: Manual Ltype (angle) vacuum valve — 90degree flow path for directional control. Operation: Handactuated for open/close control; suitable for frequent manual use in bench and field environments. Sealing: Designed to work with standard KF centering rings and elastomer Orings to achieve vacuumtight seals when properly assembled. Typical uses: vacuum and roughvacuum systems that use KF25 fittings. Typical applications / use cases Laboratory vacuum lines: Isolate vacuum gauges, feedthroughs, or sample chambers quickly during experiments or routine maintenance. Vacuum system configuration and testing: Temporarily redirect flow or isolate sections when swapping pumps, installing sensors, or performing leak checks. Research and smallscale production equipment: Use in benchtop vacuum assemblies, thinfilm deposition test rigs, or vacuum ovens where compact directional control is needed. Installation and handling notes Use with matching KF25 centering rings and clamps for proper sealing; ensure Oring condition and correct placement before pumping down. Handtighten clamps and confirm valve handle position when opening or closing. Do not force the handle; excessive torque may damage the sealing ring or clamp. Inspect Orings periodically and if hardened or damaged to maintain vacuum performance. Compatible with typical laboratory vacuum oils and cleanroom practices when SS304 is suitable for the process media. Why choose this valve Straightforward, dependable performance for KF25 vacuum lines without added complexity. SS304 construction balances corrosion resistance and affordability for generalpurpose vacuum use. Angle configuration reduces tubing complexity and saves space while providing manual, direct control.
