Extended-Life (XL) Design Response
When leading OEM’s came to ANCORP looking for a more durable valve for today’s harsh coating processes, ANCORP engineers went to work testing new stem designs – the XL design was born. This patented design extends the stem seal life by 10X and features a fully stabilized stem along with all the other features of ANCORP ball valves. In short, the XL ball valve reduces the need for valve maintenance, decreases tool downtime, and increases throughput. It’s the reason ANCORP remains the leading innovator in vacuum ball valves.
The corrosive-resistant design of ANCORP vacuum ball valves makes them ideal for isolating reactors, traps, and scrubbers on vacuum coating tools used for MOCVD, PVD, CVD, and other thin-film coating processes.
Ball valves offer a straight-through, unimpeded flow (or a diverting flow in 3-way ball valves) with a minimal valve body footprint. Due to their unique design, ball valves are less sensitive than other vacuum valves to particulate contamination; therefore, they are especially useful in vacuum applications with high amounts of particulate effluent. For example, ball valves are almost always used to isolate scrubbers and traps downstream of the rough pumping system.
XL Benefits |
- Stabilized stem seal to eliminate atmospheric intrusion into the process line
- Sealing capabilities maintain vacuum under high temperature/harsh process conditions
- Stem seal assembly accommodates all perfluoroelastomers (FKM or FFKM) (i.e. varying TCE’s)
- Increased the MTBFF of the valve 10X
- Improved stem seal assembly life 100X
- Reduced end-user maintenance complications
