Unable to hold a vacuum

I initially purchased this to use as an isolation valve in a smaller SPD setup. I connected it directly to my pump and then to my system and tried checking vacuum.I noticed right away i was unable to pull a full vacuum on the system. I broke everything down and checked all my connections. Then reconnected everything and proceeded to test my vacuum again.The second test resulted in almost the same result. I was able to vacuum down to about 1500 microns before it stalled and couldn't evacuate it…

Pros
  • The ISO-KF NW25 KF25 Flange Ball Valve is a highly efficient and reliable shut off valve that is designed to withstand the demands of a vacuum foreline setup. Its durable construction ensures that it can hold up against even the most challenging conditions, making it an excellent option for any industrial or scientific application
Cons
  • The Shut Off Valve may require some mechanical skill to install properly, making it difficult for those without experience to use effectively
