Leybold valves deliver exceptional reliability and performance, meeting the demanding requirements of vacuum technology with optimized designs for flow conductance, leak-tightness, and compatibility across all flange systems.Our UHV all-metal angle valves are reliable solutions for ultra-high vacuum applications, featuring innovative design and rotatable CF flanges for easy installation and handling. The silver-coated sealing offers maintenance-free operation for over 1000 cycles, with a mechanical stop to prevent over torque and indicate full closure. Operation options include a plastic hand wheel and a metal T-handle suitable for bake-out processes.
