Válvula de ángulo recto UHV completamente metálica
Our UHV all metal angle valves are the reliable solution for all applications in ultra-high vacuum. The innovative design and rotatable CF flanges allow a convenient handling and an easy installation.
The reliability of the valve is achieved by the use of optimal sealing materials. The silver-coated sealing with its very long service life is maintenance-free at more than 1000 cycles. A mechanical stop prevents the valve from too much torque that might cause damages to the sealing. Also the mechanical stop indicates when the valve is fully closed. For operating the valve a plastic hand wheel and a metal T-handle are available. The advantage of the T-handle is that it suited for heating processes and does not need to be removed.
