The bellows-sealed right-angle valves and straight-through valves are compact, smooth operating valves suitable for high-vacuum use. Their desigh with bellows-sealed drive shaft ensures very low leak rates even during actuation of the valve. Their conductance in the medium and high-vacuum range is virtually the same as that of coresponding pipe fittings (pipe bends). The inner part with bellows can readily be changed and cleaned. The electropneumatic actuator is easily removed. The bellows-sealed valves have visual position indication. An electrical valve position indicator (Cat. No. 287 80) can also be fitted subsequently.
