Single claw-clamp assemblies are used to mate a clamp-style ISO Large-Flange™to a threaded bolt-style Large-Flange™, such as on a gate valve. The vacuum seal is made by compressing the o-ring between the mating flanges. This is done by alternately wrench-tightening opposing pairs of clamps until the first metal-to-metal contact is made between the inner surfaces of the flanges and the spacing lip of the centering ring.
