PELCO®ball valves offer an elegant, easy and quick way to close/open vacuum lines. They have a relatively high conductance with NW16 having a 13mm ID and NW25 having a 20mm ID. The 3-way change-over ball valves enable the connection of two systems to one pump. They can be used up to a vacuum level of 1 x 10-6mbar. Primarily used in backing lines on rotary or scroll pumps. Working temperature range -20 to 80°C (-4 to 176°F).
