Pure Gas Valve
This valve is used for high-purity gaseous media. When the valve is opened
or closed for controlling the volume of flow, contamination of the gas is
For a hand-operated unit, housing 1 of the valve may take the form of a metal
or plastic pistol housing. Bore 2 in housing 1 accommodates a hose 3, for
example, a silicone hose. Hose 3 exits from grip 4 of pistol housing 1 and is
connected to the gas pressure source.
Housing 1 has a recess 5 in which a plunger 6 is guided, compressing hose 3
by the tension of spring 7 in such a manner that the gas flow is interrupted. An
actuating level 8 is pivotally mounted on actuated in the direction of the arrow
against spring 7, the flow cross-section of hose 3 is continously increased,
permitting the gas to flow,without particles caused by abrasion impairing its
purity. In addition, the valve functions reliably regardless of any wear of the
