Valve with interchangeable outlet connections for high purity gases

A valve assembly comprising:

• a valve body;
• a first outlet bore disposed in the valve body;
• a first sealing feature disposed on the valve body about the first outlet bore;
• a first anti-rotation feature disposed on the valve body;
• and
• a clamp mechanism;
• and
• an outlet connection from a plurality of outlet connections, each outlet connection of the plurality including:
• a second outlet bore through the outlet connection, and
• a second sealing feature about the second outlet bore
• a sealing geometry,
• wherein:
• the dimensions of the second sealing feature are the same for each outlet connection of the plurality,
• each outlet connection from the plurality of outlet connections includes a sealing geometry that is different from the sealing geometries of the other outlet connections of the plurality,
• the clamp mechanism is dimensioned and configured such that:
• each outlet connection from the plurality of outlet connections may be releasably positioned against the valve body such that a flow may pass between the first outlet bore and the second outlet bore through the outlet connection, and
• the second sealing feature of the outlet connection may be urged by activation of the clamp mechanism toward the first sealing feature of the valve body to create a seal between the first sealing feature and the second sealing feature;
• and
• the first anti-rotation feature disposed on the valve body is configured and positioned such that a second anti-rotation feature of the outlet connection may be engaged, the engaging operating to limit rotation of the outlet connection with respect to the first outlet bore.
