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,
• wherein:
• the clamp mechanism is dimensioned and configured such that:
• an outlet connection may be releasably positioned against the valve body such that a flow may pass between the first outlet bore and a second outlet bore through the outlet connection, and
• a second sealing feature of the outlet connection may be urged by activation of the clamp mechanism toward the first sealing feature of the outlet connection 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.

A removable outlet connection for a valve, the outlet connection comprising:

• a first outlet bore through the outlet connection;
• a first sealing feature about the first outlet bore;
• a first anti-rotation feature;
• and
• a first sealing geometry,
• wherein:
• the outlet connection is dimensioned and configured to interact with a valve body provided with a clamp mechanism, a second outlet bore, a second anti-rotation feature, and a second sealing feature such that:
• a flow may pass between the second outlet bore and the first outlet bore,
• the first sealing feature may be urged by use of the clamp mechanism toward the second sealing feature to create a seal between the first and second sealing features, and
• the first anti-rotation feature is dimensioned to engage with the second anti-rotation feature, the engaging operating to limit rotation of the outlet connection with respect to the second outlet bore.

A valve assembly comprising:

• a valve body;
• a first outlet bore disposed in the valve body;
• an outlet connection including:
• a second outlet bore through the outlet connection, and
• a first sealing geometry;
• means for creating a seal about the first outlet bore, and between the valve body and the outlet connection;
• means for limiting rotation of the outlet connection with respect to the first outlet bore;
• and
• means for clamping the outlet connection to the valve body,
• wherein:
• the means for clamping releasably position the outlet connection against the valve body and provide a force used by the means for sealing,
• the means for sealing are dimensioned to provide for a flow to pass between the first outlet bore and the second outlet bore and use the force provided by the means for clamping to prevent leaking, and
• the means for limiting rotation limit rotation of the outlet connection with respect to the first outlet bore.
