Modular valve assemblies with optional swing out

A modular valve assembly, comprising:

• a first frame comprising a fluid inlet and a first mount and a second frame comprising a fluid outlet and a second mount, the first and the second frame each including a first mounting channel, a second mounting channel, a first receptacle, and a second receptacle;
• wherein the first mounting channel, the second mounting channel, the first receptacle, and the second receptacle of the first frame extend through the first mount;
• and
• wherein the first mounting channel, the second mounting channel, the first receptacle, and the second receptacle of the second frame extend at least partially through the second mount;
• a connection element;
• a retention element;
• a first abutment member;
• a second abutment member;
• and
• at least a first modular block and a second modular block configured to be positioned between the first frame and the second frame, the first modular block and the second modular block both including:
• a first mounting channel and a second mounting channel extending therethrough;
• and
• a first shoulder and a second shoulder;
• wherein:
• the first modular block and the second modular block are each configured to be independently rotatable about the connection element relative to each other to transition between a use position and a maintenance position;
• when the first modular block and the second modular block are in the use position:
• the connection element is configured to extend through the first channel of the first frame, the first channel of the first module block, and the first channel of the second module block and to extend at least partially into the first channel of the second frame;
• the retention element is configured to extend through the second channel of the first frame, the second channel of the first module block, and the second channel of the second module block and to extend at least partially into the second channel of the second frame;
• the first abutment member is configured to extend through the first receptacle of the first frame, to extend at least partially into the first receptacle of the second frame, and to abut the first shoulder of the first module block and the first shoulder of the second module block, wherein the first abutment member does not extend through first module block and the second modular block;
• and
• the second abutment member is configured to extend through the second receptacle of the first frame, to extend at least partially into the second receptacle of the second frame, and to abut the second shoulder of the first module block and the second shoulder of the second module block, wherein the second abutment member does not extend through first module block and the second modular block;
• such that a composite fluid flow path extends from the fluid inlet, through a first fluid flow path in the first modular block, through a second fluid flow path in the second modular block, and to the fluid outlet;
• and
• when the first modular block and the second modular block transition from the use position to the maintenance position:
• the connection element remains disposed within the first frame and the second frame;
• the retention element is removed from the second frame, the first module block, and the second modular block;
• and
• rotation of the first modular block and the second modular block about the connection element to the maintenance position:
• causes the first shoulder of the first modular block and the first shoulder of the second modular block to not abut the first abutment member;
• causes the second shoulder of the first modular block and the second shoulder of the second modular block to not abut the second abutment member;
• and
• moves the first fluid flow path and the second fluid flow path out of the composite flow path;
• and
• the first modular block comprises a first fixture for controlling or otherwise impacting fluid flow through one or more parts of the modular valve assembly.
