Recirculation block

A recirculation block comprising

• a top face and a bottom face that are connected by a right side face, a left side face, a front face, and a rear face;
• a first junction block entry port and a second junction block entry port, wherein the first junction block entry port and the second junction block entry port are defined by the bottom face;
• a first side block entry port and a second side block entry port, wherein the first side block entry port is defined by the right side face, and the second side block entry port is defined by the left side face;
• and
• a first exit port and a second exit port, wherein the first exit port is in fluid communication with both the first junction block entry port and the first side block entry port, and wherein the second exit port is in fluid communication with both the second junction block entry port and the second side block entry port.

A recirculation block for recirculating fluid within a spray system, the recirculation block comprising:

• a first junction block entry port;
• a first side block entry port;
• a first exit port;
• a first internal check valve;
• and
• a first series of interconnected channels comprising a first junction block entry channel in fluid communication with the first junction block entry port, a first side block entry channel in fluid communication with the first side block entry port, an internal check valve channel in fluid communication with both the first junction block entry channel and the first side block entry channel, and an exit port channel in fluid communication with both the internal check valve channel and the first exit port;
• and
• wherein the first internal check valve is positioned within the internal check valve channel to selectively allow fluid to flow from either the first junction block entry port or the first side block entry port to the first exit port.
