Fluid control circuit for wet abrasive blasting

A fluid control circuit for a wet abrasive blasting system, comprising

• a multiport selector valve comprising a fluid inlet (G), a first fluid outlet (H), a second fluid outlet (I) and a third fluid outlet;
• a first piping system (102) in fluid communication with the first fluid outlet (H);
• a second piping system (106) in fluid communication with the second fluid outlet (I);
• and a jumper piping system (107) between the first piping system (102) and the second piping system (106);
• a third piping system in fluid communication with the third fluid outlet, wherein the third fluid outlet (J) prevents fluid flow from the fluid inlet (G) to any of the first piping system (102), the second piping system (106) and a fourth piping system (K), and the third fluid outlet provides fluid flow to a check valve in the third piping system.
