Suction control valves are actually installed on the discharge of the pump between check and test tee, sensing line runs to suction. TD Unless an applicable code supercedes NFPA 20 they're allowable in new installations. From NFPA 20 2016: 4.16.10.1 Suction pressure regulating valves that ar

I can't do the subject justice of explaining how they work. But I'm curious why you wouldn't use the industry standard solution to this concern, a low suction control valve? EG http://www.cla-val.com/fire-protection-pump-suction-control-valve-p-188-l-en.html 50B-5KG Fire Protection Pump Suctio
