Big pump trying to run small GPM.
Creating back pressure will help with that valve. Makes it SHOVE it out. Pump has to shove it.
Easier fix is open agitation up so pump is supplying boom AND dumping some back in the tank. When it speeds up, some goes to boom, some goes to tank. Mainly it lets the pump run at a normal speed, not a really slow speed like you are asking it to.
