Series 350 Backflush Valve Operation
A hydraulic command from the solenoid , which pressurizes the Lower Control Chamber , forces the diaphragm  actuated Plug Assembly  to move towards the Supply Port Seal , eventually sealing the valve drip tight.
This allows water flow from the filter through the Drain Port Seal .
Venting the upper control chamber causes the line pressure, together with the Spring  force, to move the valve back to filtration mode.
