Yes. The valve with no influence is closed. The electric valve just relives the water from the upper chamber allowing the valve to open. Using the PEB makes it electrically actuated. You have a constant flow (trickle) of water from the upper chamber when the valve is open, so the water is sent into the flower bed. One thing about this particular valve is, when it starts to fail it will bypass water out of a port in the body. This helps you locate the valve since there are no wires to trace. On this job I had two leaks, one at the curb (lowest head) and one where the valve was.
