3-Port Diverter Valves - Restriction?

Hi all,
Installing a new pool and I was originally going to order Jandy valves for the equipment pad but between estimated shipping times and cost, I made a last minute decision and went with Pentair valves. Grabbed some 2 port and 3 port diverter valves. The 3-Port valves surprised me. After choosing 2 inch suction size plumbing it sure looks like the valve will restrict the flow to significantly less than normal 2" flow rates. The actual "venturi" inside the valve is more a narrowed vertical opening. Is this normal for a 3-port valve? Did some searching but couldn't find an answer anywhere...

Which valves did you get? 1 1/2 inside/2" slip outside or 2" inside/2 1/2" slip outside?


The diverter, part 9, opens up 270 degrees of the water flow...


Post pics of what you have for the diverter.
