Does a larger sprinkler increase pressure to sprinkler heads?

I want to increase water pressure to my sprinkler heads without digging up existing system. My main line feed is 1", the valves and irrigation lines are 3/4". If I increase the valve size to 1" will that provide more pressure? I am aware I could add a booster pump however electrical is not readily available for that. I inherited this system when we bought the house and don't want to redo the entire system correctly at this time, just trying to increase pressure. Thanks.

Does a larger sprinkler VALVE increase pressure to sprinkler heads?

Nope, increasing the valve size wont increase the pressure. The pressure is the pressure. Even if you had 1" valves and 1" pipe to the sprinkler heads, the pressure would be the same. You might increase the flow/amount of water available to the heads.
Sometimes the demand on the available water supply is too big. By changing the nozzles to something with less demand, you can get them to spray farther.
