RD1800 SAM PRS series pop-up bodies (SAM + pressure regulation)

This pop-up body includes a check valve to prevent the water escaping from the sprinkler & pipe when the system turns off. This can prevent unsightly wet areas around the sprinklers, especially if the sprinkler is in a low area.

It also includes a pressure regulating valve which makes each sprinkler in your system operate at the correct pressure for your nozzles.
