Übersicht The orifice sizes (1"-3 1/2") of Marley NS nozzles are large enough that many competitive nozzles will actually fit inside a Marley nozzle.


NS5 counterflow nozzles have no internal parts or narrow passageways. The attached diffusion ring will not retain even fibrous debris.

“Full cone” distribution pattern assures uniform water distribution for all film fills. Minimal spray overlap is required, providing uniform water distribution even near spray boundaries. Marley NS counterflow nozzles develop uniform water distribution over a wide range of operating water pressures.
