Because of the wide distribution pattern from Polydeck's polyurethane spray nozzle heads, fewer spray heads are required per screen width.
A tapered flow orifice allows for aperture cleaning to flush out debris and particles when rotated 180° using the provided spray nozzle handle. It comes with a 3/4" male NPSM coupling for installation.
All components of the spray valve assembly, body, orifice core, handle and coupling are available separately if lost or damaged.
Five different center core opening sizes are available ranging from 5mm to 13mm, as well as a solid core for blocking off a location or setting your own orifice diameter. If your water volume needs change, the center core can easily be removed and replaced with another opening size. An optional handle is also available to make adjusting the water flow and direction even easier.
12” from nozzle: 24” – 44”
