Rain Bird Falcon 6504 Part-Circle Stainless Steel Rotor 4 in. Riser with SAM Check Valve

With the Falcon 6504 rotor, you can have it all — uncompromising performance, superior distribution, reliability and durability. Rain Curtain™ nozzles maximize performance and coverage. A multi-function wiper seal and tapered riser keep the stem clear of debris, providing long-term protection. Plus, heavy-duty construction makes the Falcon 6504 one of the toughest rotors in the field.

Available in full- and part-circle models with optional stainless steel riser, the Falcon 6504 is ideal for large turf sites such as parks, athletic fields, cemeteries, schools and commercial sites with spacing up to 65 feet (19,8 m).


Ratcheting stem just like standard spray bodies.

Optional stainless steel riser option helps deter vandalism on public turf areas.

Five-year trade warranty..

Easy arc adjustment (part-circle model) through top of rotor from 40° to 360°. No special tools required.

Water-lubricated gear drive for reliable, durable rotation.

Heavy-duty, stainless steel retract spring ensures positive pop-down.

Standard black rubber cover or optional purple rubber cover for non-potable water.

Seal-A-Matic™ (SAM) check device prevents puddling and erosion caused by low-head drainage.

Patented Rain Curtain™ nozzles have three ports for optimal long-range, mid-range, and close-in watering, for green grass even in the heat of summer.

Nozzles are interchangeable from the front with no special tools.

Self-adjusting stator does not require replacement when changing nozzles.

Radius adjustment screw allows radius reduction up to 25% without changing nozzles.

Small 2″ (5,1 cm) exposed diameter reduces possibility of injury in play areas.
