Toro 640 Series Pop-up Rotor - 180° #40 Check-O-Matic

The Toro 640 Series pop-up rotor (SKU 642-02-40) is a heavy-duty commercial sprinkler engineered for athletic fields, parks, campuses and large commercial sites. This model provides a fixed 180° part-circle coverage with a factory-installed #40 nozzle and an internal Check-O-Matic check valve to prevent low-head drainage.

• Durable construction: stainless steel, brass and engineered plastics with a standard rubber cover for long service life in demanding environments.
• Adjustable performance: factory #40 nozzle installed; nozzles are interchangeable across the 640 Series to change radius and flow.
• Operating range: recommended 40–90 psi (2.8–6.2 bar); maximum 100 psi. Flow and radius vary by nozzle—refer to the nozzle performance chart for exact values.
• Compact profile: pop-up-to-nozzle height 2 3/8 in; exposed diameter 1 3/4 in; 1" female inlet for standard lateral connections.
• Configurable options: available in Valve-In-Head (VIH), Check-O-Matic and recycled-body variants; multiple drive assemblies support different arcs.
• Water management: Check-O-Matic prevents low-head drainage to keep laterals charged and reduce runoff on slopes and low spots.

Includes installation and service instructions plus a nozzle performance chart to match nozzles to operating pressure and coverage. Designed for contractors and irrigation professionals who require a serviceable, reliable rotor for commercial installations.
