Toro 570Z Pro Series Check Valve - 89-5896 (570CV)

Replacement one-piece check valve designed for Toro 570Z Pro Series pop-up sprinklers. The 570CV (SKU 89-5896) prevents low-head drainage and helps keep landscapes healthy on slopes, long lines, and mixed-elevation systems.

• One-piece check valve (570CV): Prevents low-head drainage and maintains a water column on elevation changes up to 10 ft (field or factory install).
• X-Flow® water shut-off: Built-in X-Flow device restricts water loss by approximately 99% if a nozzle is removed or damaged, reducing erosion and wet hardscape hazards.
• Zero-flush seal & reliable retraction: Zero-flush seal prevents discharge at pop-up and improved seal material with a robust retraction spring ensures consistent performance.
• Pressure management: 570Z risers maintain an outlet pressure near 2.1 bar (30 psi) to minimize misting; PR/PRX models are suited for high or varying pressures.
• Compatibility & specs: Works with Toro 570Z Pro Series risers and standard ½" female NPT inlet; available riser heights and flow ranges accommodate small to medium landscape designs.

Designed for professional irrigation and contractor use, the 570CV installs easily in new or existing 570Z heads and allows dry nozzle and filter replacement while the system is running. See included documents and Toro product literature for model-specific install steps, riser height options, and flow tables.
