* - All hydraulic connections on Toro valves are ⁄4" insert type.
- Control line pressure must be equal to or greater than mainline pressure.
- Control line pressure range is 40 to 150 psi.
* * Minimum solenoid voltage required for reliable electric VIH operation is 19.5 V AC
£ - Maximum of one (1) valve per station on pin type systems.
