ST VALVE CONFIGURATION: ST-V30K
For some, the preferred approach to designing synthetic turf irrigation systems is the "block" type configuration with remotely located valves that are off the synthetic surface. The benefit of this configuration is that it removes all high-pressure mainlines from beneath the synthetic surface. Through the use of a remotely located isolation valve, constantly pressurized supply lines to the quick couplers can be removed from beneath the synthetic surface as well.
For others, the preferred approach is to use valve-in-head (VIH) rotors. However, typical VIH rotors have an unacceptably high-pressure loss at the high flows and pressures that are inherent in all synthetic turf irrigation systems. As a result, the Hunter ST System utilizes a valve adjacent to head (VAH) configuration. This design lowers the pressure loss down to a very acceptable 0.15 bar; 15 kPa loss at 65.0 m3/hr; 1,082 l/min through the valve assembly (see slideshow at top of page). The ST-V30K includes a remotely located On-Off-Auto selector and solenoid manifold assembly. This convenient features brings valve manual control functions and solenoid splice connections closer to the surface for easy access. (not shown)
