Hydraulic Flow Control
When we need to limit the flow using hydraulic methods (as opposed to electronic methods), the flow is not continuously measured & sampled (only during setting). Therefore, pilots are designed to hydraulically sense the differential of pressure or force/velocity associated with the varying flow.
An internal control valve, also known as a tubeless valve, is commonly used as an on/off valve in residential landscaping and turfs applications.
The use of internal control valves is less common in commercial irrigation but can be found quite often in greenhouse applications as they allow operational flexibility (N.O. valve and N.C. valve). Internal control valves can be also found installed in the in-field headworks of some agricultural communities around the world.
