COVER STORY

Handle the pressure

Knowing the basics of hydraulic control is a step toward efficient and successful irrigation.

Agricultural irrigation systems generally require adequate and constant pressure in order to operate efficiently while minimizing problems. In areas that have unavoidable pressure drops and spikes, the system may require certain control valves, regulators or compensators to protect and enable the system to perform as efficiently and uniformly as possible.

These controls have functions such as pressure regulation, pressure sustainment, pressure relief and pressure compensation. Knowing which function is necessary and where to use it takes knowledge and experience and can make or break a system design. At the same time, these products must be sized and rated for the given flow rates and pressures in order to function properly.
