Climate change is already causing continued drought in Morocco. That’s why the country has allocated around 80% of its water resources to combat desertification, a major problem in a country where a significant portion of GDP comes from agriculture. The government’s ‘Green Morocco’ project is focused on undergoing irrigation modernization in large agricultural areas — mainly a transition from sprinklers to drip irrigation.

Pressure and flow value optimization are an integral part of irrigation system design. With constant and often dramatic fluctuations in demand flow and supply pressure, valves and other components need to ensure dynamic pressure and flow control across the entire system.

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.

Water hammer due to valve closing is unfortunately a common risk as valve closing dramatically reduces flow – "blocking" the water path. In this short blog, we look at the problem and recommended solutions.

Problem:

Water hammer caused by valve slamming at closing.

  • Valve: IR-2"-100 series, commanded by external pressure (no specific application is detailed)
  • Working pressure: 50 meters / 73 psi
  • Command pressure: Not specified
  • Flow: 4 l/s (14.4 m3/h) / 63.4 gpm
  • Flow velocity: 2m/s / 6.5 f/s

What are Flow Control Valves?

Flow control valves are designed to maintain a constant pre-set maximum flow regardless of fluctuating demand or varying system pressure. Flow limiting is required at the outlets from main systems to consumers like secondary systems (main line to hydrant line; hydrant line to distribution line), reservoirs, etc. in order to protect the supplying system from over consumption.

The customer, Hainan Shuangyi, required a solution for delivering water from a reservoir on the Beipan River to an orchard irrigation reservoir on the top of a nearby mountain.

As water supply systems such as this one are prone to water hammer, a solution was needed to help protect the mainline from surge damage.

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.

In component design, there is a delicate dance between versatility and specificity. Designing for a specific application helps to ensure that you get exactly what you need. However, it can be highly advantageous both in the field and throughout the distribution and merchandising process to have a component that is suited to a wide variety of applications and situations. The trick to creating such a component is to minimize or eliminate performance compromises while still providing a versatile product.
