Dual pressure reducing stations for control and monitoring of irrigation system

The Olmos project in Peru, is a mega project diverting water from the Huancabamba river. The project was a joint venture between the Netafim drip irrigation company which designed and executed the project, Valmont Industries, which supplied the center-pivot irrigation systems, and BERMAD which designed and supplied unique automatic hydraulic

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.

Recently, one of our customers asked how is it possible for two pilots to operate on the same hydraulic control valve without interfering with each other's operation. In this short blog, we will describe how hydraulic control valves with two pilots operate.

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.
