How To Install an Air Release Valve in an Irrigation Pipeline
In an industry where flow is an all-important factor, air release valves play a vital role in maximising irrigation pipeline performance.Read more
The function of a flow control valve is to regulate flow at a constant rate – regardless of inlet water pressure. This can be especially challenging to accomplish at very low operating pressures within a network.
This article explores how despite these difficult conditions, the Bermad Model 718 Control Valve is ideal for these types of applications.
The Bermad 718 Flow Control Valve is an electrically operated control valve manufactured to the highest of Australian standards. Its design features solenoids that control water flow to and from the control chamber – making the valve modulate to a consistent flow rate.
Typically, a small PLC reads a flow meter and the controller pulses the solenoids until the valve reaches the predetermined set point.
One of the key reasons this valve is so successful in lower pressures, is the double chambered design of the valve’s main body. The double chamber has no internal spring – with two distinct control chambers remote from the water source.
This unique design is engineered for the following performance:
To better understand the valve’s double chambered design, watch the animations below:
The following video shows the Bermad double chambered design operating with pressures as low as 4m, both opening and closing with real positivity.
