The media passing through the AKO aluminium flanged Pinch Valves used within this 36m crop spraying machinery application by a local agricultural company is suspension fertiliser. The fertiliser is a temperature of between 5-20’C. The pressure of the fertiliser is travelling through the pipework and pinch valves at 0-3 BAR.
The position of the pinch valves is on top of the applicator on the agricultural machinery, which performs many cycles per day. The amount of air used to fully close the pinch valve varies, but ranges up to 6 BAR.
The valve for suspension fertiliser is placed on a return line to the tank and is operated to keep a contact application within a desired speed range.
