AKO Pinch Valve Series VF

AKO Series VF – air-operated pinch valve with flange connection

The AKO Series VF is an air-operated pinch valve with flange connection for large nominal sizes at low weight – ideal for shut-off and dosing tasks with abrasive, fibrous or solids-laden media. It is controlled via a 3/2-way solenoid valve or pilot valve; no separate actuator is needed.

• Large nominal sizes at low weight
• Around 40 % less compressed air consumption thanks to the elliptical control chamber
• Flange in five designs, including steel/stainless steel bushing, internal thread or flange sleeve
