The filling control valve VCLQV are to be used to signal and ensure the connection of hose in silo or deposit installations or any other tranport system due to the swiveling lever and control the transport or distribution for dusty and powdery, granulated and grainy bulk goods or viscous or liquid products due to the pneumatic valve. The models are certificated for use in potentially explosive Dust atmospheres hazardous areas.

While coupling the counter coupling or hose coupling, the lever is swivelling besides and the limit switch will be actuated. At the ending of the coupling, the lever moves back to the initial position and the switch is disengaged.

Inside the valves there is an elastic hose made of NRE that is squeezed either by compressed air or by water pressure. The existing solids are encolsed due to this compression and when there is no pressure in the valve, the hose opens and returns to the original shape allowing the flow of product.

Mount the indicator using the counterflange.

The lever must be installed over the connection, approximately at medium height and when it is mounted to inclined or horizontal tubing, the swivelling lever limit switch always must be mount on the top side. The lever must fall trough his own weight in the drafted final position.
