FUNCTION DESCRIPTION |
|
| VIP valves have the actuator built into the valve body. The moving piston is driven by air. The piston will seat if it moves in the direction of the media flow. This stops the media flow. The seat is perfectly tight. The pressure required to move the piston is independent of the media pressure. The resulting VIP valve therefore saves space and the full flow ensures minimal pressure loss. | |
Closed valve |
|
| When compressed air is supplied to bore A (bore B must be relieved), the piston seats and the valve is closed. In the case of the single-acting NC design, the piston contacts the seat unless compressed air is supplied to bore B. |  |
Transition phase |
|
| During the transition phase (shown in the picture is the conversion to the open position of the double-acting design), one of the two holes is under pressure. The piston moves axially in alternating open and closed states. In the case of the single-acting NC design, the spring closes and the piston moves towards the seat (if the valve is not controlled). In the case of the single-acting NO design, the spring opens and the piston moves away from the seat (if the valve is not controlled). The valve opening and closing cycle takes less than a second. |  |
Open valve |
|
| When air pressure is applied to bore B (bore A must be relieved) the piston moves away from the seat and the valve is opened. In the case of the single-acting NO design, the piston is furthest from the seat unless the control air pressure is supplied to bore A. |  |
