VIP (new model) - Pneumatic Coaxial Valve - diagrams and breakaway torque -

Working principle
A VIP valve (patented by OMAL exclusively) is a proper automatic valve embodying both interception device (between pipe C-D) and control device (A-B).
It works thanks to the internal movement of a piston supplied with air. At the end of its stroke (a VIP valve is an ON/OFF valve), the piston presses on the seat seal or moves away from it letting the intercepted fluid flow or stopping it from flowing. As the seat is perfectly tight and the intercepted fluid pressures discharge on it, the pressure necessary to move the piston is completely independent of the fluid pressure. As a result OMAL has been able to design a light space saving and lasting valve. Its full bore and its improved internal dynamics allow minimum pressure losses, too.

Closed valve
Supplying the hole “A” with air (the hole “B” must be discharging) at the end of its stroke the piston presses on the seat seal: the valve is closed.
As in Spring Return N.C. executions the spring is in “A”, if there is no control, the piston will touch the seat seal: therefore, the preferable position is the closed one.

VIP (new model) - Pneumatic Coaxial Valve - specifications -

Transitionary phase
During the transitionary phase (the picture shows the opening transition in a Double Acting execution), one of the two holes is supplied. The piston moves axially changing the previous closed or open state. In Spring Return N.C. executions, the closing is caused by the spring (if there is no control). In Spring Return N.O. executions, the opening is caused by the spring (if there is no control). Both opening and closing transitionary phases last less than a second.

Opened valve
Supplying the hole “B” with air (the hole “A” must be discharging) at the end of its stroke the piston is at maximum distance from the seat seal: the valve is open.
As in Spring Return N.O. executions the spring is in “B”, if there is no control, the piston will be away from the seat seal: therefore, the preferable position is the open one.

LIMIT SWITCH

VIP can be provided with inductive limit switch (magnetic contact) and signal LED. Limit switches can be easily mounted in the integrated slots and fixed with a screw. Since the magnets are situated inside the valve, they must be mounted while assembling the VIP and not afterwards. For this reason, in case needed, magnet must be requested at VIP order phase.
The maximum fluid temperature must be lower than the maximum temperature supported by the limit switch.
