Applications 
The divert seat valve is applied to the food-processing industry, beverage, pharmaceutical and fine chemicals industries. 
Seat valves are operated automatically by a single-acting or a double-acting pneumatic actuator. By supplying compressed air, the shaft is moved to place the valve in the "open" or "closed" position. 
This valve can bear high pressure up to 30 bar, but depend on the type of actuator 
The 180o rotation of the pneumatic cylinder to realize the interchange of normally open and normally closed.
