Double Seat 3 Way Pneumatic Change Over Valve for Food

The sanitary reversing valve is operated by compressed air or manual handle. By controlling the relative position of the valve stem, the valve is opened or closed, or the flow direction is changed. When the sealing seat is pushed to the upper valve body, the valve is closed. When the piston is under the action of the spring, the piston pushes the sealing seat down and drives the valve stem to close the lower valve port.

For example, when processing the milk, the product medium with other media must be excluded. Double-acting valves can ensure this application, thus being able to install switchable flow paths for two incompatible media without risk of contamination even in the event of a leak. The seat also keeps the media separated from each other. So the flow diversion valve can be used for the fluid switching in the pipeline system without pollution or mixing.
