Hygienic and functionally secure
The pipe seal, the flange seal and the operating shaft seal
Hygienic and functionally secure even after countless switching operations
- butterfly valve seals from Freudenberg Sealing Technologies guarantee a reliable and long-lasting sealing function in butterfly or disk valves.
The butterfly valve seal is an essential component for blocking all three potential leakage paths: the sealing of pipes, flanges and operating shafts, in shut-off valves, flap valves and disk valves. In their materials and design, they must be configured optimally for the respective application.
Sealing solutions from our factory offer a precisely calibrated material quality and torque-reducing geometries. On one hand, they allow the flap to close with a low expenditure of force. On the other hand, they nonetheless feature a high pressing action for excellent sealing.
Free of both dead space and the penetration of contamination, the designs make possible hygienic applications for the food and beverage industry.
We can offer the FDA foodgrade rubber for your application.
