Seals for butterfly 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 Freudenberg Sealing Technologies 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.
These Butterfly Valve seals areavailable in SILICONE RUBBER, NITRILE RUBBER, EPDM RUBBER & PTFE (TEFLON) at market leading prices.

What materials are available for butterfly valve seals, and how do they affect performance?
Butterfly valve seals are available in various materials, including SILICONE RUBBER, NITRILE RUBBER (NBR), EPDM RUBBER, and FKM. Each material offers distinct advantages depending on the application. For example, NBR is suitable for applications involving oil and fuel, while EPDM is ideal for high-temperature scenarios. The choice of seal material directly impacts the seal's durability, compression set, and resistance to chemicals.
How do butterfly valve seals prevent leakage?
Butterfly valve seals are designed to block three potential leakage paths: the sealing of pipes, flanges, and operating shafts. The geometry and material properties of the seals allow for a high pressing action that ensures a tight seal during operation. For instance, our High temperature EPDM seat DN200 is engineered to maintain effective sealing even under extreme conditions, thereby preventing leakage.
What are the benefits of using specialized butterfly valve seals from Freudenberg Sealing Technologies?
Freudenberg Sealing Technologies offers specialized sealing solutions that feature precisely calibrated material quality and torque-reducing geometries. This design allows the flap to close with lower force requirements while still providing excellent sealing capability. Our FKM seat DN250 is an example of how advanced material selection can improve performance and longevity of butterfly valves.
