Product Detail

FLS Valve Spring Energized Face Seal

It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.

Internal and external lip seals energized with v-springs are suitable for static and slow dynamic applications. The spring preload is from light to medium, which can maintain low friction. Since the V-spring allows the seal to handle slight misalignment, some seal deflection can be tolerated without permanent deformation.

For high pressure applications, the length of the column base of this seal can be increased, and for high pressure applications, it can also be combined with the support ring.
