Chevron seals
Chevron seals show a relatively high level of thermal expansion and do not have the elasticity of elastomers. The chevron sealing set should therefore be kept permanently tensioned using a spring element. This prevents the occurrence of deformation due to thermal influences. The spring force depends on the type and dimensions of the chevron seal profile. Chevron seals generally require separate guides for rods, spindles, etc.
By adjusting the material, profile and number of parts, the chevron sealing set can be perfectly matched to your application. Because of the excellent chemical resistance of these materials, the sealing sets are mainly applied in the chemical industry and the equipment industry

Valve seats
The valve seat is a critical component, responsible for providing a secure and reliable sealing surface for the valve. The function of this component is to ensure a perfect closure.
Vanéflon can produce different kind of valve seats in all fluoroplastics and also PEEK.
