Patent abstract
A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.
