Abstract
A technique facilitates valve operations in many applications including well related applications. A valve utilizes a piston which moves along an arc. The valve has an outer housing and an inner housing spaced to create an arcuate pressure chamber which extends along the arc. A piston is mounted in the arcuate pressure chamber for movement along the arc. A hydraulic force or other force may be selectively applied directly against an end of the arcuate piston to shift the arcuate piston along the arc. In some applications, the piston comprises a cutting edge oriented to enable performance of a cutting operation.
