Abstract
A valve for controlling the flow of cryogenic fluid. The valve includes a valve body and a sealing member pivotably mounted within the valve body. The valve also includes an actuator mechanism that pivots the sealing member from a closed position to an open position to allow flow of fluid through the valve body. The sealing member provides a seal against a portion of said valve body to substantially prevent flow of fluid through the valve in the closed position. A linkage connects the sealing member and the actuator mechanism. The linkage is capable of translating the direction of a force from the actuator mechanism to a direction suitable for pivoting the sealing member toward either the open position or the closed position.
