Abstract: A valve for cryogenic fluids that divides incoming fluid into separate outlets. The valve prevents the inadvertent leakage or reverse flow of fluid through the valve using a swing-type check valve, and may also remove undesirable debris from the fluid. The valve comprises a valve housing and at least one valve actuator. The housing includes an inlet and at least one outlet, and has an inlet chamber and at least one outlet chamber that are adapted to receive fluid from the inlet and deliver the fluid to the outlet. The inlet chamber and the outlet chamber are fluidly coupled by a valve aperture that is defined by a valve seat. The valve actuator cooperates with the valve seat to seal the inlet chamber from the outlet chamber. In one embodiment, the valve includes a check valve that is pivotally mounted in the valve housing to prevent fluid flow from the valve housing through the inlet. In another embodiment, the valve includes a pair of outlets, a pair of outlet chambers and a pair of valve actuators.

Abstract: A cryogenic gate valve having a body with a full passage formed therein. A gate has opposed faces at an acute angle with a recess formed in one face of the gate. The recess receives a sealing means that is comprised of a sealing ring having a base flange and an annular flange, and a rigid securing disk having a peripheral flange. The annular flange on the sealing ring has multiple concentric sealing ribs. The interface surface between the disk and the sealing ring extends at a taper angle to the face of the gate.
