Abstract: A valve includes a housing, a ball rotatably coupled to the housing, a handle coupled to the ball, a ball retainer coupled to the housing, and a radial seal. The housing includes an inlet, an outlet, a passage between the inlet and the outlet, and a lower housing bore. The ball includes a body, a lower trunnion, and an opening through the body. The handle is operable by a user to rotate the ball in the housing to align the opening with the passage of the housing to open the valve. The ball retainer retains the ball in the housing. The ball retainer includes a threaded portion and a shaft portion in the lower housing bore. The radial seal is between the shaft portion and the lower housing bore.

Abstract: A gas dispensing system includes a frame configured to house multiple rows of gas cylinders, a common gas manifold fluidically coupled to a gas outlet for dispensing of gas from the gas cylinders, a gas manifold for each row of gas cylinders configured to be fluidically coupled to each cylinder in the row by a respective dispensing valve, a vent manifold for each row of gas cylinders, in which the vent manifold for a given row of gas cylinders is configured to be fluidically coupled to each cylinder in the row via a respective vent valve, in which each vent valve is configured to open when a temperature on the vent valve exceeds a threshold temperature, and a common vent manifold, in which each vent manifold is fluidically coupled to the common vent manifold.
