Abstract
A block valve includes a valve body having an interior chamber between an inlet port and an outlet port, with the valve body including a vent port positioned in the valve body. The block valve further includes a valve closure element located within the chamber, with the valve closure element having a fluid passage therethrough. The valve closure element is movable relative to the valve body between a first position, where the fluid passage is at least partially alignable with the inlet port and the outlet port, and a second position, where a sealing surface of the valve closure element seals the inlet port and the outlet port from the chamber. The valve closure element includes a vent channel positioned in fluid communication with the vent port and the fluid passage of the valve closure element.
