Abstract
A pressure valve is configured to be selectively coupled to a vessel and includes a housing including a vent aperture configured to provide fluid communication between an internal cavity of the housing and ambient air surrounding the pressure valve, an accessory aperture configured to couple an accessory to the housing, and a seal seat positioned within the internal cavity fluidly between the vent aperture and the accessory aperture. The pressure valve includes a pressure control assembly including a seal configured to break a sealing engagement with the seal seat to provide fluid communication between the vessel and the vent aperture in response to a desired positive pressure being reached within the vessel. The seal is configured to break the sealing engagement with the seal seat to provide fluid communication between the vessel and the vent aperture in response to an operator moving an actuator of the pressure control assembly.
