Gas control valve and related systems and assemblies

A system comprising:

• a source of liquid;
• and
• an assembly comprising:
• a reservoir fluidly coupled to the source of liquid, and a gas control valve coupled to the reservoir, wherein the gas control valve is configured to allow gas to be released from the reservoir as the reservoir is being filled with liquid from the source of liquid, and allow gas to fill the reservoir as liquid is being drained from the reservoir, wherein the gas control valve comprises:
• a valve body comprising (i) a neck portion coupling the gas control valve to the reservoir, wherein the neck portion comprises a port configured to receive fluid from and provide fluid to the reservoir, (ii) a valve chamber, (iii) a seat formed by an interior surface of the valve body, and (iv) one or more flow directing features formed about the seat,
• a float ball disposed within the valve chamber, wherein the one or more flow directing features formed about the seat are configured to allow fluid flowing from or to the port to pass through the one or more flow directing features when the float ball is seated at the seat,
• a seal disposed within the valve body, wherein when liquid enters the valve chamber and reaches a particular level within the valve chamber, the float ball is configured to float on the liquid until it reaches the seal, thereby sealing the valve chamber,
• a filter disposed within the valve body,
• a spacer interposed between the seal and the filter such that the spacer directly contacts the seal and the filter, and
• a cap coupled to the valve body such that the cap encloses the valve chamber, wherein the cap comprises an opening configured to allow gas to flow therethrough into the valve chamber from an external environment of the gas control valve or allow gas to flow out of the valve chamber to the external environment.

A method comprising:

• providing a valve body comprising:
• (i) a port configured to receive and provide fluid therethrough, (ii) a channel for communicating fluid to and from the port, (iii) a valve chamber formed within the valve body, (iv) a seat formed by an interior surface of the valve body, and (v) one or more flow directing features formed about the seat;
• placing a float ball within the valve chamber to be seated at the seat formed in the valve body, wherein the one or more flow directing features formed about the seat are configured to allow fluid flowing from or to the channel of the valve body to pass through the one or more flow directing features when the float ball is seated at the seat of the valve body, and wherein the valve body comprises a conical surface and a cylindrical surface, wherein the one or more flow directing features are formed in the conical surface, and wherein the cylindrical surface is configured as a recessed area in the interior surface of the valve body surrounding the float ball such that the valve body has an enlarged inner diameter around the float ball to increase flow area around the float ball;
• positioning a seal on a shoulder formed by an interior surface of the valve body, wherein when liquid enters the valve chamber and reaches a particular level within the valve chamber, the float ball is configured to float until it reaches the seal, thereby sealing the valve chamber;
• placing a filter within the valve body;
• and
• coupling a cap to the valve body such that the cap encloses the valve chamber and interfaces with the filter.
