Valves for controlling fluid passage

A valve assembly for controlling the passage of fluid between a fluid source and an output, the valve assembly comprising:

• a housing defining a channel and an aperture, the housing including an inlet configured to receive fluid from a fluid source via the aperture and an inner surface defining at least two slots;
• a pipe insertable in the housing, the pipe defining a channel and an aperture in fluid communication with the channel of the pipe, the pipe including an outer surface, at least two protuberances extending from the outer surface, and an outlet separated from and in fluid communication with the pipe's aperture via the pipe's channel, the outlet configured to couple to an output for receiving fluid from the fluid source via the pipe's channel, the pipe rotatable within the housing between a first position in which the housing's aperture is blocked by the pipe to restrict fluid from entering the pipe's channel from the fluid source through the housing's aperture, and a second position in which the pipe's aperture is substantially aligned with the housing's aperture to create a fluid path between the fluid source and the output via the pipe's channel, the inner surface of the housing adjacent the outer surface of the pipe when the pipe is inserted in the housing, and the at least two slots configured to receive the at least two protuberances to retain the pipe in one of the first position and the second position;
• and
• a fastener configured to couple to the housing and the pipe and allow rotation of the pipe between the first position and the second position, the fastener including a spring configured to bias the pipe in a longitudinal direction inside the housing in one of the first position and the second position.
