ABSTRACT:
A valve is mountable in an opening in a gated pipe to control water flow, particularly in a cablegation system. A gasket is mountable in the irrigation pipe opening and a hollow leg of a T-shaped valve housing is inserted into the mounting member. The housing has a hollow, open-ended tubular portion which receives a hollow valve member. The valve member has an enlarged cap and a side opening alignable with the housing leg, the degree of alignment controlling the amount of flow. The valve member can also include a check valve.
