Abstract
A drain valve for controlling the flow of water from a source of standing water to a drain, the drain valve comprising: a valve body, an inlet in said valve body connectable to said source, an outlet in said valve body connectable to a drain, a fluid passageway through said valve body running from said inlet to said outlet, a cavity in said valve body intersecting said passageway, a gate disposed in said cavity, said gate being movable between an open position wherein water can flow through said passageway to a closed position wherein the flow of water through said passageway is blocked, a water supply line for supplying water under pressure to said cavity on one side of said gate, and a water supply valve for controlling the flow of water from said supply line to said cavity, whereby when said water supply valve is open, water flows into said cavity and moves said gate from said open position to said closed position and when said water supply valve is closed, said gate returns to said open position.
