AUTOMATIC DRAIN VALVE
A drain valve assembly comprising: a valve housing having an upper section (420) and a lower section (410), the lower section (410) comprising an inlet port (500) and an outlet port (600) and a water collection chamber between the inlet port (500) and the outlet port (600), the upper section (420) including a pressure diaphragm (160) across the upper section (600), the drain valve assembly further including a poppet valve (800) positioned in the housing and extending between the lower section (410) and the upper section (420), the poppet valve (800) arranged to fluidly seal the lower section from the upper section (410), the poppet valve in the water collection chamber being arranged to be normally sealingly positioned across the outlet port (600) to prevent water exiting the water collection chamber to the outlet port (600), the poppet valve (800) attached to the pressure diaphragm (160) in the upper section (420), the drain valve assembly further comprising a pressure line for providing a pressure signal to the upper section (420) such that when the pressure from the pressure line in the upper section (420) exceeds a predetermined opening pressure it causes the pressure diaphragm (160) to lift and to thus lift the poppet out of sealing engagement across the outlet port (600) such that water can drain to the outlet port from the water collection chamber; wherein the poppet valve (800) has a hollow body defining a channel (850) from a first end of the poppet valve (800), adjacent the outlet (600), and a second end of the poppet valve (800) adjacent the pressure diaphragm (160), and wherein the housing defines a vacuum cavity (810) across the second end of the channel, such that a negative pressure acting on one end of the poppet valve is balanced by a negative pressure acting in the opposite direction at the other end.
