Abstract
A water control device includes a valve pipe section with an inlet, an outlet and a lower diaphragm valve housing with an internally disposed fluid aperture. An upper diaphragm valve housing includes an extension with an adjustment screw opening for a flow adjustment screw. A diaphragm valve assembly seals and unseals to the fluid aperture by an electric motor driven mechanical actuation fluid pressure diverter assembly. The flow adjustment screw includes a tamper proof surface that can be engaged by a flow adjustment tool. A base structure and cover protect sensitive components and are removable via a cover nut that also has a tamper proof surface. A flow turbine assembly is also removably disposed within the valve pipe section. The entire water control device can be removed and replaced through the use of pipe stub fittings using connecting nuts to engage the inlet and outlet of the valve pipe section.
