We've mounted a Goldline Hayward Pool Valve Actuator on top of a Diverter Valve to automate the rotation of the Valve Handle through a user controlled panel. This guide shows you how a Pool Valve Actuator works. For information on installing an Actuator see our guide on "How To Install a Pool Valve Actuator". For more information on typical applications of a Pool valve Actuator see our guide on "How To Use a Pool Valve Actuator".
VALVE OPEN - First a little refresher on how a Diverter Valve works. The Valve handle is connected to a paddle inside the Valve which can be positioned to shut off one of the two end ports. In the configuration shown in the picture, the handle is positioned between the two end ports leaving the valve open in all three ports. Note: a yellow “T” is superimposed over the Handle to highlight the position of the Handle and paddle. As positioned, the Valve allows water to flow in from the Pool Drain and the Skimmer ports, and to exit to the Pump through the lower center port.
INSIDE ACTUATOR – The inside of the Actuator with the cover off is shown here. Two Cams are attached to the bottom of the Shaft: The lower Cam determines the limit of the Shaft's counter-clockwise (CCW) rotation. The Shaft will rotate CCW until the point of the lower Cam comes in contact with the left (CCW) switch. The upper Cam determines the limit of the Shaft's clockwise (CW) rotation.
CAMS SET FOR ABOVE OPERATION – All settings are reference with the smallest slot in the Shaft identified as 12 o-clock. We want to set this Actuator so that it rotates clockwise to 3 o-clock to shut off the Skimmer, or rotates counter-clockwise to 9 o-clock to shut off the Main drain. For this operation, we will set both the upper and lower Cams at 12 o-clock - stacked on top of each other. For more information on appropriate Cam settings, see our guide on "How To Set and Sync the Cam on a Goldline/Hayward Pool Valve Actuator"
VARIATION – To show the flexibility of this Actuator, we've selected this variation of control that allows partial flow through the skimmer instead of shutting it off completely. With the Valve Handle stopped in a 50°+ position, the Skimmer port will only be partially closed off allowing some water to flow from the Skimmer.
CAMS SET FOR VARIATION - To set up the Actuator for partial Skimmer water flow, set the upper Cam at about 2 o-clock instead of 12 o-clock. As the Shaft rotates clockwise, the upper Cam will come in contact with the CW switch sooner causing the Handle to stop at an intermediate shutoff position..
