The Goldline/Hayward GVA-24 Valve Actuator can be mounted on top of a 3-way valve in four different positions relative to the 3 ports of the valve. If the actuator is mounted in the standard,most common, position, the actuator cams do not have to be changed. If the actuator is mounted in any of the other three positions, the cams of the actuator will have to be reset. This guide identifies the location of the cams and shows how to adjust them. It also shows you how to sync this actuator with other actuators you may be installing.
STANDARD MOUNTING A - This picture shows how a Goldline Valve Actuator would be mounted in the most common, standard position. The body of the actuator would lie over the center port and the water would flow into the center port and out the end ports. The next picture shows a drawing of all four mounting positions.
FOUR MOUNTING OPTIONS - The Goldline Valve Actuator can be mounted on top of most diverter valve products in any of the four mounting options shown here. Depending on how the water flows into and from the three ports, cams within the actuator will generally have to be changed in accordance with the Cam Setting Table shown next.
CAM SETTING TABLE - This table is used to determine the cam settings for any of the four actuator mountings. As you can see the cam settings are based on both the actuator mounting and the direction of water flow. For example, for Mounting A, if the water enters port 2 (the center port and flows out ports 2 and 3 (the end ports) both the lower cam and the upper cam will be set 12 o'clock. This is the common, standard setting used in most installations. In another example for Mounting A, if the water enters port 3 and exits ports 1 and 2, you would have to set the lower cam at 3 o'clock and the upper cam at 6 o'clock. Note: all clock settings are referenced from the small slot on the shaft. See the picture in the next step. One other note. This table shows the setting for valves used to DISCHARGE water (after the pump). For valves on the suction side of the pump (before the pump), the table is the same except the headings in columns 2 and 4 would be switched. Column 2 would read "PORT WHERE WATER EXITS", and Column 4 would read "PORT WHERE WATER ENTERS".
SETTING CAMS - The balance of this guide provides a couple of actual examples for setting the cams: two for Mounting A - including the Standard position; and two for Mounting B.
REVIEW WATER FLOW FOR OPTION A2 (STANDARD) DISCHARGE - Note the flow of the water through the valve. For this option the water must flow into the center port and out either or both of the end ports. The center port will always be open. Either of the end ports can be shut off with the valve. This is the configuration for a discharge valve after the pump. An example of this use is water flowing from the filter to the pool or the spa or both.
REVIEW WATER FLOW FOR OPTION A2 (STANDARD) SUCTION - To configure this actuator/valve for an A2 setting on the suction side of the pump, the water flow will be reversed. Water will come from either or both ends and will exit out the center port. An example of this use is water coming from the pool drain or the skimmer or both, and exiting to the pump. In either setup, discharge or suction, the cam setup will be A2. The common criteria for both setups is that the A2 the center port is always open regardless of which way the water flows in it. Only the end ports can be closed off.
REVIEW WATER FLOW FOR OPTION B2 - For a B2 setup up (discharge), the water will flow into port 2 and be discharged into port 1 or port 3 or both. You will note that the water flow is the same as for A2. The cams have to set differently because the actuator as mounted was rotated 90° from the Mount A position. The control of water flow through the valve is the same for both A2 and B2 (and C2 and D2 for that matter).
