Optional Valve Actuators
For installation, refer to the mounting instructions included with the Hayward GVA-24 actuator or
equivalent. After configuring and first operating the valve, note that the internal cams in the actuator
may have to be adjusted depending on the way the actuator is mounted on the valve and the desired
valve action.
