Flow Patterns: Hayward Manual Three-Way Ball Valves come standard with a two port "TW" ball allowing for three flow configurations within 180 degrees of rotation. With the bottom port as the inlet, the flow can be directed out the left port, out the right port or shut off. Hayward Actuated Three-Way Ball Valves come standard with a three port "NT" ball allowing for two flow configurations within 90 degrees of rotation. With the bottom port as the inlet, the flow can be directed out the left port or out the right port, there is no shut off position. A "TW" ball, used with with the proper electric actuator, adds what is typically called a "center off position" to the "NT" flow pattern of actuated valves. An optional "TP" ball, used with either manual or actuated valves, allows flow through all ports at the same time or flow shutoff.
True Union Design: This makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking down the piping connections. Just unscrew the three assembly nuts and lift the valve body out of the line.
