The SM series motorized brass ball valves are ideal for HVAC and industrial on/off and modulating applications. The quarter turn ball valve features a unique direct mount system that allows for extremely quick and easy actuator mounting, allowing for easy removal or replacement of the on/off or modulating compact electric actuator. Lead free brass valves are only available with on/off actuators.
Modulating Ball Valves (Control Ball Valves)
When used with a modulating actuator, there are various flow optimizers (ball port inserts) that can be selected to achieve a precise flow control range.
The addition of a parabolic disc to the full port ball valve converts the valve from a standard on/off ball valve to a more precise flow control valve. The disc, or “flow optimizing trim” makes the percentage of maximum flow increase evenly with direct relation to the percentage of the 90° rotation.
