The SM series Nickel Plated Brass and Lead Free Brass motorized 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.
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.
Features & Benefits
- Simple, 1 clip-pin actuator mounting and removal system eliminates the cost, weight, and installation time required by other valve/actuator mounting systems that require brackets and multiple fasteners
- Pre-wired with a cable lead eliminates the need for opening the actuator and wiring in the field
- Manual override for emergency operation of the valve requires no special tools, just a standard screwdriver to switch to manual operation and wrench to rotate the valve (on/off actuators only.)
- Two internal limit switches (0° and 90°) to indicate fully open and fully closed position on non modulating actuators
- 100% testing to ensure quality of all valve assemblies
- Visual position indicator
- One size actuator fits all valve sizes which simplifies and reduces inventory
- Rugged gearbox construction for extended service life
All valves can be manually operated with a large screwdriver if the actuator is removed.
