The SM series actuated brass ball valves with compact electric actuators are for use in commercial heating, ventilation, and air conditioning applications. The lead-free brass automated ball valves are available in sizes from ½ to 2 inches. The devices have a one clip-pin actuator mounting system, which is stable and eliminates the cost, weight, and installation time required by valve-actuator mounting systems that require brackets and multiple fasteners.
The addition of a parabolic disc to the full port ball valve converts this valve from a standard on/off ball valve to an extremely 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. This precise flow control reduces the energy costs to maintain building temperature.
The actuators are one size, fitting all valve line sizes, which simplifies and reduces inventory levels and reduces overall project costs. The on/off actuators are available in 12 VDC, 24 VAC, or 24 VDC. The modulating units are available with 0-10 VDC or 4-20 mA control signals.
Typical applications include chilled and hot water coils for commercial applications, recycled water coils for air treatment systems, water coils for instantaneous production of hot water, static climate mixing circuits for heating systems, and convective and radiant cooling.
