Series Description
The Siemens 599 Series zone valves work with any SFA/P Series or SSA/P Series electric actuator. The actuators provide two-position, three-position, or 0-10 VDC control. Typical applications include hot or chilled water for zones with radiators, floor heating via manifolds, fan coil units, cooling ceilings, wall-mounted boilers, and VAV applications.
