SF Series electronic zone valve actuator, 24 Vac, normally closed, 2-position, with spring return. Works with Siemens 599 Series zone valves with 1/10-inch (2.5 mm) stroke. UL listed for plenum installations, manual override.Description
The 599 Series Zone Valves work with any SFA/P Series or SSA/P Series electric actuator, or with the STA/P73U Series thermic actuator (See Table 5). The actuators accept one of either 24 Vac or 120 Vac power supplies signal to provide two-position, three-position or 0 to 10 Vdc control. Typical applications include hot or chilled water for zones with radiators; floor heating via manifolds; fan coil units; cooling ceilings (Zone Valves); wall-mounted boilers (zone valves); and VAV applications.
Features
Zone valves have a direct-coupled universal bonnet. SF and SSA/P actuators are UL listed. Actuators have a directcoupled installation; are hand-tightened without tools, provide manual override and visual position indication.
