Description
Two- and Three-Way Zone Valves have a 1/10-inch (2.5 mm) stroke.
The Zone Valves work with any SFA/SFP Series, SSA/SSP Series
electric actuator, or with the STA/STP Series Thermic actuator.
The actuators accept one of either 24 Vac or 120 Vac power supply
signal to provide on/off, oating or 0 to10 Vdc control.
Features
• All metal plug and seat for superior control
• Direct-coupled universal bonnet — install actuators
without tools
• Sweat or NPT end connections
• Standard 2.5 mm stroke
• Change from Normally Open to Normally Closed by simply
changing out the actuator
• Visual position indication
• SFA/P and SSA/P actuators are UL listed for plenum installations
• Order separately or with any SFA/SFP Series or SSA/SSP Series
electronic actuator, or with ST Series Thermic actuator as a
complete assembly
Applications
Typical applications for Two- and Three-Way Zone Valves are hot or
chilled water for zones with radiators; oor heating via manifolds;
fan coil units; cooling ceilings; wall-mounted boilers; and
VAV applications.
Recommendation
Use only with Zone Valve Actuators.
