Zone Valves
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
• Order separately or with an actuator as a
complete assembly
Two-Way NPT Zone Valve.
Three-Way Sweat Zone Valve.
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.
