Powermite
MZ Series Globe
Powermite MZ Series
SSB61U Electronic Valve Actuator.
Description
The Powermite SSB61U Electronic Valve Actuator
requires a 24 Vac supply and receives a 0 to 10 Vdc
control signal to proportionally control a valve. This
actuator is designed to work with Powermite MZ Series
Valves with a 7/32-inch (5.5 mm) stroke and a threaded
valve bonnet that ts the actuator.
Features
• UL-listed for plenum installations
• Direct-coupled for installation without tools
• Close-off up to 70 psi on 1/2-inch valve
• Non-spring return
• Manual override
• Visual position indication
• Orderable as an actuator only or as a complete
valve/actuator assembly
Applications
The Powermite SSB61U Electronic Valve Actuator is for
use in heating and cooling HVAC applications with
Powermite Valves that need 45 lbf. (200 N)
of nominal force.
Recommendation:
Use only with the MZ Series valve bodies.
