Description
The SSA/SSP Electronic Valve Actuator requires a 24 Vac power
supply and receives a 0 to 10 Vdc signal or a oating control signal
to control a valve. This actuator is designed to work with Zone
Control Valves with a 1/10-inch (2.5 mm) stroke and a threaded
valve bonnet that ts the actuator.
Features
• UL listed for plenum installations
• Direct-coupled installation without tools
• Manual Override with hex wrench
• Visual position indication
Applications
The SSA/SSP Electronic Valve Actuators are for use with heating and
cooling HVAC applications with Zone Valves.
