Siemens S55180-A153 Pressure Independent Control Series SSD Electronic Valve Actuators

Siemens S55180-A153 Pressure Independent Control Series SSD Electronic Valve Actuators,
require a 24 Vac power supply and receive
a floating control signal (SSD131…) or a proportional 0 to
10 Vdc signal (SSD161S…) to control a valve. The 0 to
10V SSD161S… actuator also accepts a 24 Vdc power
supply.
These actuators are designed to work with 1/2- to
1-1/4-inch Pressure Independent Control Series Valves
with a 1/5-inch (5 mm), or 7/32-inch (5.5 mm) stroke and a
threaded valve bonnet that fits the actuator.
Features
● Modulating SSD actuators include position feedback
and equal percentage flow characteristic capabilities
● LED indicators for position, operating status, and
actuator motion on all actuators
● Modulating actuators have DIP switches to select
direct or reverse acting, equal percentage or linear flow
characteristic, and fail up or fail down (SSD161S.25DU
only)
● Floating fail-safe actuator (SSD131.29U) has DIP switch
for fail up or fail down
● Nominal force >67 lbs (300 N)
● Floating or 0 to 10 Vdc control
SSD Series fail-safe and fail-in-place
Electronic Valve Actuator
● Fail-safe and fail-in-place variants
● Automatic stroke calibration on the SSD161S…
● Manual override
● UL listed for plenum installation
● Removeable terminal block and 1/2″ threaded conduit
adapter connections
● Low noise level (<30dB)
Applications
For use in heating and cooling HVAC applications with
Pressure Independent Control valves. They can be used
in chilled/hot water applications or in water-glycol solutions
up to 50% in closed loop systems.
