Product Overview
The Siemens SSP31 Electromotoric Valve Actuator is a precision-engineered electric actuator designed for the reliable operation of control and shut-off valves in industrial heating, ventilation, and hydronic systems. As part of Siemens’ renowned SSP series, this actuator delivers consistent linear or rotary stroke positioning through a synchronous motor drive mechanism, ensuring accurate valve modulation in response to analog or three-position control signals. The SSP31 is specifically engineered to interface seamlessly with Siemens valve bodies and compatible third-party valve assemblies, providing dependable actuation for water and steam control applications. Its compact, robust housing and maintenance-free gear train make it an ideal choice for building automation, district heating networks, and industrial process control loops where precise valve positioning and long service life are critical.
