Product Overview
Siemens SSC61 Actuator with DN25 3-Port Valve – Used, Light Wear
Presented here is a Siemens SSC61 value actuator powered by 24V AC or DC, supplied with a Siemens VXP459.25-6.3 three-port seat valve.
This is the kind of pairing designed to disappear into a mechanical room and do its work quietly, regulating flow day after day without demanding attention.
Product Condition
The actuator and valve are used and in good condition, showing very little visible wear based on visual inspection. Full functional testing was not performed; however, the assembly appears complete and intact.
Product Overview
Siemens is a long-established manufacturer of building automation and HVAC control equipment. The SSC61 actuator is commonly used for proportional valve control in hydronic heating and cooling systems.
Paired with a VXP459 series valve, this assembly supports precise flow regulation in closed-loop systems where stability and repeatability matter.
