Description
Siemens 656-833 Replacement Actuator is a high performance actuator used for high accuracy control in HVAC systems. It operates at 3-8 PSI on a 1/4″ NPT connection so it’s easy to integrate into an existing system. It has a Flow Coefficient of 5 Cv, which is an efficient fluid control and adaptable for different applications. This actuator takes a 4-20 mA signal input, facilitating easy mating with most control systems. The Siemens 656-833 actuator is constructed from durable aluminum and is robust and reliable, and therefore suitable for a variety of operating environments. It works over a temperature range of 32°F to 122°F, which is typical operational temperature.
