Siemens 257-02039 1/2" Valve Assembly FxUM 2" Pneumatic Actuator 2.5Cv No 3-8 PSI

The Siemens 257-02039 2" Pneumatic Actuator with 1/2" Valve Assembly FxUM is a flexible device manufactured for detailed regulation in the HVAC devices. This actuator consists of a valve assembly with flow coefficient of 2. 5CV and its low range of 3-8 PSI of the spring is also adjustable to ensure that the air distribution is well controlled. It works well over humidity range of 0-100% RH and therefore is appropriate for different conditions. Designed for use in HVAC applications, this actuator helps in controlling the temperature and air flow by accurately controlling the valve seating.
