276-05981

The Siemens 276-05981 is a specialized control valve assembly tailored for precision in fluid regulation. This unit operates with a voltage rating of 24 Vac, maintaining a tolerance of ±20%. The actuator model SKD82.51U drives its functionality effectively, delivering performance aligned with various system requirements.

Designed to handle ambient temperatures ranging from -15°C to 55°C, this control valve is suited for diverse operational environments. It can manage media temperature as high as 120°C, making it versatile for applications requiring temperature regulation. The control signal type is a 3-position floating mechanism complemented by a spring return feature, allowing stable operation even under changing conditions.

The unit’s construction combines durability and efficiency; the actuator housing is die-cast aluminum, while the valve body consists of sturdy cast iron, ensuring long-lasting reliability. The trim incorporates bronze material, contributing to the assembly's overall robustness. It has a leakage rating of ANSI Class IV, which guarantees minimal leakage at just 0.01% of the Cv.

Operating with a nominal force of 225 lbf at 0% and 258 lbf at 100%, the valve assembly delivers adequate power based on the conditions set for its application. The flow coefficients of 100/86 Cv indicate its capability to manage different flow scenarios efficiently. Overall, the Siemens 276-05981 control valve assembly is a vital component for achieving precise control in various industrial processes.
