274-05980

Siemens presents the part number 274-05980, a control valve assembly tailored for reliable performance in fluid control systems. This unit integrates an SKD62U actuator and operates at a voltage rating of 24 Vac, ensuring compatibility with standard systems while accommodating a frequency of 50/60 Hz. The valve size is 2-1/2 inches, appropriate for various industrial applications.

Constructed from durable materials, the actuator housing is made of die-cast aluminum, paired with a robust cast iron valve body and bronze trim for enhanced reliability during operation. It is designed to operate efficiently within an ambient temperature range of -15°C to 55°C and can handle medium temperatures up to 120°C. This versatility ensures effectiveness across differing industrial environments.

The control valve features a proportional signal control type, allowing for precise modulation through inputs of 0 to 10 Volts DC or 4 to 20 mA. For added security, this assembly has an ANSI Class IV leakage rating, indicating that it allows for a mere 0.01% of the Cv to leak, enhancing operational efficiency and minimizing waste. A noteworthy attribute is its nominal force capacity, with 225 lbf at 0% and 258 lbf at 100%, approximating 1000N/1150N, which indicates its ability to handle substantial loads. Furthermore, its flow coefficient is rated at 63/54 Cv, confirming its efficiency in fluid handling, making the 274-05980 a reliable choice for demanding control applications.
