274-05991

The Siemens part number 274-05991 is an advanced globe valve assembly that excels in controlling flow in various industrial systems. Crafted with a body size of 3 inches (80 mm), it caters to applications demanding precise regulation. Its flow coefficient rating of 100 Cv denotes its capability to manage significant flow volumes efficiently.

The valve operates on a voltage rating of 24 Vac, with a tolerance of -20% to +30%, making it versatile across different setups. It functions effectively with a frequency of either 50 or 60 Hz. Designed for use in demanding environments, the valve’s enclosure is rated NEMA 1, providing protection against dust and indirect water exposure.

This globe valve assembly can maintain ambient operating temperatures from -15°C to 50°C. It allows media temperatures between -25°C and 150°C; however, when operating below 0°C, a stem heater is required for optimal functionality. Constructed from robust cast iron, the valve body adheres to ANSI Class 125 ratings, ensuring structural integrity. The bronze trim enhances the valve’s lifespan against corrosion and wear.

In terms of operation, the valve employs a 2-way normally closed configuration, designed to provide equal percentage flow, which guarantees effective modulation across varying flow rates. The system's power consumption is rated at 17 VA with a control signal of 12 W, compatible with either 0-10 Volts DC or 4-20 mA inputs. The SKD62U electronic actuator features a spring return mechanism, ensuring reliable closure and efficient performance. Overall, the 274-05991 globe valve assembly combines durability, flexibility, and precision in a single unit.
