274-05951

The Siemens 274-05951 assembly serves as a robust control valve and actuator system. It features a flow coefficient of 100 Cv, making it suitable for applications that require significant flow regulation. Designed for a standard nominal valve size of 3 inches (80 mm), this unit supports efficient fluid management across various operational contexts.

This control assembly functions on a voltage rating of 24 Vac and can tolerate variations from -20% to +30%. It can operate on input frequencies conforming to either 50 or 60 Hz. The assembly is housed within a NEMA 1 rated enclosure, providing adequate protection in standard operating environments while maintaining accessibility. The operational temperature range extends from -15°C to 50°C, while media temperatures compatible with the assembly range from -25°C to 150°C.

The valve is constructed from sturdy cast iron and is rated according to ANSI Class 250, ensuring durability and leak-free performance. It employs a bronze trim for enhanced resilience against wear. As a 2-way, normally closed valve, it employs an equal percentage flow pattern. The actuator integrated into this assembly is the SKD62U electronic model, featuring a spring return mechanism for reliable closure. Power consumption is rated at 17 VA or 12 Watts, with control signals expressed through either 0-10 Volts DC or 4-20 mA input. Overall, this assembly is engineered for efficient and accurate control in a variety of applications.
