277-05971

The 277-05971 from Siemens is a globe control valve assembly engineered for efficient fluid regulation. It is structured with a nominal diameter of 3 inches (80 mm), allowing it to effectively manage substantial flow volumes. The valve's outstanding flow coefficient is rated at 100 Cv, indicating its capability for performance in demanding environments.

This assembly utilizes a pneumatic actuator with the model number 599-01050, which does not include a positioner. It operates by means of a spring mechanism and has a nominal stroke length of 3/4 inches (20 mm). Designed to mount in a NEMA 1 enclosure, the actuator is optimized for standard installations while offering durability and protection from typical industrial conditions.

The control signal for this valve operates within a specified range of 3 to 8 psi, providing users with adequate operational flexibility. This globe valve features stainless steel as the trim material, which ensures longevity and resistance to corrosion in various media.

Connection with the piping system is accomplished via flanged connections, providing a secure fitting that enhances installation reliability. The valve assembly is rated according to ANSI Class 125, emphasizing its suitability for standard pressure applications. In a fail-safe situation, this valve will default to a normally closed position, thereby improving safety during power failures or system malfunctions.
