Part number 281-05982 from Siemens is a globe valve that includes a pneumatic actuator. The actuator model for this assembly is 599-01000, which supports reliable operation. The valve has a nominal size of 4 inches (100 mm) and is built with a flanged iron body complemented by brass trim for enhanced durability and performance. This design is suitable for various applications requiring efficient fluid control.

The assembly achieves a flow coefficient rating of 160 Cv, enabling effective flow regulation. It operates normally open (NO) in a 2-way configuration, allowing for direct flow management when engaged. The valve also features an equal percentage flow characteristic, which assists in maintaining consistent performance across different flow rates.

The actuator is factory-set within a spring range of 3 to 8 psi, and it features a close-off pressure of 40 psi (276 kPa) for better control under varying system conditions. It has an actuator stroke length of 1-1/2 inches (40 mm), ensuring a solid movement for precise operation. The assembly is rated to meet ANSI Class 125 standards for pressure, confirming its capability to handle significant operational demands.

Its enclosure is rated NEMA 1, indicating protection suitable for indoor environments where exposure to solid foreign objects is minimal. The 281-05982 assembly represents a reliable choice for applications needing accurate and durable fluid control solutions.
