The 274-06050 from Siemens is an integrated globe valve and actuator assembly, meticulously designed to provide reliable control in various fluid handling applications. This assembly features a valve with a size of 2-1/2 inches (65 mm). With a flow coefficient of 63 Cv (equivalent to 54 Kvs), it effectively manages flow rates as required.

The structure comprises a robust cast iron body rated to ANSI Class 125, ensuring durability and integrity in challenging environments. To withstand high-temperature conditions, the assembly includes stainless steel trim specifically designed for heat resistance.

The packing uses a combination of Teflon V-ring and EPDM O-ring, suitable for steam applications, which ensures a secure seal and minimizes leakages. In terms of operation, the valve is normally closed and exhibits a linear flow characteristic. The stem travel or stroke length is measured at 3/4 inches (20 mm), allowing for precise adjustments.

This globe valve assembly operates on a 24 V AC voltage and can receive a control signal of either 0 to 10 Volts DC or analog signals between 4 to 20 milliamps. The included actuator, an electro-hydraulic model known as SKD62U, functions with a spring return mechanism, enabling it to return to a default position when not activated. Overall, the 274-06050 is a well-engineered assembly that meets the demands of various control systems.
