274-03170

The Siemens 274-03170, part of the Flowrite 599 Series, is specifically designed as a globe valve assembly. This assembly is suited for a variety of mediums, including saturated steam, plain water, and water containing antifreeze. It features a valve size of 2 inches and offers a flow capacity of 40 Cv, ensuring efficient fluid regulation. Operating in a 2-way normally-open configuration, the assembly permits straightforward control of the fluid passage.

Incorporating an electro-hydraulic actuator, the assembly ensures precise control and responsiveness. It operates at a nominal voltage of 24 VAC. Furthermore, the actuator features a spring return fail-safe mechanism, enhancing operational security by reverting to a safe position in the event of power loss.

With a valve stroke length of 3/4 inches, the flowing system demonstrates an equal percentage flow characteristic. This feature provides a predictable flow dynamic across varying control signals. The apparatus accepts proportional control signals ranging from 0 to 10 volts DC or 4 to 20 milliamps, accommodating various control strategies. The internal thread connection type allows for straightforward installation and integration into existing systems.

The unit is built to operate effectively within a temperature range of -7°C to 121°C, making it adaptable for different operational conditions. Brass is utilized for the trim material, ensuring robustness and durability. The assembly has a power consumption rate of 18 VA, maintaining efficient energy usage in control applications.
