274-03187

The Siemens 274-03187 globe valve assembly is engineered to manage various media, including saturated steam and water mixed with antifreeze. With a valve size of 1-1/2 inches, it is classified as a 2-way normally-closed unit. This design is particularly beneficial for applications where flow control is essential.

The assembly features an integrated electro-hydraulic actuator, which facilitates smooth operation. To enhance safety and reliability, it incorporates a spring return fail-safe mechanism, ensuring that the valve defaults to a closed position during power loss. The valve allows a stroke length of 3/4 inches and is configured to offer an equal percentage flow characteristic for precise control over the medium.

With a flow capacity of 25 Cv, this valve is quite effective in various systems. The medium temperature range extends from -7°C to 120°C, making it versatile across a range of applications. For connection purposes, it utilizes an internal thread interface at both ends, allowing for secure integration into piping systems. The actuator operates on a nominal voltage of 24 VAC and has a power consumption rate of 18 VA. Control signals can be proportional, ranging from 0 to 10 Volts DC or 4 to 20 milliamps, allowing for adaptability to different control systems. The trim material is crafted from brass, enhancing durability in challenging environments.
