The Siemens 291-03188 globe valve assembly is engineered to provide reliable flow regulation in diverse environments. With its operational size set at 2 inches, this component uses internal thread connections on both ends to ensure secure integration into piping systems. The valve operates on a nominal voltage of 24 VAC.

A notable feature is its integrated electro-hydraulic actuator, which facilitates precise control over the valve’s operation. This actuator responds to a proportional control signal, accepting inputs of either 0 to 10 Volts DC or 4 to 20 milliamps, thereby offering adaptable communication with automation systems.

Designed with spring return fail-safe mechanisms, the valve ensures secure closure in case of power loss, enhancing its reliability in critical applications. It is built with brass trim and a stainless steel stem, combining durability with effective performance.

The valve's port configuration is structured as a 2-way normally closed type. Compatibility with various media includes steam, saturated steam, water, and anti-freeze solutions, making it versatile across different functions. The assembly operates within an ambient temperature range of -15°C to 55°C, and it is capable of managing media temperatures from a minimum of -7°C up to a maximum of 120°C.
