274-03112

Siemens' 274-03112 model is constructed as a two-way control valve assembly designed for effective flow regulation. The unit is equipped with an electro-hydraulic actuator, specifically the SKD62U model, which operates at a voltage of 24 VAC. This actuator is engineered to exert a nominal force of 225 lbf (1000 N) when the valve operates in a normally closed (NC) position. For a normally open (NO) setting, it can deliver a force of 258 lbf (1150 N).

The overall valve is designed with a size of 3/4 inches (20 mm), which makes it adaptable for multiple applications. Its flow coefficient is rated at 6.3 Cv, facilitating substantial fluid flow as required by system demands. Constructed from robust bronze, the body of the valve ensures longevity and resilience in operation, while stainless steel is used for the trim material, contributing to its durability.

This assembly operates effectively within an enclosure rated NEMA 1, which indicates suitability for indoor installation. The input voltage frequency is rated for 50/60 Hz, making this unit versatile in various settings. Leakage is kept to a minimum with adherence to ANSI Leakage Class IV standards, allowing only 0.01% of the Cv to leak, which is ideal for maintaining system integrity. The actuator housing is crafted from die-cast aluminum, enhancing its strength and reliability in operational conditions.
