The 276-05971 part by Siemens represents a globe valve integrated with an actuator. This setup is ideal for applications requiring regulated fluid dynamics. The valve measures 3 inches (80 mm) in size, with a flow coefficient of 100 Cv, equivalent to Kvs 86. It is constructed from cast iron for strength and durability and conforms to ANSI Class 125 body rating standards. The internal trim is made of stainless steel, enhancing its resistance to corrosion.

In terms of operation, this globe valve features a normally closed design with an equal percentage flow characteristic, allowing for consistent performance under varying conditions. It has a stem travel or stroke length of 3/4 inch (20 mm), providing adequate movement for adjusting flow. The actuator type is electro-hydraulic with a spring return mechanism, which ensures the valve returns to its closed position when not activated.

The assembly operates on 24 V AC electrical power and supports a control signal with a 3-position floating arrangement. For effective operation, the actuator exerts a nominal force of 225 lbf (1,000 N) when controlling the normally closed port and 258 lbf (1,150 N) for the normally open port. This unit exemplifies a reliable solution for systems requiring efficient flow management.
