274-03204

The Siemens part number 274-03204 functions as a three-way mixing control valve assembly, specifically engineered to enhance fluid handling in various applications. It integrates an electro-hydraulic actuator, designated as SKD62U, with a spring return feature that ensures reliable operation.

This valve operates effectively on a voltage supply of 24 Vac ±20%, managing inputs at frequencies of either 50 or 60 Hz. Its robust design includes an IP54 rating, providing protection against the ingress of dust and moisture, suitable for many operational environments.

In terms of functionality, the valve showcases a size of 1-1/4 inches (32 mm) and is equipped with a bronze/brass trim material, which enhances durability and resistance against wear. With a flow coefficient of 16 Cv, this assembly allows for efficient fluid conveyance while maintaining precise control.

The control signal for operation can range from 0 to 10 Vdc or 4 to 20 mA, ensuring compatibility with various control systems. The valve's flow characteristic is linear, promoting predictable performance throughout its operation.

For timing, the run time is specified at 120 seconds for the valve to fully open and 15 seconds for the spring-return close, enabling a responsive and efficient control feature that is essential in dynamic applications. Overall, this assembly represents a reliable choice for applications requiring accurate and efficient mixing of fluids.
