274-05950

The Siemens 274-05950 control valve and actuator assembly is constructed for robust performance across a range of operational scenarios. Serving as a two-way valve, it functions in a normally closed capacity with an equal percentage flow pattern. This design allows for efficient control in fluid management applications. The valve features a flow coefficient of 63 Cv, ensuring effective regulation of fluid flow.

The assembly operates at a nominal voltage of 24 Vac, with a variation tolerance of -20% to +30%. It is compatible with input frequencies of 50/60 Hz, making it adaptable for various electrical systems. The NEMA 1 enclosure rating qualifies it for light indoor applications, while an optional weather shield accessory allows for a NEMA 3R rating, enhancing outdoor usability.

Constructed from cast iron, the valve body is rated ANSI Class 250, ensuring adequate strength and durability under pressure. Its bronze trim enhances reliability and resistance to wear over time. The ambient operating temperature ranges from -15°C to 50°C, allowing function in diverse climate conditions. Media can reach temperatures between -25 and 150°C, although temperatures below 0°C will require the installation of a stem heater.

Power consumption is rated at 17 VA/12 W, with an actuator input that accepts control signals of 0-10 Volts DC or 4-20 mA. The assembly includes the SKD62U electronic actuator with a spring return feature, ensuring secure operation and integrity during actuation processes.
