291-03186

The Siemens 291-03186 assembly serves as a control valve paired with an actuator, designed for reliable fluid regulation tasks in various environments. With a flow coefficient of 16 Cv, this valve performs efficiently under standard conditions. It is rated for an input voltage of 24 Vac, allowing for a tolerance of ±20%, suitable for most operational contexts.

Operating within a frequency range of 50/60 Hz, the assembly is built to endure environmental factors. It features an enclosure rating of NEMA 1, with an option for NEMA 3R when equipped with a weather shield accessory. The ambient operating temperature ranges from -15°C to 55°C, accommodating diverse settings.

The valve body is designed to the rigorous ANSI Class 250 standard, ensuring high reliability in high-pressure scenarios. Constructed from bronze, its trim material is brass, which aids in its longevity and efficiency. The valve operates as a 2-way normally closed unit, providing an equal percentage flow pattern to maintain accurate regulation.

In terms of operational specifics, the assembly consumes 17 VA of power, with a control signal capability utilizing 0-10 Volts DC or 4-20 mA input. At its core, the assembly incorporates the SKB62U electronic actuator featuring a spring return design, which empowers the valve to return to its default position promptly during operation interruptions.
