291-03077

The 291-03077 is a high-temperature globe valve assembly developed by Siemens as part of the Flowrite 599 Series. This valve operates effectively within a temperature range of -7°C to 169°C, allowing it to handle various media such as steam, saturated steam, water, and water mixed with anti-freeze. The assembly has a nominal size of 1 inch and weighs 67 lbs, offering robust construction suitable for challenging environments.

Designed with internal thread connections, it is easily integrated into existing piping systems. The valve utilizes an electro-hydraulic actuator to provide reliable control, while its fail-safe mechanism operates via a spring return to ensure the valve returns to a safe position if power is lost.

The control signal input can accept proportional signals in the range of 0 to 10 volts DC or 4 to 20 milliamps, enhancing compatibility with various control systems. This versatility is crucial in precise control applications, allowing for smooth operation over a linear flow characteristic.

The assembly can manage a flow capacity of 10 Cv, making it effective in regulating fluid dynamics within a system. Both the valve trim and the stem are manufactured from stainless steel, adding to the valve's longevity and reliability under high-temperature conditions. The ambient operating temperature range extends from -15°C to 55°C, allowing for versatile use in a variety of environmental situations.
