291-05981

The Siemens 291-05981 is a globe control valve assembly engineered for precision control in fluid systems. It features a valve size of 3 inches (80 mm), making it capable of handling substantial flow rates. The valve operates with a flow coefficient of 100 Cv, indicating its efficiency in regulating flow. The action of this valve is normally open (NO), allowing for continuous flow until actuated otherwise.

Equipped with the SKB62U actuator, this assembly offers an equal percentage flow characteristic, enhancing its ability to adjust to varying conditions within the system. The trim consists of durable bronze, ensuring it withstands wear and corrosion. The packing type utilizes double EPDM O-rings for reliable sealing and durability.

This valve body is constructed from cast iron, which grants strength and longevity, with a rating of ANSI Class 125 for added reliability. Operating at a voltage rating of 24 Vac ±20%, it is suitable for various electrical environments. The device functions properly with a frequency input of 50/60 Hz and has a current consumption rated at 18 VA (12 W).

Control signals can be adjusted from 0 to 10 Volts DC or 4 to 20 milliamps, providing flexibility in integration with existing control systems. The actuator is rated for an operating temperature range from -15°C to 55°C, allowing it to perform effectively in a wide range of environmental conditions.
