291-05950

The Siemens 291-05950 globe control valve assembly plays a critical role in managing the flow in various systems. Designed with a diameter of 2-1/2 inches (65 mm), this component integrates seamlessly into industrial setups. The actuator model SKB62U is employed for this assembly, providing reliable actuation capabilities.

This valve operates specifically in a normally closed (NC) configuration, ensuring that the flow is effectively controlled according to system needs. With a flow characteristic described as equal percentage, the valve facilitates consistent flow regulation across its operational range. The trim is constructed from bronze, ensuring durability, while the body is made of robust cast iron, providing strength and resistance to wear.

For sealing, the design incorporates normal duty packing, which utilizes double EPDM O-rings, ensuring minimal leakage. The valve is rated for ANSI Class 250, making it suitable for high-pressure applications. Operationally, it works within a voltage range of 24 Vac with a tolerance of ±20%, and it accepts frequencies of either 50 or 60 Hz. The assembly also has a power consumption rating of 18 VA or 12 W, suitable for efficient performance.

Control signals can be inputted as either 0 to 10 Volts DC or 4 to 20 milliamps, providing flexibility for system integration. The actuator is designed to function within an operating temperature range of -15°C to 55°C, allowing it to perform in diverse environmental conditions. The Siemens 291-05950 globe control valve assembly thus meets essential requirements for varied applications in industrial settings.
