279-05991

The Siemens 279-05991 valve assembly is a robust solution for various flow control needs. Constructed as a globe valve, it is designed with a flanged end connection, allowing for a secure and stable fit within piping systems. Weighing in at 141.9 lbs, it provides a substantial presence, indicating its durable construction.

This model features a nominal valve size of 3 inches with a stroke length of 3/4 inches, optimizing control during operation. The valve's port configuration adheres to a 2-way normally closed (N.C.) design, which supports efficient flow management in heating and cooling applications. An integral pneumatic actuator enhances the valve's operational capabilities, providing responsive action to control signals.

The valve is defined by its flow characteristic, rated as equal percentage, enabling consistent and accurate flow behavior over various operating conditions. Its flow capacity measures at 100 Cv, demonstrating significant efficiency in conveying media. This assembly is notably compatible with steam, saturated steam, and water - including water mixed with anti-freeze substances. The medium temperature range for operation extends from -7°C to 120°C, reinforcing its adaptability in diverse environments.

Materials used within the valve assembly include a stainless steel stem for strength and longevity, while the valve trim is crafted from bronze, which enhances resistance against corrosion. The combination of robust materials and thoughtful engineering makes the 279-05991 a reliable component for industrial applications needing effective flow regulation.
