Introducing the Siemens VXF42.125-250 3-port valve, the ideal solution for controlling the flow of medium in industrial settings. With a stroke of 20 mm for DN80 and 40 mm for DN100, this valve is capable of handling a wide range of flow rates.
The leakage rate of the valve is an impressive 0…0.02% of the kvs value, ensuring minimal waste and maximum efficiency. Additionally, the leakage rate bypass ranges from 0.5...2% of the kvs-value, providing greater control over the flow of the medium.
With a DN of 125 and a kvs of 250 m³/h, this valve is built to handle high-volume flow rates with ease. The valve's medium temperature range of -10…150 °C makes it suitable for use in a variety of applications.
The valve's through-port characteristic ensures equal percentage, and the through-port kvs 250/400 linear, while the bypass is linear. The rangeability of the valve is also impressive, with DN 15...25: >50 and DN 32...150: >100.
The permissible operating pressure for the Siemens VXF42.125-250 3-port valve is 1600 kPa, making it a reliable and durable solution for even the most demanding environments. The valve body is made of cast iron EN-GJL-250, while the inside set is made of CrNi steel/brass for DN40 or less and CrNi steel/bronze for DN50 or more.
With a PN class of PN 16, this valve is an excellent choice for anyone seeking a high-quality, reliable, and efficient solution for industrial flow control. The Siemens VXF42.125-250 3-port valve is a top-of-the-line product that is sure to exceed your expectations.
