The Delta Control Products ST125-2-8 is a 1.25-inch, two-way Soft Touch valve designed for precise fluid control in HVAC systems. With a flow coefficient (Cv) of 8, this valve ensures efficient modulation of flow rates. The Soft Touch series incorporates a characterized ball design, providing high rangeability and equal percentage flow characteristics, effectively combining the performance of globe valves with the economy of ball valves. This design makes the ST125-2-8 ideal for automatic temperature control applications involving hot or chilled water. The valve is compatible with various electric actuators, including on/off, floating, and modulating control models, available in both spring return and non-spring return styles.
