The CHTF series regulators are axial-flow, indirect-acting pressure regulators. Equipped with a pilot featuring a pressure-stabilizing structure and combined with the main valve’s axial-flow design, this series offers a higher flow coefficient and more stable performance, making it especially suitable for high/medium-pressure, high-flow regulator skids/stations.
