I. Preparations
Inspect the ductile iron gate valve for any damage.
Clean impurities and debris from both the interior and exterior of the valve.
Prepare necessary tools and materials (e.g., bolts, gaskets, sealant).
II. Installation Position Selection
Install the valve vertically or near-vertically on the pipeline.
Choose a location accessible for operation and maintenance.
Position the valve upstream with a drain port installed.
III. Installation Steps
Measure pipeline diameter and valve dimensions to ensure compatibility.
Mount flanges on both sides of the valve, placing gaskets between flanges.
Secure bolts and tighten to achieve a leak-proof connection.
After installation, close the drain port and valve.
Open the pipeline valve to test normal operation.
IV. Precautions
Avoid pipeline bending or stretching during installation.
Ensure sealing performance to prevent leakage.
Operate the valve with moderate force to avoid damage.
Regularly inspect valve performance and address issues promptly.
