Maintenance Tips
-
Inspect Regularly: Check for leaks, corrosion, or signs of wear. Ensure fittings are secure and free from debris.
-
Protect During Soldering: Always close the valve before soldering. Avoid direct heat to prevent internal damage—use low-temp solder only.
-
Flush System Before Use: Before installation, flush the piping system to clear out particles that might clog the valve.
-
Adjust Flow Precisely: Use the calibrated memory stop to accurately set and reset flow without re-reading the dial.
-
Monitor Pressure: Use pressure taps for flow verification. Always ensure gauges are appropriate for system pressure.
-
Avoid Excessive Force: Do not overtighten during installation or adjustment. Use proper tools for valve control.
-
Store Properly: If not in use, store in a dry, temperature-controlled area to prevent rust or degradation.
