Maintenance Tips
-
Regular Operation Checks:
-
Ensure that the valve operates smoothly and without leaks. The flow through the valve should be consistent and meet system requirements.
-
Visual Inspections:
-
Inspect the valve and surrounding pipes for any signs of leaks, corrosion, or physical damage.
-
Check the valve for any buildup of debris or sediment that could impair its performance.
-
Flow Measurement:
-
Regularly check that the flow measurement remains accurate and within system specifications. If there are significant deviations, the valve may need recalibration or servicing.
-
Tamper-Resistant Memory Stop:
-
Ensure that the tamper-resistant memory stop is intact and properly set to preserve system balance. Avoid adjustments unless necessary, as it could affect the performance.
-
Pressure and Temperature Monitoring:
-
Regularly check system pressure and temperature to ensure they are within the designed parameters. Incorrect pressure or temperature could indicate issues with the valve or the system.
-
Annual Professional Inspection:
-
Schedule a professional inspection at least once a year to verify that the valve and entire system are working efficiently. The technician should check for proper calibration, tight connections, and overall system balance.
