3. Pre-Installation Checklist
Inspect the DCT18 Electric Float Level Control Valve for any visible damage during transport or storage, paying attention to the main diaphragm housing, solenoid pilot, and external float arm integrity.
Check that the valve type, size, pressure rating, and solenoid voltage match the system requirements.
Verify that the valve interior and pilot line strainers are clean and free from debris.
Confirm that the mating pipeline flanges are properly aligned (parallel and concentric) and free from burrs or sharp edges.
Ensure the external float switch is correctly installed at the required level inside the reservoir before wiring the valve.
4. Installation Procedure
Positioning: Install the DCT18 Electric Float Level Control Valve ensuring the flow direction adheres to the arrow cast on the body.
The main valve is typically installed outside the reservoir, connected to the solenoid pilot which receives the electrical command.
Use the appropriate gaskets suitable for the medium and operating conditions.
