The DCT28 Traceable Butterfly Valve is a specialized isolation valve specifically engineered to provide reliable flow shut-off while offering precise, non-destructive location identification for buried assets. Designed to meet the stringent demands of modern infrastructure, this specialized valve ensures outstanding operational reliability, simplified maintenance planning, and long-term durability in municipal water mains.
At the core of the DCT28 Traceable Butterfly Valve is its integrated identification technology, often utilizing a passive RFID tag or a specific metallic signature embedded within the valve body. This feature allows utility crews to locate the exact position and depth of the valve underground using surface-level detection equipment, eliminating the guesswork and costly excavation associated with finding buried assets.
Manufactured from high-strength, corrosion-resistant materials (such as ductile iron) and built with a robust wafer or flanged body, the DCT28 Traceable Butterfly Valve is designed to withstand continuous system pressure and harsh burial environments. The valve provides dependable, bubble-tight shut-off via its resilient-seated disc, which is essential for isolating sections quickly during repair or leakage detection operations.
The DCT28 Traceable Butterfly Valve is ideally suited for applications in District Metering Areas (DMAs), underground valve chambers, and any water network where accurate asset mapping, leak response time, and the long-term integrity of concealed components are essential. Its combination of robust isolation and integrated location tracking makes it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for smart utility management.
In summary, the DCT28 Traceable Butterfly Valve offers an optimal combination of operational reliability, structural durability, and crucial non-intrusive localization capability. With its resilient disc sealing, corrosion-resistant materials, and focus on asset management, this unit stands as a trusted solution for modern fluid control and underground network requirements worldwide.
1. General Information
The DCT28 Traceable Butterfly Valve is designed for installation on pressurized pipelines, requiring accurate positioning and careful documentation of the integrated ID tag location. Proper installation is essential to guarantee reliable isolation and successful future tracing operations.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with buried pressurized pipelines and excavation safety.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and isolated before attempting to install the DCT28 Traceable Butterfly Valve.
3. Pre-Installation Checklist
Inspect the DCT28 Traceable Butterfly Valve for any visible damage during transport or storage, paying attention to the disc and integrated ID mechanism.
Check that the valve type, size, and pressure rating match the system requirements.
Verify that the valve interior and resilient seat 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.
Record the unique ID number of the valve and its exact GPS coordinates immediately prior to burial.
4. Installation Procedure
Positioning: Install the DCT28 Traceable Butterfly Valve ensuring the flow direction adheres to the arrow cast on the body.
The valve must be installed with the axis easily accessible for operation by T-key or actuator.
Use the appropriate gaskets suitable for the medium and operating conditions.
Align the valve precisely between the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps.
Handle the valve carefully to avoid damaging the internal tracing components.
5. Post-Installation
Slowly reintroduce fluid and pressurize the system, checking immediately for leaks around the flange connections.
If leakage is detected, depressurize the system immediately and re-tighten the bolts following the cross-pattern sequence.
Verify the valve location and ID tag function using the appropriate tracing equipment at grade level.
Record the installation details, GPS location, and final bolt torques for documentation purposes.
Proper maintenance extends the service life of the DCT28 Traceable Butterfly Valve and ensures reliable shut-off and continuous location capability. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DCT28 Traceable Butterfly Valve access point (valve box) regularly (e.g., quarterly) for water ingress or debris accumulation that could impede operation.
Test the valve’s trace capability annually using specialized location equipment to confirm the integrated tag remains functional and correctly identified.
2. Inspection Schedule
Monthly, check the valve box area for signs of external leakage.
Quarterly, check the ease of operation using the T-key; excessive torque required may signal disc binding.
Annually, perform a comprehensive inspection of the seating area by isolating and operating the valve, ensuring the tight shut-off integrity is maintained.
3. Lubrication
The internal stem bearings of the DCT28 Traceable Butterfly Valve should be inspected and lubricated (if necessary) according to the manufacturer’s specifications.
The operating nut should be kept clean to ensure smooth T-key engagement.
4. Seal and Gasket Replacement
Replace the flange gaskets and stem packing immediately if external leakage is observed.
The resilient seat should be replaced if internal leakage (flow when closed) is detected during a pressure test.
Always isolate the valve and fully depressurize and drain the line before attempting any maintenance work.
5. Cleaning
Keep the valve operating nut and access point clean to prevent dirt and debris from being introduced into the stem mechanism.
If the valve is excavated for repair, ensure the exterior coating and the area around the integrated ID tag are cleaned and inspected for damage before reburial.
6. Storage and Spare Parts
Store spare parts (gaskets, replacement seats, packing sets) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes.
Maintain a detailed record of all inspections, tracing tests, and repairs performed on the DCT28 Traceable Butterfly Valve unit.
