Manufactured from high-strength, corrosion-resistant materials and built with a robust two-piece bolted body, the DBL10 Full Bore Ball Valve 2 Pieces is designed to withstand continuous high pressure and challenging operating environments. The two-piece construction offers significant maintenance advantages, allowing the valve body to be easily disassembled for cleaning, repair, and swift replacement of the seals and ball without removing the entire valve ends from the line.
The DBL10 Full Bore Ball Valve 2 Pieces is ideally suited for applications in bulk fluid transfer, aggressive chemical lines, fuel storage terminals, and any system where swift operation, ease of inspection, and unrestricted fluid passage are essential. Its superior flow characteristics and maintainability make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term critical process control.
In summary, the DBL10 Full Bore Ball Valve 2 Pieces offers an optimal combination of hydraulic performance, rapid isolation, and cost-effective maintenance access. With its full-bore design, durable two-piece construction, and reliable quarter-turn action, this unit stands as a trusted solution for modern fluid control and process reliability requirements worldwide.
1. General Information
The DBL10 Full Bore Ball Valve 2 Pieces is designed for on/off service requiring rapid closure and minimal pressure loss. Proper installation is essential to guarantee safe operation, long service life, and efficient, leak-free performance.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with pressurized and potentially hazardous fluid systems.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and drained before attempting to install the DBL10 Full Bore Ball Valve 2 Pieces.
3. Pre-Installation Checklist
Inspect the DBL10 Full Bore Ball Valve 2 Pieces for any visible damage during transport or storage, paying attention to the flange faces and handle mechanism.
Check that the valve type, size, and pressure rating match the system requirements.
Verify that the valve ball and interior 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 valve handle has sufficient clearance for a full 90-degree turn in both the open and closed positions.
4. Installation Procedure
Positioning: Install the DBL10 Full Bore Ball Valve 2 Pieces ensuring the flow direction aligns with the valve’s through-bore. The valve is typically bi-directional and can be installed in horizontal or vertical pipelines.
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. This ensures even compression of the gasket and prevents stress on the valve body.
5. Post-Installation
Slowly reintroduce fluid and pressurize the system, checking for leaks around the flange connections and the stem/packing area. If leakage is detected, depressurize the system immediately and re-tighten the bolts following the cross-pattern sequence. Record the installation details, date, and final bolt torques for documentation purposes.
Proper maintenance extends the service life of the DBL10 Full Bore Ball Valve 2 Pieces and ensures reliable shut-off and high flow capacity. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DBL10 Full Bore Ball Valve 2 Pieces exterior regularly (e.g., monthly) for signs of external leakage, especially around the body joint and stem packing. Operate the valve (full open to full closed) periodically to prevent buildup of media around the ball and seat seals.
2. Inspection Schedule
Monthly, check the valve exterior for external leaks around the flange connections and stem packing area.
Quarterly, check the functionality of the locking device (if applicable) and the ease of the quarter-turn operation.
Annually, perform a detailed inspection of the seals and ball surfaces by partially disassembling the valve at the two-piece joint (after isolation and draining).
3. Lubrication
The DBL10 Full Bore Ball Valve 2 Pieces generally utilizes self-lubricating PTFE/TFM seats and seals. The stem packing should be inspected, and adjusted or replaced if leakage is present; external lubrication is typically not required for the ball mechanism.
4. Seal and Gasket Replacement
Replace the main body gasket (at the two-piece joint) and the stem seals immediately if external leakage is observed. The ball seats 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 requiring disassembly.
5. Cleaning
Keep the exterior of the DBL10 Full Bore Ball Valve 2 Pieces clean to prevent surface corrosion. If media buildup is suspected, the valve can be cleaned internally by flushing the line or by opening the body joint (when isolated and safe).
6. Storage and Spare Parts
Store spare parts (gaskets, replacement seats, packing) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes. Maintain a detailed record of all inspections, internal part replacements, and repairs performed on the DBL10 Full Bore Ball Valve 2 Pieces unit.

Frequently Asked Questions about the DBL10?
What are the main advantages of this valve?
The DBL10 Full Bore Ball Valve 2 Pieces offers superior flow efficiency by virtually eliminating pressure drop (full bore), combined with the simplicity of rapid quarter-turn isolation and easy inline maintenance thanks to its two-piece body design.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What does the "Full Bore" designation mean for the DBL10 Full Bore Ball Valve 2 Pieces?
“Full Bore” means the inner diameter of the ball’s bore is equal to the internal diameter of the connected piping. This ensures minimal turbulence and zero hydraulic resistance, making it suitable for pigging and viscous fluid transfer.
How does the "2 Pieces" construction simplify valve maintenance?
The two-piece construction is beneficial because it allows the main seals (seats) and the ball to be accessed and replaced by removing just the body section bolted to the end piece, without needing to detach the entire valve ends from the pipeline flanges.
Is the DBL10 Full Bore Ball Valve 2 Pieces suitable for throttling (flow regulation)?
No. While technically possible, the DBL10 Full Bore Ball Valve 2 Pieces is generally designed for on/off isolation service. Using it for throttling can lead to rapid wear and erosion of the seats and ball, compromising its crucial bubble-tight sealing capability.
