3PC Long Weld Ball Valve

The 3PC Long Weld Ball Valve is designed for harsh industrial conditions. Its three-piece split structure combined with an extended welded end provides a robust and leak-proof solution for long-distance pipelines. The floating ball seal design allows for easy operation, with quick opening and closing with a 90° rotation, effectively reducing downtime and improving operational efficiency.

As a leading manufacturer specializing in fluid control solutions, DIYE VALVE integrates advanced manufacturing technology and rigorous quality control to ensure superior performance, durability, and safety.

Core Structure and Material Advantages

1. Precision Casting Valve Body: The 3PC Long Weld Ball Valve is precision cast from high-quality stainless steel (preferably 304/316), ensuring uniform wall thickness and stable pressure resistance. The extended welding end features a standard butt-welding bevel for seamless connection to pipelines, eliminating the risk of media leakage. The three-piece structure supports online disassembly and maintenance without disassembling the entire valve or damaging the pipeline, significantly reducing subsequent maintenance costs and downtime.

2. High-Strength Internal Components: The ball and stem are precision machined from the same grade of stainless steel, offering wear and corrosion resistance, and preventing jamming, ensuring coaxiality during opening and closing and extending service life. The stem features an anti-blowout structure, combined with a floating ball/fixed ball sealing design, adaptable to different temperature, pressure, and media requirements. The sealing pair uses PTFE and reinforced PPL materials, ensuring reliable sealing performance.

3. Superior Sealing and Operational Performance: The welded connection structure offers high strength and excellent sealing performance, suitable for high-temperature, high-pressure, and zero-leakage scenarios. The 90° quarter-turn operation is precise and fast, and the light torque design reduces operator fatigue, making it suitable for frequent operation scenarios.

FAQs

Q: What are the pressure rating and sealing standards of the 3PC long welded ball valve?

A: Conventional pressure ratings: PN16/PN25/PN40/PN64. For sealing: PTFE soft seal (normal temperature applications), reinforced PPL seal (medium and high temperature applications), metal hard seal (high temperature, high pressure and wear-resistant applications), all achieving bidirectional zero leakage.

Q: What are the routine maintenance and warranty terms for the 3PC long welded ball valve?

A: Regularly inspect the welded joints and opening/closing flexibility in daily use; frequent lubrication is not required. Under normal operating conditions, a 12-18 months warranty period is provided. Non-artificially damaged parts will be repaired or replaced free of charge within the warranty period, and lifetime technical support and cost-price spare parts supply are available.
