3pc Flange Ball Valve With Mounting Pad

Our 3pc Flange Ball Valve with Mounting Pads are designed for direct actuator mounting and in-line maintenance. The main body is constructed from 304 or 316L stainless steel (cast steel is available for specific applications), featuring a bolted three-piece valve body structure and a high platform design compliant with ISO 5211 standards. It supports pneumatic/electric automation control and conforms to GB (Chinese National Standard), ANSI (American Standard), and DIN (German Standard) flange standards. A comprehensive quality control system ensures consistent performance across all production batches.

Core Structural Advantages

1. Three-Piece Detachable Structure

- Composed of a left valve body, a right valve body, and a middle valve body (including a ball core and stem assembly), secured with bolts.

- Online maintenance is possible without completely disassembling the valve from the pipeline. Simply loosen the bolts, remove the middle valve body, and quickly remove the ball core, seals, and other internal components for easy cleaning, maintenance, and replacement of vulnerable parts.

- Distributed stress distribution enhances the overall strength of the valve body, making it suitable for medium and high-pressure pipeline operation and effectively preventing valve body deformation and leakage.

- Reduces downtime for maintenance and lowers maintenance costs, making it particularly suitable for complex operating conditions requiring frequent maintenance.

2. High-Platform Stem Structure Compliant with ISO 5211 Standard

- Integrated high-platform top design fully complies with ISO 5211 standards, allowing direct installation of pneumatic/electric actuators without additional supports.

- The 3-piece Flange Ball Valve with Mounting Pad features a bottom-mounted stem structure and a dual-disc spring automatic packing compression design, optimizing stem sealing performance and preventing stem ejection in the event of abnormal pressure increases in the valve chamber, thus enhancing operational safety.

- Some models are equipped with an anti-static device to effectively release static electricity and prevent safety hazards caused by static buildup, making it suitable for flammable and explosive media applications.

- upports automatic control and remote operation, improving operational efficiency in assembly line production and unattended scenarios.

Sealing Materials and Performance

1. Polytetrafluoroethylene (PTFE): Strong corrosion resistance, excellent sealing effect, temperature range -29℃ to +150℃, low cost, suitable for normal temperature, pressure, and particulate-free media conditions, the most widely used, and can achieve bidirectional zero-leakage sealing.

2. Polyphenylene Sulfide (PPL): 3pc Flange Ball Valve with Mounting Pad, superior high temperature resistance and wear resistance, temperature resistance up to -29℃ to +300℃, suitable for high temperature, high pressure, and media containing slight particles, suitable for complex industrial conditions such as petroleum and chemical industries, stable sealing, and long service life.

3. Reinforced Polytetrafluoroethylene (RPTFE): Optimized and reinforced based on PTFE, it combines corrosion resistance and wear resistance, making it suitable for various conventional and mildly complex operating conditions, further enhancing sealing reliability.

Technical Parameters

FAQs

Q: What standards are followed for the inspection of the three-piece high-platform flanged ball valve? Which performance indicators are ensured to meet the standards?

A: The three-piece high-platform flanged ball valve strictly follows the GB/T-13927 and API 598 standards for inspection. Before leaving the factory, each valve undergoes strict pressure tests (water pressure and air pressure), dimensional accuracy tests, sealing performance tests, and appearance inspections. These tests ensure that the core performance indicators such as pressure bearing capacity, sealing performance, and dimensional accuracy meet the standards, and unqualified products are strictly prohibited from leaving the factory.

Q: Can I quickly buy suitable accessories if the seal ring of the three-piece high-platform flanged ball valve is damaged?

A: Yes. As a source manufacturer, Diye maintains a long-term stock of original compatible seal rings and various accessories (such as bolts and valve stems). We can deliver the goods quickly to meet your accessory replacement needs, reduce equipment downtime losses, and provide free technical guidance on replacement to ensure smooth and efficient replacement.

Q: What are the optional main materials for the valve body, ball core, and valve stem of the three-piece high-platform flanged ball valve? How to select the material?

A: The core optional main materials include three types: 304 stainless steel, 316L stainless steel, and carbon steel. The selection reference is as follows: ① 304 stainless steel: suitable for conventional water, oil, gas, and weak acid-base non-strong corrosion working conditions, with outstanding cost performance, suitable for ordinary industrial and civil pipelines; ② 316L stainless steel: added with molybdenum element, which has stronger corrosion resistance and oxidation resistance, suitable for complex working conditions such as strong acid-base, seawater, and chemical solvents, and is suitable for high-end scenarios such as petroleum and pharmaceuticals; ③ Carbon steel: high structural strength and excellent pressure-bearing performance, suitable for high-pressure, non-corrosive working conditions and heavy-load scenarios. All materials are produced by Diye's original factory and can be customized according to needs.
