3PC Threaded Ball Valve ISO5211

DIYE VALVE is a leading valve company in China, specializing in the wholesale and large-scale production of three-piece threaded ball valves. The 3PC Threaded Ball Valve ISO5211 features a three-piece split structure (left, middle, and right body) with internal threaded connections at both ends. The standard ISO 5211 high-platform design allows for direct installation of pneumatic or electric actuators for remote automated control.

This valve is widely used in clean piping systems in chemical, petroleum, food, pharmaceutical, and water treatment industries, fully meeting the stringent requirements for long-term stable industrial operation.

Core Structure and Process Advantages

1. Precision Manufacturing Process: The valve body is manufactured using precision investment casting, resulting in a uniform structure, consistent wall thickness, and a smooth, pinhole-free surface. Subsequent CNC precision machining ensures extremely high dimensional accuracy and reliable sealing performance.

2. High-Quality Material Selection: The valve body and internal components are made of high-quality 304 or 316L stainless steel, possessing strong corrosion resistance, stable mechanical properties, high structural strength, and an ultra-long service life.

3. ISO 5211 High Platform Design: The standardized high platform structure allows for direct actuator installation without additional adapters, perfectly adapting to automated piping systems.

Sealing Performance and Operating Characteristics

The 3PC Threaded Ball Valve ISO5211 employs a float-type bidirectional sealing structure, paired with high-performance sealing seats such as PTFE, reinforced PTFE, or PPL. The meticulously crafted sealing surface ensures zero leakage, easy operation, and excellent wear resistance, enabling stable operation in high and low temperature environments.

Suitable for various working conditions including water, steam, oil, gas, and clean media. The three-piece split design allows for in-line seal replacement, greatly extending valve lifespan and maintenance efficiency.

Quality Control and Supply Strength

1. Rigorous Factory Testing: Every valve undergoes rigorous water pressure and air tightness testing before leaving the factory to verify shell strength and seal integrity, completely eliminating the risk of leakage.

2. Direct from Manufacturer: As a professional ball valve manufacturer, not a trading company, DIYE VALVE provides large-scale mass production services and direct factory supply, eliminating intermediaries and providing customers with highly competitive prices.

3. Comprehensive After-Sales Support: 3PC Threaded Ball Valve ISO5211 provides a full-cycle warranty, coupled with efficient after-sales service, rapid response, and timely problem resolution, ensuring long-term stable cooperation.

FAQs

Q: What is the function of the high platform on the 3-piece threaded ball valve?

A: The 3-piece threaded ball valve is equipped with a standard ISO 5211 high platform, which requires no additional mounting bracket. It allows direct installation of pneumatic and electric actuators, featuring simple assembly and high stability.

Q: What are the sealing materials and temperature resistance of the 3-piece threaded ball valve?

A: The standard sealing material is PTFE, with a temperature resistance range of -20℃ to 180℃. For high-temperature working conditions, PPL sealing is available, which can withstand temperatures up to approximately 300℃, ensuring reliable sealing and zero leakage.

Q: What thread standards are available for the 3-piece threaded ball valve?

A: We can provide standard threads such as NPT, BSP, G, BSPT, etc., to meet the diverse demands of domestic and overseas customers.
