የምርት አጠቃላይ እይታ

The PVC Double Union Ball Valve is a high-performance plastic flow control valve manufactured from premium PVC/CPVC/UPVC materials. Designed for durability and corrosion resistance, this valve series covers a complete size range from 1/2″ to 4″ (20mm to 110mm), accommodating diverse industrial and civil applications including water supply systems, chemical piping, water treatment facilities, environmental engineering, and pharmaceutical industries.

The ball valve operates by rotating a spherical valve core with a through-hole inside the valve body to achieve fluid on/off control and flow regulation. The True Union (double union) design allows the valve body to be quickly removed from the piping system without disassembling the pipeline connections, significantly facilitating equipment maintenance and replacement.

This product complies with multiple international mounting standards including NPT, BSPT, ANSI, ከ, CNS, JIS, and BS, making it suitable for installation requirements across different countries and regions. It holds ISO9001, ዓ.ም, ICAS, and NSF61 certifications, meeting EU standards and drinking water safety requirements.

ቁልፍ ባህሪያት

1. Premium PVC/CPVC/UPVC Material with Excellent Corrosion Resistance
The valve body is integrally molded from high-quality PVC, ሲፒቪሲ, or UPVC granules, ensuring uniform material distribution and structural stability. PVC material exhibits outstanding resistance to acids and alkalis, suitable for various chemical media environments. ሲፒቪሲ (ክሎሪን ፖሊቪኒል ክሎራይድ) offers enhanced temperature resistance and mechanical strength compared to UPVC. The valve body material is non-toxic and hygienic; CPVC material can also pass FDA certification, suitable for food and drinking water grade applications.

2. True Union Design for Easy Maintenance
The double union structure is a key feature of this product. This design allows the valve to be quickly disassembled without damaging pipeline connections, requiring no special tools. This significantly reduces maintenance difficulty and time costs in piping systems, particularly suitable for industrial applications requiring regular inspection or replacement.

3. Excellent Fluid Dynamic Performance
PVC piping has a smooth inner wall with a roughness coefficient of only 0.009, ensuring low flow resistance and high flow efficiency. This characteristic effectively improves the hydraulic conditions of the piping network and reduces pumping energy consumption.

4. Lightweight Design for Easy Installation
Plastic valves weigh only 1/6 of cast iron pipe equivalents. The lightweight body, combined with threaded connections (NPT/BSPT/ANSI, ወዘተ.), enables quick and simple installation while effectively reducing leakage risks.

5. Multiple Handle and Body Color Options
To meet different application scenarios and identification requirements, handles are available in grey, ቀይ, ሰማያዊ, and black; valve bodies are available in grey, ጥቁር, ነጭ, ቀይ, green, and blue, facilitating visual management and color-coded identification of piping systems.

የሚጠየቁ ጥያቄዎች

ጥ1: What is the maximum operating temperature for PVC and CPVC ball valves?

ሀ: PVC ball valves are recommended for temperatures up to 40°C (104°ኤፍ). CPVC ball valves can handle temperatures up to 54°C (129°ኤፍ) for continuous service, with intermittent service up to 70°C (158°ኤፍ) at reduced pressure. For applications exceeding these temperatures, alternative materials should be considered.

ጥ 2: What is the difference between True Union (Double Union) and standard ball valves?

ሀ: A True Union (double union) ball valve has detachable end connectors on both sides, allowing the valve body to be removed from the pipeline without disturbing the pipe connections. This design greatly simplifies maintenance, repair, and replacement. Standard ball valves are typically single-piece or split-body designs that require partial pipeline disassembly for removal.

ጥ3: Which thread standard should I choose — NPT or BSPT?

ሀ: This depends on your regional piping standards. ኤን.ፒ.ቲ (ብሔራዊ የቧንቧ መስመር) is the standard in North America, while BSPT (የብሪቲሽ መደበኛ የቧንቧ Taper) is widely used in Europe, እስያ, and Commonwealth countries. Both are tapered threads that provide a seal through thread interference. We also offer ANSI, ከ, CNS, JIS, and BS options to match your specific installation requirements.

ጥ 4: How does the pressure rating change with temperature?

ሀ: As operating temperature increases, the maximum allowable working pressure decreases. For PVC, derating begins above 20°C, with approximately 50% reduction at 40°C. CPVC maintains higher pressure ratings at elevated temperatures. Always refer to the pressure-temperature rating table and ensure your application operates within the specified limits.

ጥ 5: Can this valve be used for drinking water applications?

ሀ: አዎ. This valve is NSF61 certified, which verifies that all material components that come into contact with drinking water meet strict health effects standards. The certification ensures that no harmful chemicals leach into the water, making it suitable for potable water systems, food processing, and beverage production applications.
