Sanking Premium PPH True Union Ball Valves (Double Union Hot-Melt Fusion)

Regulate and shut off chemical, industrial, and fluid-treatment pipelines smoothly with our premium Sanking PPH true union ball valves, available at Atradesen.com. Crafted from heavy-duty, chemical-grade PPH (Polypropylene Homopolymer), this professional-grade double union valve is engineered to withstand continuous operating pressures up to 1.0 MPa (145 PSI) and temperature loads ranging from -20°C to 100°C.

Featuring a high-contrast orange T-handle and double-union locking nuts, these inline valves are optimized for high-volume, low-resistance fluid delivery in acid pickling loops, electroplating lines, waste acid recovery, wastewater treatment, and chemical processing networks.

Advanced True Union Design for Easy Inline Maintenance

Standard inline ball valves require you to cut the pipeline if internal seals wear out, need cleaning, or become jammed by crystallization. Our Sanking Double Union (True Union) valve resolves this maintenance challenge: simply unscrew the two union nuts on either side of the valve body by hand. This allows you to slide out the central valve block for direct cleaning, ball inspection, or gasket replacement without having to cut, re-weld, or compromise the main piping line on either end.

Outstanding Chemical-Grade PPH Material Resilience

• Corrosion & Acid Resistant: Highly inert polymer structure designed to withstand severe pickling acids, waste acids, alkaline wash solutions, and industrial wastewater.
• Water-Grade Safe: Completely lead-free, non-toxic, and odorless, making these valves fully safe for household potable water setups, commercial aquaculture, and food processing lines.
• High Temperature Performance: Ideal for hot and cold water applications. Optimal pressure threshold is maintained between 5°C and 90°C (41°F to 194°F). Under-temperature or over-temperature beyond this range will gradually decrease pressure tolerance, with a maximum peak temperature threshold of 160°C (320°F).

⚠️ Sizing & Hot-Melt Fusion Guidelines

Nominal pipe dimensions are based on standard outer diameters. Please measure your pipe outer diameter (OD) before placing your order:

• Thread-Free Fusion Ends: Both union sockets are designed to connect to matching standard PPH pipes. The designated size (20mm to 110mm) corresponds to the outer diameter (OD) of your pipe.
• Weld Connection Methods: Requires standard hot-melt socket fusion or butt fusion welding using professional heating equipment to melt the joints together, securing a completely seamless, leak-proof molecular system.

Frequently Asked Questions (FAQ)

Q: What is the main operational benefit of a Double Union (True Union) Ball Valve?

A: In chemical piping networks, the ball valve may require cleaning due to crystallizing chemicals or debris. With a True Union design, you can simply unscrew the dual union nuts on both sides of the valve by hand. This lets you pull out the central valve body for cleaning or seal replacement without having to cut the welded pipes on either end.

Q: Is this PPH piping system compatible with strong acids and alkalis?

A: Yes. PPH Homopolymer offers superior crystalline density, making it exceptionally resistant to pickling acids, waste acids, alkaline wash solutions, and high-purity industrial effluents up to 100°C. It is widely preferred over PVC in tough industrial environments.
