Características
PR (polypropylene random copolymer) shut-off valves are a type of PPR pipe fitting, primarily used for precise regulation, control, or shut-off of water or liquid flow within pipes. They are more commonly used in the maintenance, upkeep, or repair of residential or industrial equipment.
• Operating temperature ranges from 3 ℃ to 95 ℃, widely adaptable to both cold and hot water supply needs.
• Certification and compliance. Ctube PPR stop valve comply with NSF, WRAS, DVGW, DIN, TCVN and ISO requirements.
• Excellent hydrophobicity. Patented technology improves hydrophobicity efficiency by 10%-15%, making it the smart choice for builders and contractors.
• Non-toxic and Corrosion-Resistant. PPR material is non-toxic and additive-free, and is corrosion- and rust-resistant with a service life of over 50 years.

Preguntas frecuentes
PPR Stop Valve vs. PPR Ball Valve: Which one should I specify for main water distribution lines?
For main distribution lines requiring minimal pressure drop, a PPR Ball Valve (which offers full-bore flow) is the correct specification. PPR Stop Valves utilize a globe design that forces water into a Z-pattern. This makes stop valves ideal for throttling, regulating flow, or isolating specific fixtures, rather than serving as main system shut-offs.
What brand of raw materials do you use for manufacturing PPR stop valves?
Ctube strictly use 100% virgin Polypropylene Random Copolymer (PPR-C) sourced from top-tier global suppliers like Hyosung and Borealis. We guarantee zero use of recycled regrind. For the valve core and heavy-duty components, we utilize premium CW617N brass to ensure long-term durability, preventing the brittle failures commonly seen in lower-grade factory batches.
Can we customize the valve handle color and add our brand logo (OEM/ODM)?
Yes, we provide comprehensive OEM and ODM services for qualified B2B partners. We can customize the valve handle colors (e.g., green, orange or custom pantones) to match your regional market preferences. We also offer laser engraving or mold-embossing for your brand logo on the valve body, ensuring your brand stands out in local distribution channels.
¿Qué certificaciones internacionales poseen sus válvulas y sistemas de tuberías PPR?
Our manufacturing facilities operate under strict ISO 9001 quality management systems. Our PPR stop valves comply with DIN 8077/8078 y ISO 15874 international standards. We can provide full CE documentation and specific sanitary testing reports required for potable water applications in European, African, and Asian markets.
What is your Quality Control (QC) process to prevent leakage in bulk orders?
Every batch of our PPR stop valves undergoes rigorous multi-stage testing. This includes 100% pneumatic and hydrostatic pressure testing at PN25 before packaging. We also conduct accelerated thermal cycling tests and brass torque-resistance checks in our in-house laboratory to guarantee zero leaks and zero defect rates upon delivery.
What is the standard Minimum Order Quantity (MOQ) and production lead time?
For standard unbranded orders, our MOQ is highly flexible to support trial distributions. For customized OEM orders, the MOQ depends on the specific mold and packaging requirements. Our highly automated injection molding lines ensure a fast production lead time of 15 to 25 days for a standard 40HQ container, ensuring your supply chain remains uninterrupted.
How are the valves packaged for international freight and warehouse storage?
Our B2B packaging is designed for rough international handling. Stop valves are first sealed in protective inner polybags to prevent dust and oxidation, then packed into heavy-duty, reinforced 5-ply corrugated export cartons. All cartons can be printed with your custom SKUs, barcodes, and handling marks for seamless integration into your warehouse management system.
