Core Construction & Functional Features
Advanced In-Wall Integration
Built for secure integration into concrete or drywall partitions.
Maintains a precise depth allowance to match standard tile and plaster thickness, ensuring the operational head fits flush against the finished wall surface.
Dedicated PP-R System Compatibility
Directly connects via socket fusion to PP-R pipes, creating a homogeneous, leak-proof polymer bond.
Fully compliant with ISO 15874 standards for hot and cold water distribution systems in residential complexes, hospitals, hotels, and industrial facilities.
Forged Body & Protected Core
Forged Body: Hot-forged PP-R reinforced structure withstands heavy installation torque and shifting loads.
Protected Core: High-strength, electroplated iron core provides rigidity and remains isolated from the fluid pathway, reducing contamination and seizure risks.
Secure Female Connection Interface
Precision-machined internal threads ensure tight engagement with threaded adapters.
Facilitates secure mechanical-to-thermal transitions in restricted cavity spaces without compromising joint integrity.

Manufacturing Process & Quality Verification
Virgin Material Standards: Utilizes certified virgin PPR-C polymers tested for melt flow index, tensile strength, and thermal stability before production.
Rigorous Factory Testing: Every single valve undergoes 100% hydrostatic pressure testing at 1.5 times its rated working pressure (PN37.5) alongside strict GO/NO-GO thread gauge inspections.
Full Batch Traceability: Laser-etched production codes on every valve body record the exact manufacturing date, machine operator, and raw material lot number for complete supply chain transparency.
Frequently Asked Questions
Q: Will the iron core inside the valve cause rust or water contamination?
A: No. The treated iron core provides high structural rigidity and torque resistance, but it is completely isolated from the water pathway-preventing rust, water discoloration, or seizure.
Q: Do you support OEM/ODM customization with our brand logo?
A: Yes, we offer full OEM/ODM services. We can laser-etch your brand logo, model number, and batch codes directly onto the valve body, as well as customize packaging boxes to your exact specifications.
Q: What is the recommended wall installation depth for this concealed valve?
A: The valve body is designed with a standard installation depth tolerance of 40 mm to 65 mm from the outer pipe center to the finished wall surface, accommodating typical tile and plaster thickness while keeping the square head accessible.
Q: How does thermal fusion welding prevent leaks compared to mechanical joints?
A: Thermal fusion melts the external pipe and internal socket simultaneously, fusing them into a single homogeneous plastic structure rather than relying on rubber gaskets or compression rings, minimizing long-term joint loosening inside walls.
Q: What is the minimum order quantity (MOQ) for custom OEM brand laser-etching?
A: Generally 500 pcs per size for laser-etched logos and customized packaging, with flexible trial order options available for new B2B partners.
Q: Are these concealed valves compatible with both PPR type 3 and standard thermal fusion welding machines?
A: Yes, the socket dimensions comply with standard metric calibration, ensuring full compatibility with any standard commercial PPR socket fusion tool at 260°C.
Q: Do you have international quality management and product safety certifications?
A: Yes. Our manufacturing facility operates under strict ISO 9001 quality management standards, and our PPR concealed valves are CE certified, ensuring full compliance with European safety, health, and environmental protection requirements for building water systems.
