FAQs of PPR Stainless Steel Y Strainer Ball Valve

1. How to detect the PPR interface hot melt strength of the Y strainer ball valve?

Plumberstar manufactures tensile testing in accordance with GB/T 18742. After a hot-melt connection, the joint must meet the following tensile strength requirements: DN20 interface,≥3.8 kN; DN32 interface,≥5.5 kN; DN50 interface,≥8.5 kN. After testing, there must be no joint separation or cracking. Each production batch is randomly sampled and sent to SGS for third-party testing. Official test reports can be provided upon request.
In addition, Plumberstar’s factory laboratory is equipped with professional tensile testing machines, and customers are welcome to witness the testing process on site.

2. What is the PPR Y-type filter ball valve quality traceability system?

Plumberstar has built a full-process, traceable, and digital quality tracking system for its PPR stainless steel Y-type ball valves. Each product can be traced from raw material purchase to final delivery.

• Unique identification

Each production batch is given a unique 10-digit batch number.
This number is laser-engraved on the valve body (engraving depth: 0.1 mm) and cannot be removed.
The batch number is linked to the individual product serial number. It also contains key information such as production date, production line, and material code, so every batch can be checked online under a “one batch, one code” system.

• Full-process data binding

The batch number is connected to all key data throughout production, forming a complete traceability record: Raw material stage, Stainless steel heat number, PPR raw material brand (Yanshan Petrochemical PPR1120), Seal batch number, Material spectral test report, and food-contact safety test reports

• Production stage

Injection molding machine number, Molding parameters (temperature 260 ℃ ±10 ℃, holding time), Filter mesh inspection data, Ball core polishing roughness (Ra value)

• Testing stage

Hydrostatic pressure test curve (1.5× working pressure, 30 minutes), Salt spray test duration and corrosion data, Hot-melt joint tensile test report. Each test record is signed and confirmed by a quality inspector

• Logistics stage

Packing carton number, Logistics tracking number, Customs clearance documents, Shipping date, destination port, and customer information

• Easy traceability access

Customers can check traceability data in two simple ways:

• Website inquiry
  Log in to the official Plumberstar website and enter the valve batch number in the “Quality Traceability” section. All records for that batch can be viewed at once, including test reports, production data, and shipping details.
• Direct support
  Customers can also contact their assigned sales representative. After receiving the batch number, the representative will provide a complete traceability package within 2 hours, including PDF test reports and production photos.
• Fast issue tracking and response

If any quality issue is reported, the batch number allows fast problem identification: Abnormal test results can be traced to the exact test equipment and inspector, Material issues can be traced back to the raw material supplier, and the furnace number.

Plumberstar will issue a cause analysis report and solution within 24 hours. If a confirmed manufacturing defect is found, free replacement

3. What is the appearance quality standard of the PPR Y strainer ball valve?

Strictly implement the appearance standards of foreign trade exports:

• Valve body surface: no scratches, no sand holes, no burrs, uniform luster of stainless steel surface;
• PPR interface: consistent color, no bubbles, no dents, no impurities;
• handle: firm installation, flexible rotation, no looseness, no deformation;
• Logo: clear laser engraving, no ambiguity, no incorrect printing. Before packaging, use a PE bag to wrap it independently to prevent wear during transportation.

4. How is the PPR Y strainer ball valve’s resistance to high-temperature aging performance?

95℃ hot water accelerated aging test: put the valve into 95℃ hot water for 1000 hours, and after the test:

• PPR interface without deformation, no cracking, hot melt strength retention rate ≥90%;
• elastic retention rate of seals ≥85%, sealing performance without attenuation;
• Ball core flexible opening and closing, no stagnation phenomenon; test results show that the valve can meet the long-term use requirements of the hot water system.

5. Why choose Plumberstar’s PPR Y strainer ball valve?

Compared with other brands, Plumberstar stainless steel PPR Y strainer ball valves are suitable for residential use, industrial systems, and international trade projects. The main reasons are as follows.

Flexible customization for different customer needs
Many brands only offer standard models. Plumberstar is different.
It supports OEM and ODM customization, including valve size, pressure rating, and technical details based on customer requirements. Brand services are also available, such as laser engraving on the valve body and customized packaging.
The entry threshold is low. The minimum order quantity can start from 100 pieces, and Plumberstar can provide CAD and 3D drawings to support project design.
Strong capacity and fast delivery for large or urgent orders
Plumberstar operates a 25,000 m² production base with stable and mature production lines. Monthly shipments reach approximately 25 containers, enabling the company to handle large export and engineering orders.
Standard products are usually delivered within 30 days, much faster than the common 45–60 days in the industry. Customized products are also controlled within a reasonable lead time.
For urgent orders, priority production and flexible logistics options (sea or air shipping) can be arranged

6. What are the PPR Y strainer ball valve’s environmental and energy-saving advantages?

Plumberstar sticks to green production and energy-saving design. Its products come with clear advantages.
Eco-friendly raw materials. We use food-grade PPR and 304/316 stainless steel. They are fully recyclable and meet RoHS 2.0 and REACH standards.
Eco-friendly production processes. We run a closed-loop water circulation system. It boosts the water utilization rate up to 95%. Our injection workshops are fitted with waste gas treatment equipment. All emissions meet national standards.
Energy-saving in useWe optimize the flow channel design. The resistance coefficient is ≤1.2, cutting pressure drop loss by 25% compared with traditional split-type products. It reduces pump operation energy consumption. You can save a lot on electricity bills with long-term use.
Eco-friendly maintenance: The filter can be cleaned repeatedly. No need for replacements, which cuts down waste. Seals are made of degradable materials. They won’t pollute the environment when discarded.
Choose Plumberstar, and you choose green, energy-saving, and sustainable fluid control solutions.

7. How is the PPR Y strainer ball valve cost performance?

Purchase cost: It’s 15%–20% higher than the separate “ball valve + independent filter” combo. But it saves the extra cost of connecting pipes. The overall procurement cost is basically the same.
Installation cost: The all-in-one design cuts installation time by 50%. Labor costs go down by 40%.
Maintenance cost: The filter can be cleaned and reused repeatedly. No need for frequent replacements. Maintenance cost is only 30% of the separate type.
Equipment protection: It filters impurities effectively. This extends the service life of downstream equipment like pumps, water heaters, and water filters. It also saves money on equipment replacement indirectly.
Based on 10 years of household use, the annual overall cost of this product is 50% lower than the separate combo. It boasts a clear cost-performance advantage.

8. Can Plumberstar provide Certification requirements for the PPR Y strainer ball valve?

Certification scheme can be customized according to target market: EU: CE (PED), RoHS 2.0, REACH; USA: FDA, NSF; Russia: TR CU032; Middle East: SASO, GCC; Southeast Asia: SIRIM (Malaysia), PSB (Singapore); certification fee is negotiated according to order volume, large orders can be partially borne by the factory to reduce customer export costs.
