In the competitive world of industrial production, reliability and consistency define success.
Since 2019, WEIZIDOM has proudly partnered with Bulleh Shah Packaging (Pvt.) Limited (BSP) — a flagship company under the renowned Packages Group of Pakistan — to deliver high-quality valve and pipeline solutions for their large-scale paper mill operations.
Bulleh Shah Packaging (BSP) was established with a clear mission:
🤝 “To provide responsible and sustainable packaging solutions for brands in Pakistan.”
As the country’s largest renewable and liquid packaging board manufacturer, BSP stands at the forefront of corrugated packaging and environmentally responsible manufacturing. Its advanced paper mill in Kasur, Pakistan, serves some of the biggest names in the consumer goods and industrial sectors.
The story of WEIZIDOM and BSP is not just a supplier-customer relationship — it’s a seven-year partnership built on mutual growth, trust, and shared commitment to excellence.
Every long-term cooperation begins with a small step. In 2019, BSP first approached WEIZIDOM with a small test order for industrial valves and pipe fittings. At that time, BSP’s engineering team wanted to verify the quality consistency, material standards, and performance reliability of WEIZIDOM’s products in demanding paper mill environments.
Through repeated trials and performance evaluations, WEIZIDOM’s products proved their durability, precision, and corrosion resistance in high-moisture, high-pressure environments typical of paper production systems.
By 2025, the total contract volume between WEIZIDOM and BSP had exceeded USD 1.2 million, covering multiple phases of pipeline upgrades and expansion projects.
🤝 “We didn’t just sell products — we earned trust. Our consistency in quality and delivery timelines made WEIZIDOM a long-term strategic partner for BSP.”

Every valve and fitting from WEIZIDOM undergoes 100% inspection before shipment.
We use CNC machining centers, hydrostatic testing, and spectral material analysis to guarantee compliance with DIN, EN, and ISO standards.
Each component is tagged with material certificates (EN10204 3.1), ensuring full traceability from casting to final assembly — a critical factor for BSP’s quality assurance systems.
WEIZIDOM doesn’t provide one-size-fits-all solutions.
For BSP, we designed customized knife gate valves with optimized sealing rings and wear-resistant coatings to handle fiber-rich pulp flows.
Our engineering team also provided on-site installation guidance and technical drawings for better integration with BSP’s process pipelines.
In industrial projects, timing is everything.
WEIZIDOM’s flexible production capacity — supported by five major manufacturing bases across China (Wenzhou, Lianyungang, Shandong, Anhui, Tianjin) — ensures that urgent orders can be completed efficiently without compromising quality.
BSP continues to choose WEIZIDOM because we offer value beyond price — consistent performance, long service life, and technical reliability that reduces operational risks and long-term costs.
Butterfly valves, knife gate valves, and ball valves from WEIZIDOM are used across multiple systems in the BSP project:
| System | Application | Valve Type Used |
| Pulp & Fiber Flow Lines | Handles thick pulp slurry | Knife Gate Valve |
| Process Water Supply | Controls clean water to paper machines | Ball Valve / Gate Valve |
| Steam Condensate Lines | Manages steam and condensate flow | Globe Valve / Check Valve |
| Chemical Treatment Section | Resists acid and alkali corrosion | SS316L Ball Valve |
| Wastewater Treatment | Regulates sludge discharge | Knife Gate Valve / Check Valve |
🌿 Each component plays a critical role in ensuring efficient water usage, energy recovery, and environmental compliance — helping BSP achieve its goal of sustainable packaging production.
WEIZIDOM’s collaboration with BSP has gone beyond supply — it’s about technical partnership and sustainability alignment.
🌿 Sustainability: Our stainless steel valves and fittings contribute to BSP’s renewable packaging goals by minimizing leakage and improving energy efficiency.
