In recent years, Indonesia’s paper industry has experienced rapid expansion as part of the country’s industrial modernization and sustainability drive.
As factories upgrade to achieve higher efficiency, automation, and intelligent control, the need for high-quality industrial valves has become more critical than ever.
Among the key players supporting this transformation is WEIZIDOM, a global manufacturer specializing in valves and flow control systems.
In 2024, WEIZIDOM successfully supplied a complete valve solution for a leading Indonesian paper mill project, which involved the construction of a new production line equipped with automated, intelligent flow systems.
From project design to factory inspection, WEIZIDOM demonstrated its engineering strength, quality control, and customer-first philosophy.
The Indonesian client — a major producer in the pulp and paper industry — was expanding its new production line to meet rising domestic and export demand.
To achieve energy-efficient and smart process control, the customer chose WEIZIDOM as their valve and pipeline solution partner.
The project required both Carbon Steel (CS) and Stainless Steel (SS) materials, ensuring corrosion resistance and structural reliability for various fluid systems, including:
🔹 Pulp slurry transport
🔹 Water circulation
🔹 Steam and condensate lines
🔹 Chemical dosing and treatment
🔹 Compressed air and cooling water systems
| Product | Material | Actuation | Application |
| Butterfly Valves | Carbon Steel / Stainless Steel | Electric / Pneumatic | Process water, slurry, and air systems |
| Ball Valves (Control / Manual) | SS316 / CS | Electric / Manual | Chemical dosing, steam control |
| Knife Gate Valves (Control / Manual) | SS304 / SS316 | Pneumatic / Manual | Pulp slurry and wastewater |
| Globe Valves | SS / CS | Manual | Steam and condensate lines |
| Flanges & Gaskets | CS / SS316 | — | Piping connection and sealing systems |
Before shipment, the client’s engineering and procurement teams conducted a detailed on-site inspection at WEIZIDOM’s factory in China.
They inspected each valve’s dimension accuracy, surface finish, pressure test results, and actuator performance.
The inspection confirmed:
✅ Smooth and precise actuator operation
✅ No leakage during hydrostatic testing
✅ Perfect flange alignment and welding quality
✅ Professional packaging and clear labeling for export
After the inspection, the client expressed high satisfaction with WEIZIDOM’s production standards, professionalism, and transparency.
🔧 “The factory is clean, the products are well-organized, and every valve performs exactly as expected.”

WEIZIDOM has supplied valves to numerous pulp and paper projects worldwide, including Pakistan, Turkey, and Indonesia.
Our valves are designed to handle the unique challenges of paper mills — such as fiber-rich slurry, corrosive chemicals, and variable pressure systems.
Most valves in this project are equipped with electric or pneumatic actuators, enabling automated control within the client’s smart factory system.
This allows real-time monitoring, remote operation, and efficient energy use — essential for modern industrial plants.
Both Carbon Steel (CS) and Stainless Steel (SS316/SS304) are used to match the media type and working environment:
🔹 Stainless steel for chemical and corrosive fluids
🔹 Carbon steel for steam, condensate, and clean water lines
Each valve undergoes hydrostatic testing, torque verification, and material inspection in accordance with ISO, CE, and API standards.
WEIZIDOM ensures full traceability and provides material certificates (EN10204 3.1) for every order.
With over 1000 completed projects in 100+ countries, WEIZIDOM has become a trusted partner for EPC contractors, paper mills, water treatment plants, and power stations.
In modern paper production, automation is the backbone of consistency and productivity.
The use of electric and pneumatic actuators on WEIZIDOM valves helps optimize:
🔹 Real-time control of water and steam flow
🔹 Pressure balance in drying and pulping sections
🔹 Reduced manual operation and energy consumption
🔹 Increased operational safety and predictive maintenance
By integrating our valves into the client’s DCS (Distributed Control System), the plant achieved a higher automation level, aligning with Indonesia’s “Smart Factory” development goals.
The humid and chemically active environment of a paper mill poses a significant challenge for equipment longevity.
WEIZIDOM’s valve materials were carefully selected based on each section’s process conditions:
| System | Recommended Material | Valve Type |
| Chemical dosing | SS316 / PTFE sealing | Ball / Globe |
| Pulp slurry line | SS304 / Hard-faced seat | Knife Gate |
| Steam & condensate | CS / SS316 | Globe / Ball |
| Cooling & water recycling | Carbon Steel / EPDM | Butterfly |
| Wastewater | SS316 / EPDM | Knife Gate / Check |
This material diversification ensures maximum corrosion resistance, reduced downtime, and longer operational life.
After commissioning, the Indonesian client reported stable valve performance with no leakage or actuator malfunction during continuous operation.
👉 “WEIZIDOM’s valves helped us achieve precise control and reliable operation across our entire new production line.”
