WEIZIDOM’s Commitment to Global Industrial Solutions
As global industries shift toward local manufacturing and sustainable production, Turkey continues to position itself as a key industrial hub in the Middle East and Africa.
One of the most significant recent investments is the OYAK Carbon Black Project, a joint venture between Turkey’s OYAK Pension Fund and Taiwan-based International CSRC Investment Holding.
The new carbon black production facility, located in Ankara, represents a strategic step in meeting domestic demand while reducing import dependency. With an estimated market value of around $258 million, the Turkish carbon black industry is now one of the largest in the Middle East & Africa region.
In 2024, WEIZIDOM proudly joined this project as a trusted flow control solution provider, partnering with Alfer, a leading Turkish fan and air system manufacturer.
WEIZIDOM supplied high-performance ON-OFF Pneumatic Butterfly Valves valued at US$370,000, supporting critical systems in the carbon black production line — from air handling and process control to exhaust management.
About the OYAK Carbon Black Project
OYAK (Ordu Yardımlaşma Kurumu) is Turkey’s state-owned pension fund, known for its diversified portfolio across energy, cement, chemicals, and automotive industries.
Its collaboration with CSRC International (Taiwan) represents a powerful technological synergy — combining Turkey’s industrial expansion goals with Taiwan’s advanced carbon black production technology.
The project aims to produce premium carbon black, a key raw material used in:
* Tires and rubber products
* Plastics and coatings
* Industrial inks and pigments
* Energy storage (battery electrodes)
Once operational, the OYAK Carbon Black Plant will significantly reduce Turkey’s carbon black imports and strengthen the local supply chain, making it a critical project in Turkey’s industrial roadmap.
WEIZIDOM’s Role in the Project
Strategic Collaboration with Alfer
Alfer — one of Turkey’s most respected fan system manufacturers — was selected as a key equipment supplier for the OYAK project.
To meet the project’s strict reliability and automation standards, Alfer turned to WEIZIDOM, a trusted Chinese valve manufacturer with extensive experience in industrial valve design, manufacturing, and on-site engineering.

Product Highlights:
Tight shutoff performance even under high temperature and vibration conditions.
Corrosion-resistant materials (SS316) suitable for carbon-rich environments.
Automated control via pneumatic actuators for precise ON-OFF operation.
Compact design to fit within limited installation spaces in the fan and ducting systems.
Engineering Beyond Supply: WEIZIDOM’s On-Site Service
Unlike traditional valve suppliers, WEIZIDOM does more than manufacture.
For the OYAK project, our engineering team was directly dispatched to the construction site in Ankara, providing full technical support throughout the installation and commissioning phase.
Our On-Site Support Included:
Installation Guidance – Assisting local contractors with proper flange alignment, bolt torqueing, and actuator calibration.
Commissioning – Ensuring each pneumatic butterfly valve operated flawlessly under system load conditions.
Training – Conducting on-site workshops for Alfer’s engineering staff on valve operation, troubleshooting, and preventive maintenance.
After-Sales Follow-Up – Regular performance monitoring and feedback collection to ensure long-term reliability.
This hands-on approach is one of the key reasons international clients choose WEIZIDOM — we integrate engineering expertise with global logistics and after-sales service.
Why Pneumatic Butterfly Valves Are Essential for Carbon Black Production
The carbon black manufacturing process involves high-temperature combustion, gas circulation, and air management, requiring reliable flow control components to maintain operational safety and efficiency.
Process Air Control
Butterfly valves regulate airflow and pressure within combustion and cooling systems.
WEIZIDOM’s pneumatic actuators ensure precise ON/OFF control, crucial for maintaining consistent carbon black quality.
Exhaust Gas Handling
The exhaust system must handle particulate-laden gases at elevated temperatures.
Our WCB-body butterfly valves are designed for thermal expansion resistance and erosion protection, ensuring long service life.
Safety and Efficiency
In automated industrial plants, fast response time and tight sealing are critical for safety.
WEIZIDOM’s pneumatic butterfly valves are equipped with fail-safe actuators, allowing automatic shutoff in case of air supply failure.
