WEIZIDOM Warmly Welcomes Iraqi Delegation to the Factory
WEIZIDOM Warmly Welcomes Iraqi Delegation to the Factory — Building a New Blueprint for Water Treatment Cooperation!
A Cross-Border Bond of Trust | A Visit to the WEIZIDOM Factory
This visit marked not only the quality acceptance of the first batch of water treatment equipment — valued at USD 300,000 and including butterfly valves, pressure reducing valves, foot valves, and check valves — but also a major milestone in deepening the strategic partnership between both sides.
Welcoming the Iraqi Delegation: Behind the USD 300,000 Order Lies Global Trust and Upgraded Cooperation
In May 2025, WEIZIDOM, a well-known Chinese industrial valve manufacturer, welcomed an important delegation from Iraq to its production base in Zhejiang, China. The core purpose of the visit was to inspect the first USD 300,000 order of butterfly valves, pressure reducing valves, foot valves, and check valves for water treatment, and to further discuss technical requirements for the next project phase, reinforcing a long-term strategic partnership.
Iraq, a country with urgent water management needs in the Middle East, represents a key market where WEIZIDOM’s technical strengths and product quality have gained recognition under extreme conditions such as high temperature and salinity.
From Factory Inspection to Customized Solutions: Deepening Technical Cooperation
During the three-day visit, the Iraqi delegation conducted a comprehensive review of WEIZIDOM's production lines and quality control processes, focusing on the following aspects:
Product Quality Verification
The delegation performed on-site pressure tests and sealing inspections on the butterfly and check valves from the first shipment. WEIZIDOM’s check valves demonstrated reliable opening and closing even under low differential pressure, suitable for Iraq’s unstable water pressure systems. The double-eccentric butterfly valve, featuring epoxy coating and alloy-welded valve seats, showed excellent corrosion resistance in wastewater applications — a major factor for continued procurement.
Technical Planning for New Projects
For the upcoming second-phase water treatment project, both sides discussed:
Use of wear-resistant PTFE-lined check valves to handle sand-laden water;
Compliance with AWWA C504 standards for butterfly valves to meet regional water supply regulations in the Middle East.
Why Global Clients Choose WEIZIDOM?
Full-Range Valve Solutions for Water Treatment
WEIZIDOM offers a comprehensive range of valves including gate valves, butterfly valves, ball valves, check valves, globe valves, water meters, and flow meters — forming a complete water control system.
In the field of check valves, we provide:
Swing check valves – low resistance, suitable for pump discharge;
Ball check valves – full bore, anti-clogging, ideal for wastewater;
Wafer check valves – compact design, space-saving installation.
This diverse product portfolio meets complex needs in a one-stop solution.
Rigorous Manufacturing Standards for Harsh Conditions
Certified under ISO 9001 and adhering to AWWA standards, WEIZIDOM ensures complete quality control from casting to assembly:
Material innovation: Ductile iron bodies with epoxy coating, resistant to 150°C and seawater corrosion;
Testing protocols: Each valve undergoes pressure, sealing, and cavitation simulation tests before leaving the factory;
Extended service life: Dry-shaft design isolates media from bearings to reduce wear and extend lifespan.
Global Project Experience
WEIZIDOM products are widely used in municipal water supply, sewage treatment, power plant cooling, and industrial pipeline systems. With over 200 successful cases across the Middle East, Southeast Asia, and Africa, the successful delivery of this Iraqi project further validates the reliability of WEIZIDOM products in desert environments.
Water Treatment Valve Technical Comparison: WEIZIDOM Advantages
Valve Type | Key Features | Water Treatment Benefits |
