Product Features
The valve body is made of ductile iron material and has a white appearance throughout, which makes the product highly recognizable in industrial pipelines and can be quickly distinguished during installation. The impact resistance of the valve body itself is stronger than that of ordinary cast iron, and the damage rate during transportation is relatively low, reducing product loss. Even long-term use can maintain a clean appearance.
Product advantages
This fully lined PTFE pneumatic flange butterfly valve follows the ISO9001 quality management system. From the procurement of raw materials to every production process and pressure testing before the valve leaves the factory, there are dedicated personnel to strictly control and ensure that every batch of products has the same quality level.
If your purchase quantity is relatively large, we will adjust the production cycle according to the order quantity. In terms of after-sales service, a professional technical team can solve the problems you feedback within 24 hours. If any parts are damaged, we also support quick replacement to reduce your losses. In addition, valves can be widely used in industries such as chemical engineering and water treatment. For end customers, there is no need to select different media separately, which can better simplify the procurement process.
