Weidouli Valves Co., Ltd., founded in 1989, specializes in the production of high alloy valves. We cover an area of 43,500㎡ with a registered capital of 101.89 million yuan. Being committed to customizing for 30 years, we constantly develop new products that can better meet the working conditions by communicating with customers in different industries carefully. Our commonly used materials include Titanium, Zirconium, Nickel, Hastelloy, Monel, Inconel, Nickel Aluminum Bronze, Alloy 20, 904L, Duplex /Super duplex stainless steel, Tantalum, etc high alloy, and stainless steel.
Advanced manufacturing technology makes perfect quality. We concentrate on the development and production of special valves, owning class 100,000 clean room and over 100 support equipment including CNC processing equipment, vacuum welding equipment, heat treatment furnace, modifying equipment for vacuum surface, etc. Among them, modifying equipment for vacuum surface and vacuum protection welding equipment are developed by us in collaboration with Wuhan University, ZHEJIANG SCI-TECH UNIVERSITY and other universities. We make the best of new equipment and technologies to ensure the stability and reliability of our products.
In order to achieve zero defect and zero leakage, we have established information management mode and strict quality management system to ensure the traceability of each valve and component.
We are able to customize all kinds of valves according to your requirements with our advanced technical team of 60 people, including 25 senior and intermediate engineers. Meanwhile we introduce Solid Works mechanical design software from the United States to carry out professional three-dimensional design as well as accurate fluid and strength calculation.
To ensure the performance of the finished products being able to meet our customer’s requirements, we have established our valve technology laboratory which is equipped with alloy analyzer, direct-reading spectrometer, metalloscope, ultrasonic thickness gauge, helium mass spectrometric leak detector and other precision testing equipment, our valve flow testing bench to simulate working conditions and accurately control valve flow regulation and our physical and chemical analysis laboratory to accurately analyze the mechanical properties, structure and chemical composition of valve materials.
Over the years, we have been committed to providing customers with solutions to use valves under severe corrosion conditions, having won wide praise and trust from customers with our high quality service and reputation. We provide valves for chemical industry, military industry, ship, desalination, metallurgy, paper making, textile, electric power, natural gas and other fields, and our products are exported to more than 20 countries and regions such as countries in Europe, the United States, the Middle East, Japan, South Korea, etc.
