2026-Zongda Automatic Control Valve (Wenzhou) Co., Ltd

Founded in 1987, our company is located at No.7 Meigong South Road, Guoxi Subdistrict, Ouhai District, Wenzhou City. Starting from scratch, our factory now covers an area of over 7,000 square meters. We are a professional manufacturer of PTFE lined valves integrating R&D, production and sales. With more than 30 years of development and innovation, we specialize in the research, production and sales of lined valves. After years of research and development, our straight-through PTFE lined diaphragm valve (diaphragm subjected to fatigue test) has obtained the Utility Model Patent (No.201320811672.1). We also supply domestically-made Saunders diaphragm valves imported from the UK for domestic manufacturers, providing high-quality anti-corrosion valves for key projects. Close to Wenzhou Railway Station and Panqiao Logistics Center, we enjoy highly convenient transportation, which strongly supports the development of our enterprise. Fluoroplastics feature outstanding resistance to strongly corrosive media. Lined on the inner wall of valve bodies, pipe fittings and outer surfaces of internal parts made of precision cast cast iron, ductile iron, cast steel and stainless steel, PTFE lining adapts to harsh working conditions with corrosive media and serves as an economical alternative to expensive rare metals. Its anti-corrosion service life is around 10 to 20 times longer than ordinary stainless steel valves. Widely recognized by customers, our valves are preferred equipment for installations in petroleum, chemical, pharmaceutical, chemical fertilizer and other industries. For years, we adhere to the guideline of “Market-oriented, Development driven by technology”. Through extensive market research and persistent efforts of our technical team, we have developed new products. Unique structural design, advanced new materials and optimized processes greatly improve all technical indicators, forming product series with proprietary technical advantages and good market reputation. Since establishment, we have focused on manufacturing PTFE lined valves and rubber lined valves. Our products comply with GB, BS, ANSI standards and customized non-standard specifications. The product range includes imported type diaphragm valves, ball valves, butterfly valves, check valves, globe valves, plug valves, discharge valves, gate valves, angle valves, straight-way valves, PTFE bellows compensators and other valves in various models and sizes. Partial products can be fitted with worm gear, pneumatic or electric actuators as required by customers. Over the past three decades, we have consistently followed the management principle: “Survive by quality, Develop by technology, Win market by reputation, Attract customers by reasonable price”. While continuously improving ourselves, we sincerely welcome new and existing partners at home to visit our factory and seek win-win cooperation.
