Product Description
Check Valve, also known as a one-way valve or
Check Valves. Pipeline used to prevent reflux of a fluid valve. So pipeline fluid can only make one-way flow of fluid when the clock back, the flap valve can be shut down automatically to prevent backflow. According structure can be divided into two categories : elevating and spin-Kai (or a shake-flap). Former perpendicular to the valve flap valve passageway movements with Valve are generally designed as a cut-off valve and valve common. The latter is a flap valve around the sealing surface for rotating movement, resistance than elevating small, poor sealing performance.

JOC Machinery Co., Ltd. Was founded in year 2000, specializing in foreign trade of machinery parts and complete sets of equipment. The ranges of products and services covering construction and building machinery, petroleum machinery, mining equipment, power cable production lines, electric power fittings, vehicle and motorcycle parts, industrial vales and etc. Have been exported to more than forty countries and regions of the world.
To better serve customers, stable supply and the quality of the products, we have successively set up three production bases that all certificated with ISO9001 or TS16949: In 2001, the Jiangyin factory was founded, whose main operations are investment casting and CNC machining; In 2005, the Yangzhou factory was founded, whose main operations are steel forging, stamping, fabrication, gravity casting of aluminum and galvanizing finish; In 2011, the Nanjing factory was founded, whose main operations are lost foam iron casting. Furthermore, since 2005 our Jiangyin factory Uni-metals also has established a joint-venture foundry with a British company for automobile turbo charge wheel of vacuum casting, and soon afterwards established 2 branch plants in India and Mexico.
We are committed to team the talents, integrate industry resources, and strive to further develop into a great enterprise of machinery parts and equipment. We look forward to working with you to create a better future.
