Vitelli has successfully passed the type certification of low leakage valves

therefore, low leakage valves represent the development direction of valves in the future and will be more and more widely used. The products of Vitelli Valve Co., Ltd. fully meet the requirements of ISO standards and have successfully passed the type certification of low leakage valves, The company will certainly better provide high-quality environment for severe working conditions. From February, 2014 to July, 2015, the concept of low leakage stated that the valve has developed from meeting the limited internal and external leakage conditions based on the loss of comparative advantage to meeting the requirements for small discharge of the valve to the external environment; As for this requirement, the valve cannot be judged by conventional hydraulic and pneumatic tests. It is necessary to use more scientific means and precise instruments to detect small external leakage. This small leakage to the external environment is called low leakage

at present, with the continuous enhancement of people's awareness of safety and environmental protection, the increasing requirements for valves, the continuous strengthening of the domestic valve manufacturing industry's own technical strength, and the continuous improvement of domestic technicians' understanding of low leakage valves, the application scope of low leakage valves is constantly expanding. Especially in petrochemical, coal chemical, chemical and other enterprises, if the valves selected for flammable, explosive and toxic media can meet the low leakage standard, it will undoubtedly greatly reduce the leakage discharge of toxic, flammable and explosive media in the device, and avoid fire, explosion, about 32% of China's total blank poison and other accidents endangering the safety of life and property caused by valve leakage

therefore, low leakage valves represent the development direction of valves in the future and will be more and more widely used. The products of Vitelli Valve Co., Ltd. fully meet the requirements of ISO standards and have successfully passed the type certification of low leakage valves. The company is bound to provide high-quality and environment-friendly valves for severe and harsh working conditions through a high cycle fatigue test with a failure cycle greater than 5x104, Lay a solid foundation for Chinese made special valves to go global
