 After 25 years, our R & D department developed the valve can be used in extreme environments, including the following: 
 - Teflon Valves 
 - High temperature metal seated valves 
 - Double eccentric metal seated valves 
 TEFLON VALVE 
 For services in which standard elastomers cannot be used, TTV offers this design aimed especially at the chemical, pharmaceutical, cosmetic and food industries. 
 They can be used for temperature -190 degrees Celsius and 850 degrees Celsius in the fluid between the estimated leakage at 1.5% to 2%. 
 The most common applications include: waste, industrial oven, exhaust systems, cogeneration, and so on. 
 LEAK-TIGHT METAL SEATED VALVE 
 Double eccentricity valve, with a metal ring that makes them lesk-tight at higher temperatures than when using an elastic ring. 
 Double eccentric valve metal installation 
 Double eccentric valve metal seal in high temperature environments than airtight rubber seal ring better. 
 Our facilities allow us to process all orders in record time, either for standard products or for special ones. 
 Every one of our valves undergoes a compre-hensive control of hydraulic tests in order to guarantee tightness. 
 We are equipped with the most fine tip of machinery and equipment, according to the requirements of different production standards and non-standard products. 
 All the factory shall be subject to strict inspection and hydraulic testing to ensure product quality.
