View sizes and price list of Duplex Poppet Check Valve

Duplex Check Valve are widely known for their high strength and temperature properties. These valves comes in different connection methods such as threaded and socket weld. Excellent resistance to pitting, intergranular, and crevice corrosion makes Alloy 2205 Spring Check Valve a better choice for various industries including Petroleum industry. Critical pitting temperature of these valves is 35º C. They are also resistant to SSC corrosion at temperature upto 150ºC. Fit-Lok is trusted and reliable Duplex Check Valve manufacturer in India in size range of 1/2″ to 2″.

UNS S32205 Non Return Check Valves prevents the risk of backflow which makes it suitable choice in application where there is chance of contamination due to backflow of media. We are one of the biggest Duplex Poppet Check Valve supplier in India and can supply it in any small or large quantities. ASTM A276 Type 2205 One Way Check Valve are cost effective solution where 300 series material cant be used due to susceptible to SSC corrosion.

We keep ready stock of Alloy 2205 Inline Check Valves in range of 3000 PSI to 20000 PSI. We maintain the quality and performance of these valves by conducting various test on them at different levels of productions. Duplex 2205 Check Valve goes through tests like PMI, Ultrasonic, Magnetic particle testing which are done by our trained staff to achieve higher quality. We have supplied Duplex Stainless Steel Check Valve in Italy, Qatar, Brazil and Canada. These valves can be used in high pressure and high temperature applications such as power plants and boilers.
