Monel Spring Check Valve is used in industries such as fertilizer, pulp and paper, textile, heat exchangers, condensers, and petrochemical. Moreover, they are also used in pharmaceutical, and gas processing. These Monel inline Check Valves are passed through various tests before being supplied to the customers, these tests such as chemical, corrosion, pitting, and toughness ensure that the alloy has retained the best possible properties and is as per the international standards. These check valves are available in different category namely 400 and K 500.
Monel 400 Check Valve is said to resist seawater and caustic and salt solution. It can be hardened easily via cold working. It has good tensile strength and weldability. Due to their ability to resist corrosion in various conditions they can be used in non-oxidizing chlorine solutions and marine applications. Monel K500 Check Valve can resist chromium carbide precipitation. to improve the quality of the product chromium and titanium are added in trace amounts. They can work in temperatures up to 550 degrees C and offer resistance to a sour gas environment.
Check valves are ideally used to avoid the reverse flow of fluids however depending upon the end-use their material is selected. Monel Check Valve is one such material that is made up of nickel and copper. Along with iron and manganese in trace amounts. These elements provide the alloy its distinct characteristics. monel check valve manufacturers in India recommend the check valves produced in this material due to their quality to resist rust, general corrosion, and corrosion in strong materials. It can resist fine in 100% pure oxygen and can also resist acids.
