Material stainless steel 347 also known as UNS S34700 is the austenitic stainless steel that is columbium based with very good resistance to general corrosion and with very good resistance in a strongly oxidizing atmosphere. Also, this alloy is having good intergranular corrosion resistance into the temperature range of 427-816 deg C of chromium carbide precipitation. Also, it is having good resistance to the oxidation and creep strength at temperature 1500 deg F and is possessing low-temperature toughness. SS 347H or UNS S340 is the greater carbon version of SS 347. It is developed for enhancing the property of creep resistance. Also SS 347 Vane Valve is designed to make it useful at the high temperature applications in several industries. Stainless Steel 347 Instrumentation Valves have been made using crude materials along with modern machinery to ensure they meet the highest standards. The SS 347 Butterfly Valves are designed in various shapes, sizes and finishes. Stainless Steel 347 is a high carbon steel alloy that contains chromium and columbium.

Basically, valves are the mechanical tool that is used for the purpose of controlling the pressure and flow of the fluid into the process and system. Its main function is to control the pressure and flow. Various types of valves are available like a pressure relief valve, pinch valve, needle valve, butterfly valve, ball valve, plug valve, check valve, globe valve, and gate valve. These valves are also available in Stainless Steel 304L Instrumentation Valves and Stainless Steel 316Ti Instrumentation Valves.
