>Stainless Steel Nrv Valve is a non – return type valve that allows fluid flow in only one direction. Suraj Metal Corporationis a leading manufacturer and supplier of these in different Non Return Valve Material types. There are bronze and stainless steel materials used to make these valves. The SS Non Return Valve has different flow rates as 93, 2.34, 6.42 and so on.
They also have different working pressures but mostly 3000psi. The non – return valves have different thread types as well. The SS 304 Non Return Valve thread types range as BSPP, C.61 4-bolt flange and so on. The 304 stainless steel grade is used for general corrosive services with good corrosion resistance and strength. For more corrosive services, the SS316 Non Return Valve types are used as the 316 material has more corrosion resistance. The different types and sizes of the valves such as the 1/2 Stainless Steel Non Return Valve are chosen for different types of fluid flow systems. These valves have the advantage of controlling the flow of fluid in only one direction. The Wafer Type Non Return Valve is one of the most used in the industry and as a leading supplier we have other types as well. Please feel free to contact us for more information on these valves such as the Flanged and Screwed End Non Return Valves and others with the pricing.
