Mild Steel Ball Valves or carbon steel ball valves are less ductile but harder than the ordinary stainless steel valves. Suraj Metal Corporation is a leading manufacturer and supplier of the different types of valves such as the 1018 Mild Steel Gate Valve.
A gate valve uses a gate and a threaded stem that drives the gate in and out. The slow movement of the gate prevents the hammer effect on it while opening and closing. There are SS400 Mild Steel Butterfly Valve types that are used in similar systems. The valves can be of 2 way or 3 way input output systems. The connection ends can also be different with screws. The size of the valves varies as well. The 1020 Mild Steel Swing Check Valve is also used in flow control systems. The applications include water tanks, boilers, heat exchangers, water supply lines and other liquid transmission lines. As a leading supplier, we also supply the Aisi 1020 Mild Steel Needle Valve for precision applications. The needle valve is usually used in sensitive applications or in instrumental units. Please feel free to contact us for more information and pricing of the different MS Globe Valve types.
