The thread size of 2/2 way pilot steam solenoid valves range from 3/8" to 2". It can work under 180 ℃, mainly used for controlling the steams, that`s why called the steam solenoid valve. The working pressure for this solenoid valve is high, which can reach 1.5 MPa. The orifice sizes for this valve is also bigger than normal valve for same thread sizes to make the flow rate bigger. With its steady performance, this type of solenoid valve is widely used in the steam control systems in different countries.
