2L series pilot-operated steam solenoid valve, it is 2/2way. It is high temperature can up to -5~185° C, so mostly for steam medium, we also call it steam valve. It is designed correspondingly to support higher pressure of 1.5MPa, the orifice also will be bigger than normal valve for same thread size to make larger flow rate. It can change the coils to be as explosion-proof solenoid valve
