Medium-temperature steam solenoid valve, steam solenoid valve

Medium-temperature steam solenoid valve structural features

1. Heat resistance: The electromagnetic part and the sealing part are made of special high-temperature resistant electrical materials and sealing materials, and various heat insulation measures have been applied.

2. Wear resistance: Reasonable material selection, and the valve cup and guide sleeve ingeniously utilize the lubricating effect of the fluid to reduce wear.

3. Cold condensation resistance: The condensate water from the steam pipeline is an important factor affecting the operation of the steam solenoid valve. This valve is not affected by the condensate water. 

 Medium Temperature Steam Solenoid Valve - Structural Principle

This valve is a pilot-operated, double-chambered electromagnetic valve composed of two main components: the auxiliary valve and the main valve. It controls the opening and closing of the main valve by the opening and closing of the auxiliary valve. Depending on the different switch states when the power is off, it can be classified as a normally-closed electromagnetic valve or a normally-open electromagnetic valve. The normally-closed electromagnetic valve, when in the fixed position, the auxiliary valve port is closed and the main valve is in an open circuit state. When the electrical signal enters the pilot valve coil, the moving core is attracted by the electromagnetic force and opens the auxiliary valve port. The pressure in the main valve cup disappears, and the medium pressure supports the main valve cup, opening the main valve and allowing the working medium to flow. However, when the electrical signal disappears, the moving core resets and closes the auxiliary valve port. Working medium enters the valve through the balance hole when the pressure tends to balance. Due to the main valve spring, valve cup weight and medium pressure, the valve cup moves downward, sealing the main valve port, and the valve is in a closed state. The normally-open electromagnetic valve, when in the fixed position, is acted upon by a spring, the auxiliary valve port is open, and the main valve is in flow. When the electrical signal enters the auxiliary valve coil, the moving core is attracted downward. When the pressure tends to balance, the main valve spring, valve cup weight and medium pressure cause the valve cup to move downward, sealing the valve port, and the valve is in a closed state. When the main valve is de-energized, the electromagnetic force disappears, the auxiliary valve opens, the pressure in the main valve cup rapidly disappears, and the medium pressure supports the main valve cup, opening the main valve port, allowing the medium to flow, and the valve is in an open state.

Medium-temperature steam solenoid valve is an actuator suitable for steam as the heating medium for automatic temperature control. It can perform two-position automatic control and remote control for steam heating equipment such as steam heaters, radiators, dryers, and various temperature control instruments, steam shaping machines, steam humidifiers, and steam boilers' steam pipelines. Medium-temperature steam solenoid valves are widely used in self-control systems of departments such as dyeing and chemical industry, textiles, printing and dyeing, food, medicine, cigarette manufacturing, cement products, petrochemicals, and metallurgy.
