M30C-40-AE44-SS32 40 AC: 220 0.63 1.36 38 0-1 5-150 185 460 Flange four holes. ø19ø4105
M30C-50-AE44-SS32 50 AC: 110 210 468 flange four holes. ø19ø4120
2. Use environment: the ambient temperature is not higher than 40 °C, and the relative temperature is not more than 85%.
3. Working medium: It should be clean and free of suspended matter.
4. Power supply change: Normal operation under the condition of rated voltage -15%-+10%.
Third, the working principle
M30C two-way high-temperature explosion-proof solenoid valve is a direct-acting, pilot-composite structure normally-closed two-way high-temperature explosion-proof solenoid valve operated by traction electromagnet. The illustration is off. At this time, it is closed by the pressure acting on the working medium in the upper chamber of the valve plug. When energized, the traction electromagnet will raise the guide. The opening of the discharge port is blocked by the valve stem, the pressure in the upper chamber of the valve plug rises, and the pressure difference between the upper and lower chambers causes the valve to close.
Fourth, installation and use
Before installation, purge the piping to prevent the welding slag and other objects from damaging the sealing surface.
When installing, pay attention to the arrow on the valve body, pointing to the direction of the medium flow.
It should be installed horizontally, allowing it to be inclined no more than 30° perpendicular to the horizontal line.
Use in accordance with technical specifications.
Do not paint on the other parts of the valve.
After installation, first turn on the power to observe the upper and lower movement of the guide rod, the upper valve is open, the downward is closed, after the action, the power can be cut off and the medium is introduced.
If the fluid is a liquid, loosen the venting needle after passing through the medium. Remove the gas from the valve and tighten to the original condition.
The connection and installation of the leads are strictly in accordance with the relevant regulations of explosion protection. The solenoid valve is grounded inside and outside, and installed at the same time, strictly omitted.
If the valve is slow to close, the needle cover can be unscrewed, the screw can be positioned, and the valve needle can be rotated counterclockwise to adjust the time required for closing.
If the valve is inflexible or cannot be fully opened, the fault is the same as above, and the valve needle is rotated clockwise, and the fault can be eliminated.

If the valve is not flowing enough, disassemble the valve body and the Y-type valve cover, loosen the nut on the valve stem, and adjust the distance between the valve plug and the valve body to meet the flow requirements.
