J011SA Stainless Steel Solenoid Valve product application

JO11SA stainless steel solenoid valve produced and sold by Baigang valve group is a common pipeline switching element in the automatic control system. It is widely used in the piping of petroleum, chemical, metallurgy, textile, food, shipbuilding, medical treatment, environmental protection and other industrial sectors to complete the gas , Steam, liquid, oil (viscosity ≤ 4 ° E) and other media of automatic control, energy saving and process control automation. 

J011SA Stainless Steel Solenoid Valve main technical parameters

Working principle of J011SA Stainless Steel Solenoid Valve

J011SA Stainless Steel Solenoid Valve is the direct use of electromagnetic force direct action valve. J011SA10 ~ 25 solenoid valve is the use of electromagnetic force and medium pressure differential pilot valve work.

Normally closed solenoid valve works, in the absence of electrical signals, the solenoid valve was closed. When the electromagnetic coil is energized to generate a magnetic field, under the action of electromagnetic force, the moving iron core and the fixed iron core are opened and the auxiliary valve port is opened (the direct-acting type directly opens the main valve port). At this time, the pressure in the upper iron core passes through Vice port unloading, due to the role of pressure difference, so that the main spool upward movement, to open the main valve port purposes, so that the medium circulation. When the magnetic field disappears after the solenoid valve is cut off, the movable iron core is reset under the action of the spring force to close the auxiliary valve port (the direct valve directly closes the main valve port). At this time, the medium enters the main valve cavity through the balance hole, So that the pressure on the cavity increases, the role of the pressure difference, the main spool reset the main valve port closed, the media cut off.

Normally open solenoid valve, in the power-off position, the role of the spring, vice port opened, the main valve circulation. When the electric signal enters the coil, the movable iron core is sucked by the action of electromagnetic force, the auxiliary valve port is closed, and the working medium enters the valve cup through the balance hole. When the pressure tends to balance, the main valve spring, the weight of the valve cup and the medium pressure The valve cup down, tightly seal the main valve port, the valve was closed. When the main valve is cut off, the electromagnetic force disappears and the auxiliary valve is opened. The pressure in the main valve cup disappears rapidly. The medium pressure holds the main valve cup and opens the main valve port. The medium is in circulation and the valve is open.

Note: Body material 2Cr13 and 1Cr18Ni9Ti, special materials, please indicate when ordering.

J011SA Stainless Steel Solenoid Valveshape and connection dimensions

Note: DN3 ~ 10 takeover size can be customized according to the caliber, body length of 46mm.

J011SA Stainless Steel Solenoid Valve installation precautions

1, the solenoid valve coil installation up, and maintain the vertical position, the solenoid valve arrow or mark should be consistent with the flow of the pipeline shall not be installed in a place splashing water or water leakage.

2, the solenoid valve working medium should be clean without particulate impurities, the valve should be installed before 80 ~ 100 mesh / hour filter, the main valve solenoid valve, moving iron core and fixed iron core surface dirt and filters, Must be regularly cleaned.

3, the use of long-term solenoid valve system, should be set by-pass device.
