Electromagnetic valve suitable for Cummins M11QSMISM engine

1, the adjustment accuracy is limited, and the applicable medium is limited.

Solenoid valves usually have only two states of switch, and the valve core can only be in two extreme positions, so the adjustment accuracy is limited.

2, action express, small power, light shape.

The response time of solenoid valve can be as short as several milliseconds, even the pilot solenoid valve can be controlled within tens of milliseconds. Because of its own loop, it is more sensitive than other automatic control valves. Properly designed solenoid valve coil has low power consumption and belongs to energy-saving products. It can also automatically maintain the valve position only by triggering the action, and it does not consume any electricity at ordinary times. The solenoid valve is small in size, which saves space and is light and beautiful.

Solenoid valves have high requirements on the cleanliness of the medium, and the medium containing particles is not applicable. If it is impurities, it must be filtered first. In addition, viscous media are not suitable, and the viscosity range of media suitable for specific products is relatively narrow.

3, various models, a wide range of uses

Although the solenoid valve has inherent shortcomings, its advantages are still outstanding, so it is designed into a variety of products to meet various needs and has a wide range of uses. The progress of solenoid valve technology is also centered on how to overcome the congenital deficiency and how to give full play to its inherent advantages.

Key points of construction and installation

1) The installation position and height of the valve must meet the design requirements of the mouth direction, and the connection should be firm and tight.

2) The valve must be visually inspected before installation, and the nameplate of the valve should comply with the current national standard GB12220 "General Valve Signs".
