What is a Solenoid Valve and What is a Stop Solenoid Valve for the T190 Bobcat Engine?

This article focuses on solenoid valves and one of the categories, stop solenoid valves for the T190 Bobcat engine. It mainly introduces what is a stop solenoid valve and solenoid valve, the working principle, and so on. If you are interested, please read below, it is guaranteed to be a surprise.

What is Solenoid Valve Stop Solenoid Valve and for the T190 Bobcat engine

A solenoid valve for the T190 Bobcat engine is a piece of industrial equipment controlled by electromagnetic, which is used to adjust the direction, flow, speed, and other parameters of the medium in the industrial control system. The solenoid valve can be matched with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed.

The engine stop solenoid is an electromagnetic device that shuts off the fuel supply to the engine when the ignition is turned off.

Working Principle

The stop solenoid valve is not energized under normal conditions. At this point, most of the solenoid valves are closed and the fuel cannot pass through. The solenoid valve is energized prior to engine start, thereby opening fuel flow to the engine and starting the engine. When the engine needs to be stopped, the power to the stop solenoid valve is turned off, and the fuel line is also shut off. The engine also stopped working.

Stop Solenoid Valve Position

The stop solenoid valve for the T190 Bobcat engine is located in the fuel line before the fuel injection pump or at the inlet of the fuel injection pump.

Common Error

stop solenoid valves for the T190 Bobcat engine


The failure of the stop solenoid valve will directly affect the action of the switching valve and the regulating valve. The common faults are that the solenoid valve of the stop solenoid valve does not operate. The following aspects should be checked:

1. Stop the solenoid valve from loosening or falling off. The solenoid valve should not be energized, and the thread can be tightened.

2. If the coil of the stop solenoid valve is burned out, the wiring of the stop solenoid valve can be removed and measured with a multimeter. If the circuit is open, the coil of the stop solenoid valve will be burned out. The reason is that the coil is damp, causing poor insulation and magnetic leakage, resulting in excessive current in the coil and burning, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the number of coil turns is too small, and the suction force is not enough, which can also cause the coil to burn out. In emergency treatment, the manual button on the coil can be turned from the “0” position during normal operation to the “1” position to make the valve open.

3. Air leakage: Air leakage will cause insufficient air pressure, making it difficult to open and close the forced valve. The reason is that the sealing gasket is damaged or the slide valve is worn, causing several cavities to blow air. When dealing with the failure of the solenoid valve of the switching system, an appropriate time should be selected, and the solenoid valve should be processed when the power is lost. If the processing cannot be completed within a switching gap, the switching system can be suspended and dealt with calmly.

The introduction of this issue is here. If you want to know more about stop solenoid valves or solenoid valves, pay attention to LandTopMall. I believe there will be unexpected surprises for you.
