Located in the cab of the locomotive, the emergency valve with electrical switch provides a direct means of venting brake pipe air pressure to effect an emergency train brake application. When this valve is actuated, the integral switch sends a signal to the locomotive computer, event recorder and/or electronic air brake communicator. The switch is wired with both a normally open and a normally closed contact.

3 Way Switching Valve The three way switching valve was driven by a stepper motor to switch the inside rotor to a specific port, but it is was triggered by DC7-33V voltage signals to power on and off just like common solenoid valves. Regarding this high pressure water solenoid ...
The switching valve is a type of multiposition valve without a public port but with dispensing ports around, a sample loop is required for such kind of valve to create a metering specific volume of fluids for a lab test, the applications are very flexible as you can name any ...
