Working Principle:
XD371XSignal ball valve with sound and light alarm deviceUsually installed at the inlet, outlet, or emptying pipe of pipelines or storage tanks, the valve is usually in a normally closed state. When the signal ball valve is opened, the travel switch is connected to the contact of the sound and light alarm device, emitting flashing lights and sound alarm signals to alert on-site personnel to pay attention. When the valve is closed, the power supply and the sound and light alarm device are disconnected, and the sound and light alarm disappears.
XD371XSignal ball valve with sound and light alarm deviceIt is a field instrument used in automatic control systems to detect the valve switch status. It is used to output the opening or closing position of the valve as a switch signal. It is applied in mechanical equipment accessories such as ammonia, oil, gas, liquefied gas, fire protection, water conservancy, storage tanks, etc. It is installed at pipeline outlets or exhaust pipes, and the valve switch action is confirmed by the action of the valve feedback device. It can also be used for interlocking protection and remote alarm indication in automatic control systems.
