The upper valve and lower valve can be fully opened and closed by Hand. Inside the valve body. There is a safety steel ball and safety valve seat. When the quartz glass rube is broken suddenly, the steel ball will remove to the safety valve seat in high speed pushed by high pressure steam to shut off the channel of the gauge automatically until the upper and lower valves is closed by hand. The ball will be reset by the pres-sure from the balancing tube and by its gravity. Therefore, false water level can be avoided. The gauge is provided with special safeguard, so it is safe and reliable, the gauge body itself is also a very good protection shade.
