Patent Vacuum Break Valve HX-AP

SME break valves are used as swift shut-off mechanism in siphonic pipelines and installed at top positions. They are very important part of the system in terms of safe use of stopping the water from pooling the diselectrified pumps which is likely to destroy the impellors.

SME vacuum break valve model HX-AP is a lift-and-break type of valve. The valve is mounted on top of a section of containers or pipes, functioning to break the spacial vacuum inside.

The valve opens by means of sucking the springed disc downwards when the pressure underneath drops to -0.01kg to -0.1kg. The atmosphere, thereupon, is able to break in and destroy the vacuum state. On the contrary, the valve shuts and is sealed when the pressure goes up to +0.05kg, pushing the disc upwards back to its place.
