SIPHON BREAKER VALVES | HX-AP

Siphon breaker valves are installed at the top of pipe humps. They can break the vacuum and cut off the flow in no time when necessary or as soon as the system is out of order. Such valves safeguard the working units, keeping the flow from back running and prevent the pumps from back running which may easily cause the impellers to fly away.

The HX-AP VACUUM BREAKER 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.
