Product Overview
The Vacuum Breaking Valve (also known as Vacuum Breaker Valve) is a specialized pipeline safety protection device designed to solve negative pressure and vacuum hazards in closed piping systems. Different from conventional cut-off, regulating and filtering valves, this valve focuses on pressure balance protection. When the pipeline stops water supply or generates instantaneous negative pressure, the valve automatically opens to inhale air and quickly eliminate vacuum state, avoiding pipeline deformation, collapse and medium backflow caused by negative pressure.
When the pipeline is in normal positive-pressure operation, the vacuum breaking valve remains tightly closed without water leakage and does not affect the normal fluid transmission. Adopting high-precision internal floating ball or diaphragm self-control structure, the valve realizes fully automatic air intake and pressure balance without manual operation or external power source. Made of high-quality stainless steel and brass materials, it features corrosion resistance, stable induction sensitivity and long service life, becoming an essential safety accessory for municipal water supply, industrial circulating water and heating pipeline systems.
Core Features & Unique Advantages
•Automatic Negative Pressure Induction & Relief — Highly sensitive internal pressure sensing structure automatically detects pipeline vacuum and negative pressure. It instantly opens for air intake to balance pressure and completely eliminate pipeline negative pressure hazards.
•Effective Anti-Siphon Backflow Protection — Prevents siphon phenomenon caused by negative pressure in high-rise and long-distance pipelines, avoiding medium backflow, water pollution and secondary contamination of water supply systems.
•Pipeline Anti-Collapse Protection — Eliminates vacuum suction force inside the pipe during sudden water stop or pressure drop, effectively protecting plastic pipes, thin-wall metal pipes and large-diameter pipelines from deformation and collapse.
•No Leakage Positive Pressure Sealing — Under normal pipeline positive pressure, the valve maintains reliable closed sealing state with zero water spraying and zero leakage, ensuring no impact on daily pipeline operation.
•Pure Mechanical Automatic Operation — No electricity, no gas source and no manual intervention required. Relying entirely on pipeline pressure changes to complete opening and closing cycles, realizing unattended safety protection.
•High Sensitivity & Fast Response — Instant pressure relief response for instantaneous vacuum generated by pump shutdown, valve closing and pipeline water hammer, avoiding delayed protection and residual negative pressure damage.
•Anti-Corrosion & Hygienic Material Design — Premium stainless steel and copper alloy materials resist rust and scale, meeting drinking water sanitation standards. No secondary pollution, suitable for clean water supply systems.
•Simple Structure & Maintenance-Free — Integrated mechanical structure with fewer vulnerable parts, stable and durable performance. No regular disassembly cleaning and maintenance required, greatly reducing system operation costs.
•Wide Working Condition Adaptability — Adaptable to cold and hot water pipelines, suitable for municipal water supply, industrial circulation and heating systems, with stable performance in temperature and pressure fluctuation environments.
