SCI air valves are designed for various applications, including:
1. Portable Water
2. Flushing Water
3. Salt Water
4. Sewerage

The High Speed Double Orifice Air Valve is a versatile solution for air/vacuum and automatic air release applications. Its design ensures efficient fluid flow and prevents pipeline collapse under vacuum conditions.

Large Orifice:

  – Releases a significant amount of air when the fluid begins to fill the pipe, enhancing fluid flow efficiency.

  – Takes in air when the supply is cut off, preventing pipeline collapse.

Small Orifice

  – Releases small amounts of air to avoid bubble formation, which can hinder fluid transportation efficiency.

• Exhaust Air of Large Volume
  • As fluid fills the pipe, air is expelled through the large orifice, improving flow efficiency.
  • Once the pipe is full, a float ball rises, closing the vent to prevent leakage.
• Exhaust Tiny Air
  • Small amounts of air remain in the valve during fluid transport. When this air accumulates, the float ball drops, allowing the accumulated air to be released through the small orifice.
  • Once the air is released and the valve body is full of fluid, the float ball rises again, closing the small orifice.
• Absorb Air
  • If the pump stops, a vacuum may form in the pipeline. The plug opens rapidly, allowing air to be absorbed through the large orifice, preventing pipeline collapse.

To select the appropriate size of the High Speed Double Orifice Air Valve, the following guidelines can be used based on the diameter of the pipeline:

• – DN80: For pipelines below DN600
• – DN100: For pipelines between DN600 and DN900
• – DN150: For pipelines DN1000 and above

• Special Float Lever Design
  • The unique design of the float lever keeps the float positioned at the bottom of the valve. This ensures that the valve operates effectively, allowing for the release of trapped air while minimizing the risk of clogging.
• Preventing Waste Ingress
  • The structural design of the sewage air valve is specifically engineered to prevent waste from entering the vent channel. This is crucial for maintaining the integrity of the valve and ensuring that the plug and orifice do not become choked or blocked by debris.
• Efficient Operation
  • The sewage air valve allows for the automatic release of air during the filling of the pipeline and the absorption of air during drainage, which helps maintain optimal pressure levels within the system.

For a clear understanding of how the sewage air valve operates, please refer to the accompanying animation video. The video demonstrates the following key operational aspects:

• Air Release: As sewage fills the pipeline, the valve allows trapped air to escape, preventing air locks that could impede flow.
• Float Mechanism: The float rises and falls based on the fluid level, ensuring that the valve operates correctly without allowing waste to enter the vent channel.
• Vacuum Protection: When the flow decreases or stops, the valve can absorb air to prevent vacuum conditions that could lead to pipeline collapse.
