Tianjin U-ideal Combination Air Valve for Wastewater
AV020 Combination Air Valve Description:
The AV020 Combination Air Valve integrates an air and vacuum orifice with an air release orifice in a single unit. It is specifically designed to operate with liquids containing solid particles, such as wastewater and effluents. This valve efficiently releases air (gases) during the system's filling or charging phase, allows air to enter the system when it’s being drained, and releases accumulated air from the system under pressure. The unique design ensures separation between the liquid and the sealing mechanism, guaranteeing optimal performance.
Key Features:
- Designed for use with liquids carrying solid particles like sewage and effluent
- Unique "air gap" design separates the liquid from the sealing mechanism
- Combines the functions of both an air/vacuum valve and an air release valve
- Triple function:
- Discharges large volumes of air during system filling
- Admits air during drainage and water column separation
- Releases trapped air in pressurized systems
AV983 Combination Air Valve Description:
The AV983 Air & Vacuum Valves are also engineered for operation with liquids containing solid particles, such as wastewater and effluents. These valves discharge air during the filling process and allow air to enter when the system is being emptied. Their unique construction ensures the liquid remains separated from the sealing mechanism, ensuring reliable performance.
Key Features:
- Specially designed for liquids with solid particles
- "Air gap" design keeps the liquid away from the sealing components
- Less sensitive to pressure differentials, allowing a large orifice over a wide pressure range (up to 360 psi)
- Dual function:
- Discharges large volumes of air during system filling
- Admits air during drainage and at water column separation
Applications:
Tianjin U-ideal float-type air vents are commonly used in hydronic heating systems, water service lines, storage tanks, centrifugal pumps, gas lines, solvent filters, and similar equipment. They operate automatically, offering a simple and durable design that minimizes maintenance needs.
Why Remove Air from a Water System?
Air trapped in hot or chilled water systems can cause noise, corrosion, and increased maintenance costs. It may lead to air locks, which prevent proper system filling or pump priming. Air can also affect the accuracy of flow meters and control valves. In extreme cases, it may even temporarily shut down the system. Additionally, air significantly reduces heat transfer efficiency—just a 1mm layer of air can act as a barrier equivalent to a copper wall 13 meters thick. Entrapped air is especially damaging in chilled water systems, which lack the natural deaerating ability of hot water.
