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. This valve is specifically designed to handle liquids containing solid particles, such as wastewater and effluents. It efficiently releases air (gases) during system filling, allows air intake when the system is draining, and discharges accumulated air under pressure. The unique design separates the liquid from the sealing mechanism, ensuring optimal performance and durability.
This valve is ideal for systems that deal with sewage and industrial waste, offering reliable operation even in harsh environments.
Key Features:
- Designed for liquids with solid particles, such as wastewater and effluent.
- Unique "air gap" design prevents liquid contact with the sealing components.
- 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 Valve is also engineered for use with liquids containing solid particles, like wastewater and effluents. It discharges air during system filling and admits air when the system is being drained. Its innovative structure ensures liquid does not interfere with the sealing mechanism, providing stable and efficient operation.
Main Benefits:
- Specially made for wastewater and similar fluids.
- Unique "air gap" design keeps the sealing components free from liquid contact.
- Less sensitive to pressure changes, allowing a large orifice size for a wide pressure range (up to 360 psi).
- Dual functionality:
- Releases air during system filling.
- Admits air during drainage and at water column separation.
Applications:
These float-type air vents are commonly used in hydronic heating systems, water service lines, storage tanks, centrifugal pumps, gas lines, solvent filters, and other similar equipment. They operate automatically and are known for their reliability and minimal maintenance needs.
Why Remove Air from a Water System?
Air trapped in hot or chilled water systems can lead to various issues, including noise, corrosion, and higher maintenance costs. It can cause air locks, which hinder system filling and pump priming. Additionally, it may affect the accuracy of flow meters and regulating valves. In extreme cases, it could even temporarily shut down equipment.
Air and other non-condensable gases significantly reduce heat transfer efficiency. A thin layer of air can act as a major barrier, similar to a copper wall 13 meters thick. Entrapped air is particularly harmful in chilled water systems, which lack the natural deaeration ability of hot water.

Screw Conveyor
Screw conveyor is a kind of continuous conveying equipment without flexible traction mechanism. It mainly used to convey powder, granular and small lump material which is less viscous and hard blocking, such as coal, slag, cement, grain and etc. It can be widely used in building materials, chemicals, power, metallurgy, coal and other industries.
It's usually combined with Cement Silo to delievery powder and cement to the mixing plant, we specialized in Concrete Mixing Plant, as we all know, the Modular Skip Concrete Mixing Plant and Modular Conveyor Concrete Mixing Plant, and stationary mixing plant always used it to delivery powder,except that, we produce Hammer Head Tower Crane and Flat Top Tower Crane , we committed in provide better service with you!
Features:
Adopt one-time forming continuous blade, variable pitch type
Using cast aluminum alloy intermediate hanger connection, wear-resistant and long service life.
The domestic first universal feeding port is adopted, which is more conducive to installation and production.
It is assembled in multiple sections, which is convenient for flexible transformation.
