If you are seeking a factory that provides both wholesale solutions and fully customized services, you can confidently consider us. We have focused on Side Outlet Automatic Air Vent Valve manufacturing and global trade for years, building specialized expertise. Our commitment to quality is foundational: we apply strict, documented quality control procedures at every stage within our 15,000 ㎡ integrated industrial park. This includes rigorous inspection and testing of all incoming raw materials, precision manufacturing under controlled conditions, and final performance verification to ensure every valve delivers consistent, dependable operation and long-term durability for our partners worldwide.
The Side Outlet Automatic Air Vent Valve is a specialized device engineered to automatically purge accumulated air from pressurized heating, cooling, and plumbing systems. Its primary function is to maintain optimal system efficiency by continuously venting air pockets that can impede water flow, cause uneven heating or cooling, create disruptive noise, and accelerate internal corrosion. Featuring a side-outlet port, its design allows for convenient and flexible installation in confined spaces or where vertical mounting is impractical, directing the expelled air and any incidental moisture safely away from sensitive components. This design ensures reliable, maintenance-free protection for boilers, radiators, solar thermal systems, and other hydronic circuits.
Product Feature and Application
The side outlet automatic air vent valve is designed to efficiently release trapped air from piping systems while allowing flexible installation in limited spaces. Its side discharge outlet directs air away from sensitive components, reducing the risk of water splash. With a sensitive float mechanism and durable, corrosion-resistant body, it operates automatically without manual intervention. This valve is widely used in HVAC, heating and cooling water systems, and plumbing installations to prevent air locks, reduce noise, and improve system efficiency.

Installation guidelines
The side outlet automatic air vent valve should be installed in a vertical upright position to ensure correct float operation, even though the air discharge is through the side outlet. It must be positioned at the highest point of the pipeline or at locations where air is likely to accumulate, such as system risers or near pumps. Before installation, confirm that the thread size and connection type match the pipeline and apply suitable sealing material to prevent leakage. It is recommended to install an isolation or shut-off valve beneath the air vent to allow easy maintenance or replacement without draining the system. During system startup, keep the vent cap slightly loosened so trapped air can be released automatically. Ensure enough clearance around the side outlet for air discharge, inspection, and servicing, and avoid installing the valve in areas exposed to freezing temperatures or excessive vibration.
