Product Overview
The Flanged Single Orifice Automatic Air Vent Valve is a professional precision air venting component independently developed for closed-loop pressurized pipeline systems. Differentiated from multi-functional composite air valves with vacuum protection and large-flow exhaust functions, this single-orifice air vent valve focuses on refined and continuous air removal, specially designed to solve the hidden trouble of residual dissolved air and accumulated micro bubbles in long-term circulating pipelines.
Adopting integrated industrial flanged connection and high-sensitivity floating sealing mechanism, the valve realizes full-automatic unattended venting operation relying purely on water pressure and buoyancy changes without any external power source. During long-distance water transportation and closed-loop circulation operation, tiny air bubbles separated from the water medium will gather at the pipeline’s highest points. When air accumulates inside the valve cavity, the floating body automatically drops to open the vent channel and discharge air; after the air is completely exhausted, water fills the cavity to push the float upward for self-sealing, effectively preventing water leakage. Compact in structure and stable in performance, this single-orifice air vent valve is an essential precision accessory to optimize pipeline circulation efficiency, eliminate air resistance and reduce system operation failure rate.
Core Features & Advantages
•Precision Single-Orifice Targeted Venting — Adopts exclusive single-port refined venting structure, focusing on removing scattered micro bubbles and residual dissolved air that are difficult to eliminate by conventional valves. It achieves thorough air purification for closed circulating pipelines without causing pressure loss.
•Industrial Standard Flanged Connection — Equipped with integral PN10/PN16 standard flange, featuring large contact area, uniform stress and firm installation. It effectively resists pipeline vibration and pressure impact, solving the loosening and leakage problems of threaded air vents in long-term operation.
•Pure Mechanical Fully Automatic Operation — Built with high-precision floating sealing assembly, automatically sensing air and water level changes inside the pipeline. The whole venting and sealing process is completed intelligently, supporting continuous stable operation without manual supervision.
•No Leakage Sealing Performance — Optimized curved floating body and high-fit sealing surface achieve seamless closing after air venting. It maintains reliable tightness under rated working pressure, completely avoiding medium dripping and leakage.
•Anti-Scaling & Anti-Corrosion Valve Body — Made of high-quality industrial stainless steel, the integral casting body features smooth inner wall, excellent anti-scaling, rust-proof and oxidation resistance. It adapts to various complex water quality and outdoor harsh working environments.
•Professional Closed-Loop System Adaptation — Designed for closed heating, cooling and process water circulation systems. It continuously eliminates internal air accumulation, solves pipeline air lock, flow attenuation and operation noise problems, and improves system heat exchange and transmission efficiency.
•Simple Structure & Low Maintenance — Streamlined internal structure with fewer vulnerable parts and stable mechanical coordination. The detachable top cover design supports rapid on-site cleaning and component inspection, greatly reducing daily maintenance difficulty and cost.
•Ultra-Space-Saving Vertical Installation — Compact vertical layout with small floor area, perfectly suitable for narrow installation spaces such as pipeline high points, turning sections and terminal positions of various pipe networks.
