Product Overview
This high capacity stainless steel automatic air vent valve is engineered for closed circulation systems that produce large volume intermittent accumulated gas. Distinguished from compact small cavity air vents, it adopts an enlarged internal air collecting chamber, which can store substantial gas before triggering automatic exhaust, avoiding frequent cycling venting caused by small bubble bursts.
Fabricated from robust stainless steel, the valve resists oxidation and medium corrosion. A manual bleed screw is fitted on the top cover. Users can manually release residual trapped air during system commissioning, startup or maintenance without valve disassembly. Relying on mature float actuated mechanical principle, it runs fully automatically under normal operating conditions. Vertical installation at pipeline high points effectively evacuates massive air generated during system filling, water replenishment and thermal expansion. It eliminates air lock, pipeline knocking noise, flow shortage and heat output decline, widely applicable for heating networks, solar thermal projects and large size closed water circulation loops.
Core Features & Product Strengths
•Oversized Integrated Air Collecting Chamber — Large capacity internal cavity stores bulk accumulated gas. Avoids frequent on off exhaust actions triggered by tiny intermittent bubbles, improves service life of internal sealing pairs.
•Stainless Steel Monolithic Body — Whole valve body made of stainless steel, superior rust proof and anti corrosion performance. Suitable for systems with slightly aggressive working media, outperforms ordinary brass vents in anti oxidation capability.
•Top Mounted Manual Bleed Screw — Built in manual bleed screw for auxiliary exhausting. Convenient to discharge stubborn residual air during system filling, initial startup or routine maintenance, no need to remove the whole valve.
•Mature Float Driven Automatic Exhaust Mechanism — Pure mechanical float working principle, no power supply required. Achieves unattended 24 hour automatic air release once correctly installed.
•Enhanced Anti Water Hammer Sealing Performance — Optimized internal sealing structure, adapts to pressure fluctuation and water hammer impact frequently seen in heating and solar circulation pipelines, effectively prevents medium dripping.
•Standard External Thread Connection — Universal BSP / NPT male thread interface, simple threaded in mounting. Compatible with manifold outlets, pipeline high point adapters and solar loop terminals.
•Wide Operating Condition Adaptability — Tolerates wide temperature and pressure range, works steadily for long time continuous operation of heating, solar thermal and general industrial closed circulation pipelines.
•Low Maintenance Industrial Construction — Robust mechanical structure, less vulnerable to fine impurities in circulating water. Reduces on site maintenance workload for engineering projects.

Typical Application Scenarios
Designed for closed circulation systems featuring large volume intermittent gas generation:
Central & Floor Heating Closed Circulation Systems — Installed on heating manifold high points and main pipeline peaks. Handles large amount of air produced during system water filling and temperature rise, removes gurgling noise and guarantees uniform heating efficiency.
Large Scale Solar Thermal Circulation Loops — Deployed for solar collector arrays and heat exchange closed loops. Copes with gas separated from heat transfer fluid under high temperature solar working conditions. Manual bleed screw simplifies field commissioning work.
Building Closed Loop Water Supply & Heat Exchange Equipment — Matched for building heat exchange stations and circulating water units. Resolves periodic air accumulation caused by temperature variation and water replenishment.
Commercial Pool & Water Heating Circulation Systems — Applied for commercial water heating closed circulation pipelines. Stainless steel material enhances corrosion resistance for long term running.
General Industrial Closed Water Circulation Pipelines — Used for non critical industrial circulating water loops requiring large volume gas removal, suitable for engineering project batch procurement.
Customer Project Feedback
Heating System Engineering Contractor “We choose this large chamber stainless steel air vent for large floor heating projects. Its big air collecting cavity avoids frequent exhaust action. Manual bleed screw brings great convenience during system startup debugging.”
Solar Thermal Project Engineer “Working under long term high temperature solar circulation environment, stainless steel material effectively prevents rusting. It handles large gas volume generated by solar heating, and field failure rate stays low.”
Heat Exchange Station Equipment Integrator “Compared with small cavity compact vents, this model performs far better when large quantities of air are released. Stable sealing performance against pipeline water hammer impact, ideal for our heat exchange station supporting projects.”
Why Choose ZTE VALVE High Capacity Stainless Steel Automatic Air Vent Valve
This high capacity automatic air vent is developed specifically for closed circulation systems that generate large volume intermittent gas. The distinctive enlarged air collecting cavity reduces frequent actuation of internal sealing components, extending valve service life. Whole stainless steel body provides excellent anti rust and anti corrosion capacity. The top manual bleed screw meets practical commissioning and maintenance requirements on site.
Each product undergoes strict pressure tightness test before delivery. It is a reliable air exhaust solution for heating contractors, solar thermal integrators and heat exchange station equipment manufacturers.
Installation & Operation Precautions
Please follow the specifications below for better performance and longer service life:
•Must be installed vertically at pipeline highest points. Horizontal or inclined installation will disable large cavity gas collection function and cause vent failure.
•Thoroughly flush the whole pipeline loop before installation to clear welding slag and granular impurities. Foreign particles may jam the internal float assembly.
•Do not apply excessive torque during thread installation. Over tightening may damage stainless steel thread structure. Use qualified sealing gaskets for connection.
•Operate within rated PN10 pressure and 0℃-100℃ temperature range. Sustained over pressure or over temperature will accelerate sealing element aging and cause dripping leakage.
•The top manual bleed screw is only for temporary auxiliary exhausting during commissioning and maintenance. Do not keep it open in normal running status. Not suitable for strong corrosive, high particle content viscous medium. Avoid heavy mechanical impact on valve body during installation and usage.
