Product Overview
This stainless steel top discharge automatic air vent valve adopts advanced disc type sealing structure, with gas discharged directly from the top of valve body. Different from traditional float core venting solutions, the disc sealing assembly realizes rapid opening closing response when gas accumulates, effectively coping with instantaneous gas surges in closed circulation pipelines.
The whole valve body is made of high quality stainless steel, resisting rust and medium erosion, avoiding metal ion precipitation risk when working with glycol mixed solution. Without power supply, the valve works fully automatically relying on medium buoyancy change. Installed vertically at pipeline high points, it continuously discharges free air generated during system filling, medium heating expansion and water supplement. It effectively solves air lock, pipeline noise, flow attenuation and heat exchange efficiency reduction caused by gas accumulation. Widely applied in solar thermal projects, building heating systems and general industrial closed circulation equipment.
Core Features & Product Strengths
•Direct Top Discharge Gas Channel Gas is expelled straight upward from valve top. Short gas flow path reduces gas retention inside cavity, greatly improves exhaust efficiency when large volume gas appears instantly.
•Precision Disc Sealing Internal Mechanism Disc shaped sealing pair replaces conventional float core structure. Quick opening closing response, strong anti interference ability against tiny scale particles, lower jamming risk in long term operation.
•Integral Stainless Steel Valve Body High strength stainless steel material, outstanding rust proof and anti corrosion performance. Compatible with heating water, solar heat transfer medium and low concentration glycol coolant.
•Power Free Fully Automatic Operation Driven purely by medium buoyancy variation. No electricity or manual intervention required, realize 24 hour unattended air exhausting after correct installation.
•Pressure Resistant Sealing Design Optimized disc sealing surface can adapt to cyclic pressure fluctuation inside closed pipelines. Stable sealing performance under normal working pressure, effectively prevent medium dripping.
•Compact Vertical Layout Main air exhaust direction is upward, occupies little horizontal installation space. Suitable for installation positions with limited lateral space on manifolds and pipeline high points.
•Standard Thread Connection Universal BSP / NPT male thread interface, convenient for on site threaded installation. Compatible with pipeline adapters, manifold outlets and solar loop connection ports.
•Wide Working Medium Compatibility Works well for neutral circulating water, solar heat transfer fluid and glycol based coolant. Suitable for both civil heating and general industrial circulation scenarios.

Typical Application Scenarios
Solar Thermal Closed Circulation Systems Installed at high points of solar collector loops. Quickly exhaust gas separated from heat transfer fluid under high temperature working conditions. Disc sealing structure reduces blockage risk caused by tiny scale inside solar circulation medium.
Commercial & Residential Closed Heating Circuits Mounted on heating manifolds and main pipeline peaks. Discharge large volume air generated during system water filling and temperature rise. Eliminate gurgling pipeline noise and guarantee stable heating output.
General Purpose Industrial Closed Loop Circulation Equipment Matched for industrial heat exchange units and circulating water systems. Handle periodic air accumulation caused by temperature fluctuation and medium replenishment, maintain stable equipment operation.
Medium Duty Glycol Mixed Fluid Circulation Loops Suitable for closed loops adopting glycol antifreeze solution. Stainless steel material improves corrosion resistance and extends whole service life of auxiliary pipeline components.
Building Auxiliary Heat Exchange Station Pipelines Used for auxiliary high point exhaust of building heat exchange stations. Compact vertical structure adapts to compact equipment layout requirements.
Customer Project Feedback
Solar Thermal System Contractor “We use this top discharge stainless steel air vent for multiple solar projects. The disc sealing structure is less likely to get stuck by scale. Top discharge design achieves fast gas removal under high temperature working conditions.”
Heating System Project Integrator “Many installation sites have narrow horizontal space. This vertical top discharge air vent solves our layout bottleneck. Stable sealing performance, few after sales leakage complaints.”
Circulation Equipment OEM Engineer “We value its stainless steel material and disc sealing mechanism. It performs reliably in glycol mixed medium loops, satisfying our standard for industrial supporting components.”
Why Choose ZTE VALVE stainless steel top discarge automatic air vent valve
This top discharge automatic air vent adopts unique disc sealing internal structure, different from traditional float core air vent products. The upward direct discharge gas channel delivers rapid exhaust response when facing sudden gas surges. Stainless steel valve body brings reliable anti rust and anti corrosion performance for heating, solar and industrial circulation systems.
Every finished valve passes tightness test and pressure cycle inspection before delivery. It is a trustworthy air exhaust component for solar contractors, heating engineering companies and circulation equipment OEMs.
Installation & Operation Precautions
•Install strictly vertically at pipeline highest points. Keep the top discharge opening completely unblocked. Horizontal or inclined installation will lead to exhaust failure and sealing leakage.
•Thoroughly flush the whole pipeline loop before installation, remove welding slag, metal debris and particulate impurities. Foreign particles may damage disc sealing assembly and cause failure.
•Do not apply excessive torque during thread assembly. Over tightening may damage stainless steel thread. Use qualified sealing gaskets for connection. Operate within rated PN10 pressure and 0 120 ℃ temperature range. Long term over pressure or over temperature will accelerate sealing component aging and trigger dripping. Do not arbitrarily disassemble internal disc sealing parts. Private disassembly will destroy original sealing matching relation and cause product failure. Not applicable for strong corrosive media or fluid containing large amounts of abrasive particles. Avoid heavy impact on valve body and top discharge port in installation and usage process.
