Product Overview
The Hot Sales Stainless Steel Air Release Valve is our best-selling universal automatic venting component optimized for full-scene commercial and industrial closed circulation piping systems. Differentiated from specialized single-scene liquid cooling or compact manifold air vents, this universal stainless steel air release valve balances heavy-duty industrial performance, wide media adaptability and cost-effectiveness, making it the preferred standard matching part for engineering integration, equipment OEM and municipal supporting projects.
Adopting integral one-piece stainless steel for the entire valve body and wetted parts, this air release valve abandons the easy-rusting and low-temperature-resistant defects of traditional cast iron and brass valves. Equipped with a high-sensitivity precision float and reinforced sealing assembly, it relies on pure mechanical buoyancy induction to achieve 24-hour fully automatic gas removal without electricity, manual operation or daily maintenance. It can effectively discharge free accumulated air, micro-bubbles and separated dissolved gas generated during pipeline water filling, pressure fluctuation, temperature cycle and long-term circulating operation.
Installed vertically at pipeline high points, terminal ends and equipment upper cavities, it fundamentally solves common system failures such as pipeline air lock, circulating flow attenuation, abnormal operating noise, water hammer impact and heat exchange efficiency decline. With excellent anti-corrosion, high-temperature resistance and pressure stability, it adapts to complex working conditions of multiple industries, covering HVAC heating and cooling, industrial process water, solar thermal energy, geothermal circulation and municipal pipeline systems, featuring wide applicability and ultra-low failure rate.

Installation & Operation Guidelines
•Vertical Installation Mandatory: The valve must be installed strictly vertically at the highest point of the closed pipeline and equipment upper cavity. Inclined or horizontal installation will cause air accumulation in the valve cavity and failure of automatic venting function.
•Pre-Installation Pipeline Flushing: Thoroughly clean and flush the entire circulating pipeline before installation to remove welding slag, rust debris and particulate impurities, preventing foreign matter from jamming the internal float assembly.
•Standard Thread Assembly: Adopt standard thread installation, control tightening torque moderately to avoid thread deformation and valve body cracking. Equip with high-quality sealing gaskets to ensure pipeline tightness.
•Working Condition Compliance: Operate within the rated PN16 pressure and -10℃~120℃ temperature range. Long-term over-pressure and over-temperature operation will accelerate sealing component aging and cause leakage failure.
•Regular Simple Inspection: For long-term operating industrial systems, regularly check whether the vent port is unobstructed and the valve body is leaking. Clean surface dust and impurities to ensure stable venting efficiency.
•Prohibited Working Media: Do not use in strong acid, strong alkali and high-concentration corrosive media to avoid structural corrosion and performance damage.
