The Vogiran single large orifice automatic air vent PN16 is manufactured with a ductile iron GGG40 body and rated for a nominal pressure of 16 bar. It features a single large orifice for venting air and trapped bubbles in pressurized pipelines, preventing air pockets and improving system efficiency. Internal components, including the float, disc, and automatic mechanism, are made of reinforced plastic or stainless steel for high corrosion and wear resistance, with an operating temperature range of 0°C to 120°C. Internal sealing uses EPDM or NBR washers to prevent fluid leakage. The valve design complies with DIN 3230 and EN 12266 standards and allows vertical installation on water, steam, and heating systems.
Depending on connection size G1/2–G1, the valve weight ranges from 0.5 to 1.8 kilograms. Internal and external surfaces are epoxy-coated or painted for corrosion protection. The single large orifice design ensures rapid and reliable air venting in pipelines, preventing trapped air. The Vogiran PN16 single large orifice automatic air vent delivers high efficiency, easy maintenance, and long service life, making it an essential component for water supply, heating, and industrial systems.

The large single-orifice PN16 WEG Iran air release valve must undergo hydrostatic pressure and leakage testing before installation in high-pressure pipelines. The test pressure is typically 1.5 times the nominal working pressure up to 24 bar for PN16 to verify body and flange connection strength. Internal seals and the float mechanism are tested under pressure to ensure leak-free operation. Periodic leakage testing after installation is also recommended to maintain safety and performance in water and steam pipelines. Correct pressure and leakage test results ensure valve longevity and prevent damage from water hammer and incomplete air release.
