Easy (simple disassembly type water supply quick air valve)

Easy (simple disassembly type water supply quick air valve)

A rapid air valve that complies with JWWA B 137 standards, can be disassembled with general tools, is easy to assemble, and has excellent maintainability.

With its unique structure, disassembly (from opening the pressure relief valve to removing the float valve guide) takes about 15 seconds! The compact design achieves lightweight construction, making it easy to handle! By attaching the Machino-style nozzle, it can be used for a wide range of applications such as pipe cleaning, temporary water supply, and water pressure measurement. Features: - The positioning pin prevents assembly mistakes of the arm piston and indicates the correct assembly position, allowing for safe disassembly and assembly. - The standard model can be used for a wide range of applications such as pipe cleaning, temporary water supply, and water pressure measurement by attaching the optional Machino-style nozzle. (The built-in nozzle type can be used similarly by removing internal components.) - The compact design achieves lightweight construction, making it easy to handle. - The anti-fall protrusion at the bottom of the valve box prevents internal components such as the float valve body and the movable valve body from falling into the main pipe. - Both the inner and outer surfaces are coated with epoxy resin powder to suppress rust formation. - The bolts are made of stainless steel (SUS304), ensuring reliability for long-term use. For more details, please contact us or download the catalog.

Airlight Rapid Air Valve (Stainless Steel) Machino Type Connection

Airlight Rapid Air Valve (Stainless Steel) Machino Type Connection

The connection part is a Machino-style female fitting 65A, made of stainless steel rapid air valve.

This is a stainless steel rapid air valve that can release the air trapped in the riser pipe of an underground fire hydrant. The connection part is a Machino-type female fitting of 65A, allowing for easy attachment and detachment to the nozzle section of the underground fire hydrant. Features: - Major components are made of stainless steel, providing excellent aesthetics and ensuring safe use over a long period. - The connection part is a plug-type intermediary fitting (Machino-type female 65A), enabling connection to the nozzle section of the underground fire hydrant (Machino-type male 65A). - It is ideal for short-term use to release air that tends to accumulate in the riser pipe of the fire hydrant during initial water flow, as residual air bubbles can easily collect there. - It is equipped with a pressure relief valve, allowing for the safe removal of the air valve by releasing residual pressure. - The exhaust performance meets the standard values of JWWA B 137 for rapid air valves used in water supply. - The floating valve body and the movable valve body are connected, applying the principle of leverage for smooth and reliable operation. For more details, please contact us or download the catalog.
