The Robin Air Rob40330 Line Piercing Valve is a versatile and efficient solution for your air compressor line system. This valve, manufactured by Robin Air, is designed to provide easy line disconnection for maintenance and repair tasks, making it an essential addition to any workshop or industrial setup.
The Rob40330 is a line piercing valve, which means it can be installed directly into the air compressor discharge line without the need for drilling or tapping holes. This feature saves time and effort during installation and allows for multiple valves to be installed along the same line.
The valve body is constructed from durable brass material, ensuring long-lasting performance and resistance to wear and tear. The valve comes with a 3/8 inch NPT threaded inlet and a 1/2 inch NPT threaded outlet, making it compatible with standard air compressor hose connections.
The valve features a simple yet effective design, with a lever-operated handle that can be easily actuated to disconnect the air line. The handle is designed to be ergonomic and comfortable to use, even with gloves on. When the handle is in the down position, the valve is engaged, allowing air to flow through to the connected tool or equipment. When the handle is lifted, the valve disconnects from the line, making it easy to remove the tool or equipment for maintenance or replacement.
The Robin Air Rob40330 Line Piercing Valve is designed to operate at working pressures up to 150 psi (10.3 bar). It is suitable for use in a wide range of applications, including automotive, industrial, and construction industries. The valve comes with a one-year manufacturer's warranty, ensuring peace of mind for the user.
In summary, the Robin Air Rob40330 Line Piercing Valve is a reliable and practical solution for managing air compressor lines. Its easy installation, durable construction, and simple operation make it an indispensable tool for any workshop or industrial setup.
