Safety valve Aerotec 4101064, 1/4-inch connection, pressure relief valve

Aerotec safety valve model 4101064 is a pressure relief valve with a 1/4-inch connection designed to protect compressed air and fluid systems from excessive pressure. Installed in pipelines or equipment, the valve opens at a pre-set threshold to release medium and reduce system pressure, preventing component damage and unsafe operating conditions. The compact construction and standard 1/4-inch threaded connection make it suitable for retrofit and new installations in workshop and light industrial environments.

Advantages

The valve provides reliable overpressure protection through a mechanical spring-loaded mechanism that operates without external power. Its metal body and precision seating ensure consistent operation and tight reseating after discharge. The 1/4-inch connection simplifies integration with common pneumatic fittings and lines. The device is designed for straightforward installation and low maintenance, offering long operational life when used within its specified pressure and temperature ranges.

Suitable for

• Compressed air systems in workshops and small industrial plants
• Pneumatic equipment and pressure vessels requiring safety relief
• Hydraulic or fluid lines within compatible pressure and medium limits
• Retrofitting or adding overpressure protection to compressors and air receivers

Key specifications

• Connection size: 1/4-inch threaded inlet/outlet
• Function: spring-loaded pressure relief
• Material: metal body and internal components suitable for pneumatic and compatible fluid use
• Installation type: inline or branch fitting in pipes or equipment ports
• Operating principle: mechanical opening at set pressure with automatic reseat after pressure drops

How to use

Select an appropriate mounting point in the pressure line or equipment port where the valve can vent safely. Install the valve using the 1/4-inch threaded connection, ensuring proper thread sealing and alignment. Set or verify the relieving pressure according to system requirements and manufacturer instructions before commissioning. After installation, gradually pressurize the system and check for leaks and correct operation by observing that the valve opens at the configured pressure and reseats when pressure returns to normal.

Usage recommendations

Regularly inspect the valve for corrosion, damage or buildup of debris and perform functional checks at planned intervals. Do not use the valve outside of the recommended pressure range or with aggressive media that may damage internal components. Replace the valve if it fails to reseat properly after discharge or if mechanical parts show wear. For safe venting, route discharge away from personnel and sensitive equipment.
