1/4-Inch Safety Valve, 8 Bar Pressure Relief

Brief Overview

This 1/4-inch male-threaded safety valve is engineered to protect pneumatic systems, compressors, inflators, and pressure tanks from exceeding safe operating pressures. The valve is factory-set to release air at 8 bar, preventing overpressure conditions that would damage equipment or create safety hazards. Built entirely from brass with precision machining, this valve delivers reliable performance in demanding industrial and workshop environments. For systems requiring higher pressure thresholds, higher-rated pressure relief valves are also available.

Key Features

• 1/4-inch male NPT thread connection – Direct integration into standard pneumatic system ports
• 8 bar pressure set point – Factory-calibrated for safe operation at this threshold
• Brass construction – Corrosion-resistant, durable in wet and dry compressed air environments
• Hexagonal wrench flats – Allows secure installation and removal using standard wrenches
• Knurled adjustment collar – Manual pressure setting adjustment when recalibration is necessary
• Internal bore design – Optimized air flow path ensures rapid pressure release when threshold is exceeded
• EN ISO certified – Stamped compliance markings confirm manufacturing and safety standards

Why Resellers Choose This Valve

Margin-Friendly Offering: Safety valves are essential stock items in any pneumatic supply operation. At 8 bar, this valve targets mid-range compressor systems—a high-volume market segment. Stock depth in 8, 10, and 12 bar variants ensures customer retention and repeat orders.

Low Return Rate: Once installed, safety valves remain in service for years with minimal maintenance. Defect rates are negligible, translating to solid margin protection and reduced warranty exposure.

Bundling Opportunity: Pair this valve with check valves for pneumatic circuits and coupling components to increase ticket size on system builds or repairs.

Installation & Maintenance Notes

Install the valve at the highest point of the pressure tank or system manifold to ensure proper venting of air when the pressure threshold is reached. Use thread sealant tape on the male threads to prevent leakage. The hexagonal nut behind the threads provides a wrench-hold point during installation. For recalibration or adjustment, turn the knurled collar carefully—clockwise increases the pressure setting, counterclockwise decreases it. Periodic inspection ensures the discharge port remains unobstructed.
