The VB80-303 UNLOADER VALVE 400 BAR – AISI 303 STAINLESS STEEL HIGH-PRESSURE BYPASS VALVE from PA is a high-performance unloader valve engineered for very high-pressure industrial cleaning systems. With a maximum pressure rating of 400 bar and a flow capacity of 80 litres per minute, it is built to handle intensive applications where extreme pressure and reliability are essential.
Crafted from AISI 303 stainless steel, the valve ensures exceptional resistance to high-pressure fatigue, corrosion, and mechanical stress, making it ideal for long-term operation in harsh industrial environments. Its robust construction supports use with high-pressure pumps in sandblasting units, paint and coating removal systems, and surface preparation equipment.
The valve’s black spring configuration, specifically tuned for 400 bar operation, ensures accurate and stable pressure relief via a bypass mechanism that protects both pumps and connected components from overload and pressure spikes.
The PA VB80-303 unloader valve is the ideal choice for professionals across industries such as metal treatment, mining, shipyard maintenance, and heavy equipment cleaning, where high-pressure performance and material durability are non-negotiable.
