PA VS450 RELIEF VALVE
Code: 1934
Product detailed description
The VS450 RELIEF VALVE – 300 BAR ULTRA HIGH FLOW PRESSURE SAFETY VALVE FOR INDUSTRIAL CLEANING & SURFACE PREPARATION is an exceptionally robust pressure relief valve engineered for intensive industrial environments where both very high pressure and flow rates are required. Capable of handling up to 450 liters per minute at pressures as high as 300 bar, this valve is ideal for use with large plunger pumps and high-volume water delivery systems.
Specifically designed to perform under extreme conditions, the VS450 is a preferred choice for operations such as steel mill descaling, industrial surface preparation, tank and vessel cleaning, and high-pressure washing in heavy manufacturing. It ensures system safety by rapidly discharging excess pressure, preventing potential damage to critical components such as pumps, hoses, and high-pressure nozzles.
Its performance capacity makes the VS450 suitable for use in steel processing, mining operations, aluminium production, and large-scale industrial maintenance—where operational uptime and equipment protection are vital. The valve’s durable construction allows it to withstand the rigors of continuous use in abrasive, high-pressure environments.
Whether used in stationary industrial cleaning systems or mobile high-capacity pump rigs, the VS450 relief valve ensures optimal protection and pressure control for the most demanding applications.

PA: valves and accessories for high-pressure cleaning
PA is an Italian manufacturer of components for pressure washers, vehicle washing and industrial cleaning equipment. Its portfolio covers pressure control, liquid delivery and operator accessories, helping equipment builders and service teams configure the complete cleaning circuit around the pump.
Product range and applications
PA products include unloader valves, spray guns, lances and other accessories used in high-pressure washing systems. The wider range also covers components for chemical application and specialised cleaning tasks. Applications extend from mobile pressure washers and car washes to cleaning installations in industrial environments.
Selection and system integration
Select each component according to the actual working pressure, water flow, temperature and connection type. An unloader valve must be compatible with the pump and circuit layout, while the gun, lance and nozzle need to work together at the intended operating point. Chemical compatibility and replacement-part identification are also essential for service work.
