PA VS500 RELIEF VALVE
Code: 1937
Product detailed description
The VS500 RELIEF VALVE – 500 BAR HIGH PRESSURE SAFETY VALVE FOR SANDBLASTING & INDUSTRIAL CLEANING is a powerful safety component engineered for extreme pressure conditions in professional and industrial environments. Designed to operate at up to 500 bar and support flow rates of 80 liters per minute, this valve delivers exceptional overpressure protection in heavy-duty cleaning applications.
Built for use with high-performance plunger pumps and industrial washing systems, the VS500 is ideal for processes that demand precise pressure control under high load, such as water sandblasting, coating removal, rust stripping, and surface preparation in steel mills, shipyards, and construction environments.
This relief valve ensures the protection of high-value system components, including pumps, hoses, nozzles, and spray guns, by rapidly relieving pressure spikes that could lead to equipment failure. Its rugged construction and dependable response time make it well-suited for continuous use in abrasive and high-pressure cleaning tasks.
The VS500 integrates easily into stationary installations or mobile high-pressure units, commonly used in sectors such as mining, industrial maintenance, metalworking, and heavy vehicle restoration. With its capability to manage both high pressure and flow, this valve helps ensure system safety, operator protection, and operational efficiency.
