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.
