PULSAR ZERO UNLOADER VALVE
Code: 1893
Product detailed description
The PULSAR ZERO UNLOADER VALVE – HIGH PRESSURE BYPASS VALVE 350 BAR is a cutting-edge pressure control component engineered for professional and semi-professional cleaning applications. Designed to handle working pressures up to 350 bar and flow rates of up to 40 liters per minute, this unloader valve delivers consistent performance in demanding environments such as industrial cleaning, agriculture, automotive wash systems, and municipal cleaning setups.
At the core of this unloader is a "zero pressure" bypass system, a unique feature that automatically releases residual pressure in the high-pressure line when the spray gun is closed. This intelligent discharge mechanism enhances operator safety, reduces wear on components, and provides a more comfortable handling experience, especially in high-frequency usage scenarios.
The PULSAR ZERO valve is particularly suited for use in compact high-pressure units, portable cleaning systems, and self-service car wash bays, making it an ideal choice for installations used by non-professional or occasional users. Its robust build and smart pressure-relief design ensure long-term durability and reliable system protection.
Compatible with a wide range of high-pressure pumps, hoses, and lance systems, this bypass valve integrates smoothly into cleaning equipment setups across industries such as the food sector, wine production, chemical industry, and municipal sewer maintenance.

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.
