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.
