VB9 UNLOADER VALVE WITH MICROSWITCH
Code: 1807
Product detailed description
The VB9 HIGH-PRESSURE UNLOADER VALVE WITH MICROSWITCH – BRASS, 220 BAR, 30 L/MIN is a precision-engineered by-pass valve designed for use in professional high-pressure cleaning systems that require integrated control functionality. Built with a robust brass body, this valve is ideal for environments demanding durability, safety, and automation.
It operates efficiently with flow rates up to 30 litres per minute and pressures up to 220 bar, making it a reliable choice for plunger pumps in industrial cleaning systems, stationary car-wash bays, and automated high-pressure washers.
What sets this version apart is the integrated microswitch, mechanically triggered by the shaft movement. This feature allows seamless integration into systems that require electrical control signals, such as pump shutdown, safety interlocks, or status monitoring, significantly improving system automation and efficiency.
Additional features include:
-
Locknut adjustment for precise minimum and maximum pressure regulation
-
Reliable switching action for enhanced system control and safety
-
Suitable for municipal cleaning, agriculture and food industry, vehicle wash installations, and industrial machinery maintenance
This valve is especially useful where coordinated electrical-pneumatic or hydraulic systems are in place, making it a critical component in modern automated high-pressure cleaning setups. The VB9 with microswitch ensures consistent performance, safe operation, and effective integration into a wide range of industrial pressure cleaning environments.

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.
