MTM PV40/30 PNEUMATIC ON/OFF VALVE
Code: 1940

Product detailed description
The PV40/30 PNEUMATIC ON/OFF VALVE – 350 BAR AIR-ACTUATED WATER CONTROL VALVE FOR URBAN CLEANING & CAR WASH SYSTEMS is a high-performance control valve built for precise water flow regulation in medium to high-pressure cleaning systems. Operating at pressures up to 350 bar with a flow capacity of 30 liters per minute, this pneumatic valve is ideal for compact and automated cleaning environments.
Equipped with two ports (inlet and outlet) and two operating positions (open or closed), the PV40/30 functions through a compressed air circuit. When air pressure is removed, the valve automatically closes, securely stopping the water flow. This automatic shutoff feature ensures safety, system reliability, and efficient control, especially in self-service car washes, automated wash bays, and municipal cleaning vehicles.
Designed for integration with remote-operated or automatic cleaning systems, the PV40/30 is ideal where manual valve operation is impractical. Its robust pressure tolerance makes it suitable for more demanding installations than standard pneumatic valves, offering enhanced protection and flexibility in urban cleaning, vehicle sanitation, and light industrial wash applications.
This valve pairs seamlessly with high-pressure pumps, trigger systems, and hose kits, making it a reliable component in compact and automated industrial cleaning setups where control, safety, and high pressure must be balanced.

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.
