PA VNR-I STAINLESS STEEL CHECK VALVE
Code: 1971/400
Product detailed description
The VNR-I STAINLESS STEEL CHECK VALVE – HIGH PRESSURE 400 BAR is a robust and reliable component designed for industrial high-pressure water systems. Constructed from corrosion-resistant AISI 303 stainless steel, this check valve offers exceptional durability and performance in demanding environments. With a pressure tolerance of up to 400 bar and a maximum flow rate of 180 liters per minute, the VNR-I is perfectly suited for a wide range of industrial applications.
Available in four different size variants, it supports flexible system configurations and enables effective control of water flow in complex cleaning setups. The VNR-I is commonly integrated into fixed high-pressure washing systems that supply water to one or multiple delivery lines, ensuring unidirectional flow and protecting equipment from backflow damage.
This check valve is a trusted solution in food processing plants, wineries, agricultural operations, municipal services, sewer cleaning systems, and industrial cleaning setups including automotive, mining, aluminium chemical processing, and firefighting sectors. Its high-pressure rating and stainless steel build make it particularly suitable for corrosive and heavy-duty environments.
Optimized for compatibility with industrial pumps, hose reels, valves, and cleaning nozzles, the VNR-I is an essential part of any high-performance cleaning or fluid handling system where reliability and resistance under pressure are non-negotiable.

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.
