Description
The NRV Series Non-return Valve is a compact pneumatic check valve designed to allow airflow in one direction while preventing reverse flow in compressed air systems. Constructed from durable aluminum alloy, the valve helps maintain system pressure, protect pneumatic components, and improve overall system efficiency by eliminating unwanted backflow.
Suitable for a wide range of industrial automation and pneumatic control applications, the NRV Series offers low cracking pressure, high flow capacity, and reliable operation across various pipeline sizes. Available in port sizes ranging from 1/8″ to 1″, these valves are ideal for air distribution systems, cylinder circuits, vacuum retention applications, and compressed air management systems.
The lightweight design, robust construction, and compatibility with PT, G, and NPT thread standards make the NRV Series an excellent solution for machine builders and pneumatic system integrators.
