This RS PRO non-return valve keeps liquids flowing only in a predetermined direction within your system. The valve is sealed by an interior plate that's free to swing but pushes against a seal when the liquid isn't flowing in the right direction.


The flow direction is clearly labelled on the side of the valve. It has 1-inch threaded end connectors for simple fitting on the majority of fluid systems of a compatible size.


The valve has a durable stainless steel body that can withstand harsh industrial conditions. Its design is suitable for hydraulic systems of up to 14 bar or for water flow control applications.
