Need to ensure that liquids flow only in the desired direction? Choose this RS PRO non-return valve. The plate inside the valve is free to swing but pushes against a seal when liquid flows in the incorrect direction, causing the valve to seal.


It's clearly labelled with the flow direction on its side for ease of operation. The end connectors have a 2-inch threaded design, making the valve easy to install in the majority of compatible fluid systems.


The valve has a stainless steel construction to ensure durability and protection against damage in harsh conditions. You'll find this type of valve used to control the flow of water, or in hydraulic systems up to 14 bar.
