Check Valves

Our Tadpole range of patented check valves includes the smallest check valve in the world!


Our miniature check valves have a completely novel, patented design, which allows them to be extremely small and enables their manufacture in a range of resilient materials. With a cracking pressure of 50mbar - 2 bar, these new check valves are ideal for applications requiring miniaturisation or for use in instrumentation with space constraints.


Material options for the valve construction include Stainless Steel, Hastelloy C276 and Peek. Sealing materials include Viton and Kalrez. All options come at affordable prices, making it possible to regard them as laboratory consumables.


The valves have already been incorporated into a number of designs, but if we don't have what you want, please contact us to discuss customisation.
