Look no further - probably the smallest spring assisted check valve in the world

Our Tadpole range of check valves and miniature check valves are engineered to the highest standards and offer end users unique solutions. Our check valves offer practical solutions for applications where space is at a premium and reliability is essential. As a company who design and manufacture precision equipment, we realised that a new design of check valve was needed to meet our requirements, so we created our own.

Our Tadpole check valves are so unique that we hold patents on them. The design lets us fit the spring assisted non-return system within surprisingly small devices, which allows us to manufacture the smallest spring assisted check valve in the world. We are also able to design specific check valves to accommodate your individual requirements in a small order batch, typically 100 units.
