T-T Flow are professionals in the design, manufacture and distribution of engineered waterworks valves and associated ancillary equipment to the water, process and allied industries.

Continued commitment to product development, quality and response to feedback has maintained our position at the forefront of the market.

Our flexible approach allows the supply of just a single valve, a combination of stock products or the ability to work with our clients to provide a complete engineered valve package, complete with ancillary equipment. We have extensive experience in the expert selection, mounting, configuration and functional verification of a wide range of actuators. All actuated valves are fully electrically and mechanically tested by our trained engineers prior to dispatch.

To complement our range of valves, a comprehensive selection of associated engineered equipment is available; with many items adapted to suit exact site requirements.

The majority of products in our range have WRAS (Water Regulations Advisory Scheme) approval. To achieve this accreditation, valves have undergone a stringent third party evaluation process encompassing mechanical assessments and material examinations to demonstrate that valves are not detrimental to water quality.

As part of T-T, alongside a large selection of valves, T-T Flow can also offer a vast range of pumps and bespoke electrical control equipment with aftercare provided by their service division.
