We Release
the Unreleasable.
Cutlass Technologies is the UK’s leading specialist in on-site valve and penstock releasing. Since 2000, we have been releasing seized valves and penstocks in situ on live pipework, using our unique air-driven equipment to gradually free the valve at its seizure points.
To date, we have successfully freed over 27,000 valves, achieving a success rate of over 99.8%. Our expertise has earned the trust of over 200 clients, including some of the largest industrial and utility companies in the world, who consider us the best in the business for valve freeing, valve releasing, and penstock unseizing.

No Free - No Fee.
We are so confident in our valve and penstock releasing services that we operate on a “No Free – No Fee” basis. You only pay if the valve is successfully released. In the rare event we are unsuccessful, not a penny is charged—including mobilisation and demobilisation.
The quoted fee remains the same regardless of whether the job takes 7 hours or 7 days, giving you complete cost certainty.

Environmental Impact
Choosing Cutlass Technologies is also a sustainable choice. Releasing a seized valve avoids unnecessary replacements, reducing carbon emissions from manufacturing, transportation, and disposal.
By restoring your existing valves to full operation, our engineers save your company money, protect the environment, and make a meaningful contribution toward carbon neutrality.
