An explicit note about this domain
valvesmaker.com was previously used by a different company. From 2013 to 2019 it belonged to a hydraulic machinery manufacturer producing directional control spool valves and gear pumps for agricultural and construction machinery. That business is unrelated to DERVOS VALVE in every respect - different company, different products, different people.
We acquired the expired domain because the name describes what we do. We have not inherited, and will not imply, that company's history, certifications, customers, project record or founding date. If you find anything on this site suggesting otherwise, it is an error and we want to know about it.
This paragraph is here because an expired domain with a history is a genuine due-diligence question for a buyer, and it is better answered directly than discovered in an archive.
What we manufacture
High-temperature, high-pressure valves: gate, globe, check and stop-check, in pressure seal and integral forged construction, cast and forged, designed to ASME B16.34 and - for Chinese-standard projects - NB/T 47044. Materials from A105 through F22, F91, F92, WB36 and F347, selected against the duty rather than offered as a single grade.
Where we concentrate
One envelope, covered end to end: high temperature and high pressure. Selection review, design and manufacture of gate, globe, check and stop-check valves in pressure seal and integral forged construction, cast and forged, for steam, feedwater and severe process service.
That focus is deliberate. It is what allows us to answer a valve specification line by line, to state the rating basis for a grade at a design temperature rather than quote a single headline figure, and to put an inspector through a document package without improvising. For duties outside this envelope we would rather point you to the right supplier than take the order.
