What is used
The main type is the pre-insulated fully welded ball valve for direct burial. Trunk lines and substations use steel gate valves, butterfly valves and check valves. Requirements for steel valve assemblies in pre-insulated systems are in EN 488.
What operators expect
Long service life, tightness, compatibility with leak surveillance systems, documentation and material traceability. Many operators buy from approved suppliers, so market entry usually goes through pre-insulated system manufacturers and distributors.
Where TAZ fits
TAZ can supply steel gate valves, butterfly valves and check valves for substations, boiler houses and trunk lines where pre-insulated assemblies are not required, as well as bare valves for insulation by the customer.
Requirements and logistics
CE under 2014/68/EU, EN standards and English documents. By sea through Turkish ports or by rail via the Middle Corridor and the Baltic. GSP+ applies to goods of Uzbek origin.
