Industrial valves for Poland: district heating, water and UDT requirements
Poland has one of the largest district-heating systems in the European Union and a broad water and industrial sector that is being modernised with EU funds. Many networks were originally built with GOST-pattern valves. This guide explains what a Polish buyer needs from an overseas valve manufacturer.

Regulatory framework
Valves placed on the Polish market follow the Pressure Equipment Directive like elsewhere in the EU. In addition, the Office of Technical Inspection (UDT) supervises the operation of many pressure installations, and operators often ask for documentation that will satisfy UDT acceptance of the installation. Ask the end user early which documents UDT will need for the specific system.
District heating service
Hot-water district-heating networks run at temperatures up to about 130–150 °C and pressures commonly around PN16 to PN25. Steel gate valves and globe valves with metal seats are used for isolation in chambers and plant rooms, while welded-body ball valves are common in pre-insulated pipe systems. Specify the maximum temperature, the pressure class, the end connection (flanged or welding ends) and whether the valve is buried or installed in a chamber.
For replacements in older networks built with GOST valves, measure the face-to-face length and flange drilling on site. Supplying a valve with the original dimensions avoids pipe modifications during short summer shutdowns.
Documents and language
Polish utilities typically ask for EN 10204 3.1 certificates, test reports, declarations of conformity and instructions in Polish. Many engineers also read Russian, which can help with older drawings, but the formal documents should be in Polish or English as stated in the contract.
How TAZ supports Polish projects
TAZ manufactures steel gate valves, globe valves and check valves in GOST patterns as well as executions adapted to EN flanges. Send the network data and the dimensions of the valves to be replaced; TAZ confirms the matching execution, the test plan and the document package in the technical offer.
