Closure ties

Flange wedge valves

Flange wedge valves

Valves belong to closure rebar, which is installed in pipelines of various purposes and serve as a plug for different environments. To manufacture valves steel of different marks is used, including A352GrLCC (USA analogue), 2A(USA analogue), 420 (USA analogue). Depending on the characteristics, a valve can be used for plugging environments with various chemical composition:
— water and other liquids;
— gas and vapour;
— petroleum products.
According to the construction of the locking mechanism steel flange valves can be the ones with a retractable spindle and with non-retractable spindles.
