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.
Rotary gate shutters are meant for overlapping the environment’s flow in pipelines of various purpose. According to the customer’s requirements shutters can go with mechanical, pneumatic and electrical power trains. Depending on the exploitation conditions, main parts of the shutter (gate, body) can be made from various materials: carbon steel (2A, 1020, Gr.N2 and others– USA analogues), stainless steel, titan, bronze etc. Main technical characteristics: DN: , 65, 80, 100, 150, 200, 250, 300 mm, PN: Ру: 1,0; 1,6 MPa.
Ball plug valve from carbon stainless steel DN 10-1400 mm, PN up to 25,0 MPa; with clutch, flange joint and also with joint for welding; standard bore and full bore ball plug valves; ball plug valve with extended rod for underground works; crossover ball plug valves and many others.
At the customer's request ball plug valves can be produced with counterflanges, gaskets, bracing.
