LD ball valves are a product of ChelyabinskSpetsGrazhdanStroy LLC, certified in accordance with Russian standards. This brand represents steel all-welded ball valves for industrial use, designed for installation in pipelines for the transportation of oil and gas, heat and water supply systems, and various units. The key to the quality of products of ChelyabinskSpetsGrazhdanStroy LLC is the constant control of material and workpieces at all stages of the manufacture of LD ball valves, as well as mandatory testing of each ball valve LD on test benches according to GOST R 54808-2011 "Pipeline valves. Valve tightness standards".
The all-welded body of the LD ball valve does not have any bolted sockets on the body, through which leakage is possible under dynamic loads of the pipeline. The ball valve uses not cast elements, as in most types of valves, but cold-formed blanks made from the pipe assortment of the largest domestic metallurgical plants. Used in the manufacture of parts cutting tool with mechanical fastening of plates of one of the leading manufacturers - "Iscar". Welding of workpieces is carried out automatically in a protective gas environment (80% Ar + 20% CO2), which is one of the leading technological processes compounds of various metals. The advantage of the welding process in gas mixtures based on argon is manifested in the high mechanical properties of the weld metal, as well as the value of penetration of the base metal. Welding uses G3Si1 welding wire (similar to domestic SV-08G2S) produced by ESAB Group. Welding manufactured by certified welders using specialized welding equipment from ESAB and Migatronic.
The range of LD ball valves includes nominal diameters, DN from 15 to 500 mm and nominal pressure PN up to 4.0 MPa. Depending on the method of connection to the pipeline, the following types of LD ball valves are distinguished:
- KSh.Ts.F. - ball valve with flange connection;
- KSh.Ts.P. - ball valve for welded connection;
- KSh.Ts.M. - ball valve with coupling (threaded) connection.
Ball valves LD can be installed on the pipeline in any position.
