The quick-closing valve-flap KZ 300, KZ 400 serves to prevent the reverse flow of steam into the turbine from the collector of the supplied heat network. The hydraulic drive is equipped with an accelerator for forced closing.

Check valves KO-100x21B, KO-150x21B in the flanged version of the lid, KO-100x21C, KO-150x21C in the flanged version of the lid with the body for welding and check valves KO-100x21, KO-150x21 in the flanged version of the lid and housing and valves KO-100x21F, KO-150x21F in the flanged version of the lid, with the welded housing is designed to prevent the reverse flow of the working medium in pipelines in the conditions of moderate and cold macroclimatic region GOST 16350-80.

Rotary check valves COP-50x10, COP-150x10, COP-200x4, COP-250x10, COP-250x4, COP-300x10, COP-300x4, COP-400x10, COP-400x4. The valve design allows, if necessary, to repair or replace the seat and the flap without dismantling the valve from the pipeline system. The ball element in the flap attachment unit ensures the best fit of the flap to the seat and increases the tightness of the valve gate. Designed for cases of emergency termination of the supply of the working medium, the valve prevents the occurrence of backflow of the working medium. It is used in pipelines of gas, oil and petroleum products, water in temperate and cold climates at ambient temperatures from plus 40 ° C to minus 60 ° C.
