Non-return threaded rotary valves pre DN are designed to automatically prevent backflow of the working medium in pipelines. They have a rotating element that opens or closes when the medium passes through, and provide a quick response to changes in pressure and flow direction.

Series: VC3232P-T.

Non-return threaded spring-loaded rotary valves pre DN are designed to prevent backflow of the medium. Such valves are usually mounted in conjunction with shut-off valves and are an integral part of pressure boosting systems for pumping a variety of media, industrial water treatment, pumping stations and other complex equipment.

Series: VCS3232P-T, VCSY3232P-T, VCSY3131P-T.

Non-return ball flange valves pre DN are designed to prevent backflow of the working medium in pipelines. They are used in sewage systems, storm drains, as well as in pipelines transporting process water, wastewater, and other liquids.

Series: VCB1414N-F.

Non-return spring flanged valves pre DN are designed to automatically prevent backflow of the working medium in pipelines. They protect the mains from oncoming traffic and prevent the occurrence of hydraulic shocks, increasing the safety of pipeline operation.

Series: VCS3232-Fb.

Non-return spring-loaded flange valves pre DN are designed to prevent the flow direction of the working medium in the pipeline from changing in the opposite direction. They are used in water supply systems, water distribution, pumping stations, industry and heat supply.

Series: VCS1313N-F.

Check valves o DN flanged flanged valves pre DN are designed to prevent the backflow of the working medium into the piping systems of heat and water supply, heating, and water treatment. They are used in areas where reverse flow of the medium is undesirable, for example, as protection for pumps and fans.

Series: VCL1-3232V-Fb, VCL1-3131V-Fb.

Non-return threaded ball valves pre DN are designed to automatically prevent backflow of the working medium in pipelines. They help to avoid improper movement of the coolant, including in multi-circuit heating systems, prevent improper operation of the pumps of the water supply system and prevent the reverse flow of wastewater in case of clogging of the sewer.

Series: VCB1433N-T.

Non-return lifting flange valves pre DN are designed to prevent backflow of the working medium in pipelines. They are used in cold and hot water supply, heating, steam and neutral media systems.

Series: VC1130M-F.

Non-return rotary flanged valves pre DN are designed to automatically prevent backflow of the working medium in pipelines. The working medium may include water, air, steam, ammonia, natural gas, petroleum, petroleum products, liquid and gaseous hydrocarbons, and media that are not aggressive to the materials of the valve parts.

Series: VC1111M-F, VCD1414E-F.
