Air valves with large opening

Air valves with a large opening are intake and exhaust valves that serve for the proper functioning of the pipeline. They are used to remove air from the pipeline before commissioning and to prevent the forming of underpressure when emptying the pipeline or a breakdown in the pipeline system. They are installed at the highest turning points of the pipeline and connect it to the outside atmosphere, acting completely automatically.

Butterfly valves with rubber coating

Butterfly valves with rubber coating are most often used as shut-off devices in pipelines for the transport of various fluids. As control devices, they are used when the fluid flow rate is relatively low. Compared to classic devices that have the same function, butterfly valves with a rubber coating have significant advantages. Simple and compact construction, significantly shorter installation length and lower shutter weight reduce the space required for installation, speed up and facilitate installation, handling and maintenance. The sealing rubber lining eliminates the possibility of contact of the working fluid with the shutter housing, allows the use of a standard housing for the flow of different fluids by changing the quality of the lining. They are used in plants for the transport of drinking, sea, technological, geothermal, waste and other waters, in the chemical and food industry, in the industry of alcoholic and non-alcoholic beverages, as well as for the transport of oil and oil derivatives, air and various acids and gases.

Non- slam check valves

Check valves are devices designed to prevent the return flow of the working fluid. They are installed in pipe systems to prevent leakage and loss of working fluid and to protect devices from damage that would produce backflow of fluid. These are self-acting devices, which perform their function automatically, without a drive system. They alowe the fluid to flow in one direction, otherwise their shut-off body automatically closes the bright opening of the pipe and thus prevents undesired backflow of fluid. Closing is done with the help of a spring and the pressure force of the return fluid. Check valves can be mounted in horizontal and vertical position, and since they allow the flow of working fluid only in one direction, it is necessary to pay attention during installation that the direction of the arrow on the valve housing corresponds to the direction of movement of working fluid in a given pipeline. They are used in plants for obtaining, preparing and distributing water, in communal facilities, in irrigation systems, in various plants of the chemical and petrochemical industry and in energy plants.
