Sluice gates are used in melioration systems, in water discharge and water charge accumulation systems, in water treatment plants, hydroelectric power plants and other areas of economic activity. Sluice gates are not divided by nominal openings and nominal pressures, as they adapt to the installation place conditions, and their dimensions depend on the channel dimensions and the fluid height in front of the sluice.
Control valves are used in water treatment plants, hydroelectric power plants and other areas of economic activity. Control valves with a float are shut-off regulating valves which are primarily designed to regulate water level in the reservoir, i.e. to maintain water level at the required level.
Strainers are used in industrial pipelines in business facilities, power plants, heating plants and waterresource management facilities. Strainers are used to prevent the passage of smaller foreign bodies and various impurities through the pipeline. To protect the equipment such as pumps, valves, measuring and control equipment and other devices against damage, impurities accumulators are installed before them.
Flap valves are used as shut-off check valves at the end of pipelines in melioration systems, in water discharge and water charge accumulation systems, in water treatment plants, hydroelectric power plants and other areas of economic activity. Flap valves allow the passage of fluid only in the direction out of the pipe, and they are automatically closed after the liquid is released. The backflow and entry of foreign bodies into the pipeline are disabled.
MOUNTING - DISMOUNTING PIECES
Demounting pieces are used in pipelines as coupling elements. The use of these elements facilitates the installation of pipe fittings or any device into the pipeline, with the possibility of adjusting the mounting length within the limits that the demounting piece allows. The longitudinal compensators are installed in pipelines to compensate or displacements that result from heat and other dilatation. In addition to this function, they enable easy mounting of elements in the pipeline within the limits of available displacements.
Petroleum valves are used in the petroleum industry, oil refineries, warehouses of petroleum products, petrochemical and chemical industries. These valves are used as safety devices on the equipment. Air release valves are used to equalize pressure in reservoirs when they are loaded or unloaded, and to equalize pressure differences arising as a result of thermal expansion of fluid. These valves entirely automatically perform their function. Flame arresters are installed in the equipment in locations where it is necessary to prevent the passage of a possible flame. Oil safety valve is used in the petroleum industry as a safety device.
