Valves Products Valves Valves Sluice/Gate Valves A complete range of Gate valves for all of your high pressure and high temperature applications, proven over years of service in conventional thermal and nuclear power plants as well as other HP steam services around the world. Butterfly Valves KLN Butterfly Valves are designed and manufactured to have an optimum mix of structural stability, flow efficiency, and effective seating, coupled with the advantages of light weight, compact design, and ease of operation. Check/Non return valves KLN offers a complete range of check valves with a heavy-duty bolted cover, a renewable seat ring, and a body-mounted disc swing type. Valves are straight-through flow, which works automatically. Air release Valves The valve combines small and large orifices. It consists of a specially designed single small orifice valve and a single large orifice valve, with modified bodies to allow bolting together and free flow between them. Sluice/Penstock Gates KLN Cast Iron Sluice Gates are used in applications where safety and reliable performance are essential (dams, tidal environments, water treatment plants) and where outstanding product longevity is desired. Air cushion Valves In our Air Cushion Valve, the quick opening is achieved by a spring loaded air inlet port. The spring is designed to open at a preset pressure differential. The slow closing is achieved by using an orifice to expel the air at a controlled pressure and rate. knife Gate Valves Knife gate valves are designed mainly for on-off and isolation services in systems with high content of suspended solids. The knife gate valves are especially beneficial for handling slurry, viscous, corrosive and abrasive media.
