Keterangan BREATHER VALVE ( PRESSURE/ VACUUM RELIEF VALVE) - KANEKO SANGYO A breather valve is a safety device designed to ensure safe operation of a fixed-roof storage tank by controlling fluctuations of internal pressure caused by charge or discharge of the tank contents or by changes in atmospheric temperature or pressure. [ K SERIES: STANDARD BREATHER VALVE] Nominal Size : 40A--250A ( 11/ 2 " --10 " ) Body Material : IRON or STAINLESS.S. Seat Material : STAINLESS.S. Disc Material : STAINLESS.S. Standard breather valves having nominal sizes and functions suited for a wide range of applications. Easy to maintain owing to simple construction. [ KW SERIES: ALL WEATHER DESIGNED BREATHER VALVE] Nominal Size : 80A--250A ( 3 " --10 " ) Body Material : IRON or STAINLESS.S. Seat Material : PTFE Disc Material : PTFE Breather valves whose discs and seats are subjected to special treatment with synthetic resin for protection against freezing. Satisfactory operation ensured by many years of research and development in constant temperature rooms ( lowest air temperature: -30 degrees C) and testing in cold climate. [ KP SERIES] Nominal Size : 40A--150A ( 11/ 2 " --6 " ) Body Material : C.S. or STAINLESS.S Seat Material : STAINLESS. S Disc Material : STAINLESS. S Breather valves without metallic parts, suited for use with storage tanks for strongly acidic or strongly alkaline liquids that attack metals. [ KJ SERIES: STEAM JACKETED BREATHER VALVE] Nominal Size : 40A--150A ( 11/ 2 " --6 " ) Body Material : PVC or PP Seat Material : PVC or PP Disc Material : PTFE Breather valves used for tanks that store fluids required to be maintained at constant temperature. The inside of the valve body can be kept at a constant temperature by a steam pipe installed around the body.
